The one who is also the spouse of the comedian François Massicotte shared a photo of her VERY many pregnancy tests on her Instagram account, but also a video on Facebook where she explains her journey in the fertility clinic.

“And there you have it, we can say it officially: I’m brooding a 4th Massi-Long!” She announces in the preamble.

“On August 25, I received a beautiful embryo at the Fertilys clinic. And after 27 pregnancy tests and a blood test …. it’s positive! Of course, there is never anything for sure, but I didn’t want to hide it. If the pregnancy is unfortunate, we have frozen embryos left for further testing. It’s also part of life. For the moment we are very happy! ”She clarified very honestly.


Bianca Longpré then thanked the professionals who supported her in this process at length.

“To all of those in the process: COURAGE. I think of you, ”she concludes.

Bianca Longpré and François Massicotte are already the parents of three adopted children: Ricci, Mimi and Billy.

Recognize 50 types of cancer by taking a blood sample – naturopathy & naturopathic specialist portal

Can a blood test reliably detect types of cancer?

The clinical use of an investigative blood test that can detect more than 50 types of cancer is currently being investigated. The special thing about this test is that all of these cancers can be detected with just a single blood sample.

A special blood test appears to be able to identify more than 50 different types of cancer from a single draw of blood. The test is currently being investigated as part of a clinical study in which the Cleveland Clinic is also involved. Previous results have already been published in the English-language specialist journal “Annals of Oncology“Published.

Cleveland Clinic joins PATHFINDER study

The researchers at the Cleveland Clinic have joined the so-called PATHFINDER study. This prospective, multicenter clinical study examines the clinical use of an investigative blood test to identify more than 50 different cancers from stages I-IV that only have a single decrease in cancer blood requires.

Test helps identify cancer faster

The new blood test aims to detect cancer at an earlier stage, otherwise these cancers may not be discovered until symptoms appear. A later identification of cancer leads to a lower chance of surviving such a disease. The PATHFINDER study is the first study to examine the implementation of the blood test in clinical practice.

What is so special about the test?

Such a multi-detection test for cancer has not previously existed. The researchers tried to find out whether this test is capable Krebs Detected earlier than is currently possible in asymptomatic people with an average or increased risk of cancer.

Testing could save many people’s lives

“Even if this test only detects a fraction of people with early-stage cancer, it will be the first time that we will be able to detect many types of cancer that are currently fatal when we could actually cure them,” reports Dr. Eric Klein of the Cleveland Clinic in one Press release.

Test could even determine where the cancer originated

The research shows that in cases where the test identified a cancer signal, it was able to determine with 93 percent accuracy which organ the cancer originated from. This means that decisive steps for treatment can be initiated more quickly.

Benefits from fewer false diagnoses of cancer

The test has the ability to detect cancer at a 0.7 percent false positive rate, which means that less than 1 percent of people without cancer are mistakenly identified as having cancer. A low false-positive rate is important in order to minimize the associated harm and fears and unnecessary follow-up examinations, the researchers add. (as)

Other research institutions are also currently working on a cancer diagnosis based on body fluids. The researchers at the Memorial Sloan Kettering Cancer Center called this method the holy grail of cancer diagnosis. More information can be found in the article Cancer research: uncover cancer through blood test.

Blood tests for cancer prior to the breakthrough?

TEstonians, test, test – as it sounds for weeks in the pandemic, and it could sound, if the cancer diagnosis is your way to the end, you years ago under the Label of “Liquid Biopsy” has entered, and with new remarkable results is paved. The idea is tantalizingly simple: a drop of blood to give, to rule out cancer or to detect the Tumor at least as early, that it can be treated with any prospect of success. This is possible because decay make the end of cancer cells in many cases, already in the first stages of growth with their bare, faulty genetic material and, often, very specific proteins into the blood and thus betrayed. In theory, anyway.

Editor of the features section, responsible for the area of “nature and science”.

In practice, the PR scandal has shown to the Heidelberg-based blood test for the early detection of breast cancer, how quickly desire and reality in the clinical practice can drift, if the competition is clouding the minds and work to do will see. What was the women are already as a tangible test of luck, and to this day it lies unfinished on the work bench of the “Hot-Screen”-laboratories. The demands on the accuracy are huge, who would want to in the case of cancer, also with the possibility of a false test result accept? The Heidelberg-based blood test is still being worked on, as is. However, the first brilliant stage wins go to the competition, you want to cut out the clumsy PR maneuver at the time. The American “CancerSEEK”Test, in front of four years of high-profile cancer researchers such as Bert Vogelstein presented for the first time, had as a multi-cancer test, significant weaknesses with regard to the accuracy of the forecasts. The announcement was that they wanted to find less than eight cancer types – ovarian cancer, liver cancer, stomach cancer, pancreatic cancer, esophageal cancer, colorectal cancer, lung cancer and breast cancer – even in asymptomatic patients. And at a reasonable price: $ 500. And that was another Argument: Even in the case of the cancer types such as breast and colon cancer, for which early detection programs are less than detected one-third of the tumors really early.

In the meantime, the blood test by doctors at the Johns Hopkins University, in a as it is, the first reality test has been tested to 10 000 women between the ages of 65 and 75 years. However, he was combined in the “Science” presented in the “Detect-A”study with a PET-CT scan, in order to get at the unclear Positive-Found more security in the diagnosis. Conclusion the patients the study: the combination of the number of early diagnoses could be doubled from 25 per cent, with the usual Screening to 52 percent. Two-thirds of the tumors were discovered prior to metastasis. The accuracy varied still considerably depending on the type of cancer, false positive test results but with an unprecedented specificity of more than 99.6 percent, in the combined method, apparently, is greatly reduced.

A Breakthrough? As a “promising” referred to formerly critical doctors in the journal “Lancet Oncology”, the American results. Of course, especially because a second blood test study at the Mayo clinic in the “Annals of Oncology” with a Test that tracks the epigenetic signatures of the misguided Tumor DNA and, apparently, even more than fifty different types of tumours display is capable of. Included in this study, nearly 6700 patients, of whom two thousand were sick in the course of time cancer. To discover tumors were more severe, the earlier the stage of your Cancer: Between 39 per cent, the sensitivity was in the first stages up to 92 per cent in stage four. After all: Who received a positive result, had a high probability of also actually a Tumor, the specificity was at the end at 99.3 percent. That all desires would be fulfilled to the accuracy of the Tests, we can say nevertheless is hardly. With greater security, by contrast, can at least say that the global race is heating up for market share in the blood testing business further.

Is it true that nicotine users contract Covid-19 less?

Hello,

Numerous case studies demonstrate this unequivocal : smokers who get Covid-19 have a risk greatly increased to develop severe forms of the disease. In this work, we find that the proportion of smokers is two to four times higher in severely ill patients than in those with a moderate form of the disease.

On the other hand, several publications relayed since the beginning of April report a counterintuitive phenomenon: in several countries, the proportion of smokers infected with SARS-CoV-2 would be lower than the proportion of smokers at regional or national level. The Minister of Health, Olivier Véran, recently mentioned this data.

In France, works being published conducted on a limited number of patients at the Pitié-Salpétrière, as well as a study in a school environment in Crépy-en-Valois (prepublished this April 23), also reported this statistical trend.

Many potential limits

Note now that the link between smoking status and propensity to be infected does not appear in all research. So in a recent study published in the Jama, involving 5,700 New York patients hospitalized for Covid-19, the proportion of smokers was analogous to that observed in the regional population.

The first studies were met with skepticism, not without reason. Indeed, many of these works have sometimes significant biases.

First limitation present in all studies (with the exception of French studies): the age parameter of hospitalized patients. Indeed, a significant proportion of patients with severe forms of Covid-19 are over the age of 65. The prevalence of smokers decreases very strongly with age (for example, in France, 65-75 year olds smoke 2.5 times less than the general population).

In the study conducted at Pitié-Salpêtrière, taking into account the age and sex of the patients, smokers nevertheless appeared to be four times less likely than non-smokers to be Covid +. A rate observed both in hospitalized patients and in patients treated on an outpatient basis. However, in order to draw more solid conclusions, these results should have been put into perspective with the smoking profile of patients who usually attend this hospital, at the same periods in previous years.

Another parameter that seems to be excluded from most analyzes: the socio-economic profile of the groups studied, which can strongly influence the expected proportion of smokers. A limitation mentioned by the authors of the French study, who established their calculations “Assuming that the population studied who lives in a limited area around a Parisian hospital has the same smoking habits as the French population in general”, and who note that “Healthcare workers were overrepresented in the outpatient group due to routine workplace testing when they became symptomatic”. The study conducted at Crépy-en-Valois seems to take this parameter into account. And its results are consistent with the Pitié Salpêtrière study.

Third important pitfall: the quality of the information collected is not always there … far from it. In some studies used by epidemiologists to conduct their analyzes, the smoking status of the sickest Covid + patients was simply not informed. Commentators have also noted that one of these studies considered individuals to be “non-smokers” less than 30 packages per year – preventing any comparison with national statistics which relate to all cigarette consumers.

For its part, the study conducted at Pitié-Salpêtrière seems to consider as “former smoker” any person who had quit smoking at the time of his hospitalization … without mentioning the hypothesis that patients may have stopped smoking because of the first Covid-19 symptoms! A point which would considerably influence the results. Requested by CheckNews, Zahir Amoura, author of this work, has not yet commented on this point.

Is the phenomenon biologically plausible?

The interpretation of these statistics, as well as the extent of the associated phenomenon, are still questionable.

Researchers, however, have begun to explore the hypothesis of a direct causal link between smoking status and primary SARS-CoV-2 infection. The question arises indeed: from a physiological point of view, is it plausible that lungs exposed to tobacco are less permeable to this coronavirus? Could nicotine be involved in the phenomenon?

A possible link with the ACE2 receiver?

SARS-CoV-2 infects cells by binding to the ACE2 receptor, abundant on the surface, in particular, the cells of the mucous membranes and the alveolar pulmonary tissue. The expression of the gene corresponding to ACE2 is not identical in smokers and in non-smokers. Based on animal models, smokers have long been considered to express less ACE2 – which suggests a simple explanation for the phenomenon: less ACE2 induces a lower propensity for infection.

But recent data, which seem to be corroborated by new researchsuggest that in humans, smoking is associated with a higher expression of ACE2. A higher propensity for coronavirus infection would therefore be expected. The epidemiological observations mentioned above, suggesting a protective effect of tobacco, would therefore raise a paradox.

Several explanatory hypotheses have been formulated. Some authors have advanced that in all patients, infection with SARS-CoV-2 would decrease the availability of ACE2 receptors in the lungs. The biological processes that usually mobilize these receptors would be hindered, leading to various symptoms of the disease. People with more ACE2, even if they were infected, would develop fewer symptoms. However, this interpretation is challenged by the Crépy-en-Valois study, where the diagnosis of infection was made on a blood test, and not on a simple clinical assessment of symptoms.

According to other works, the nAChR nicotinic receptor could modulate the activity of ACE2. Could stimulating nAChR make infection through ACE2 more difficult? This fact is not yet proven. “The possibility of a reciprocal modulation between ACE2 and the nicotinic receptor is an interesting scientific question for which we have no answer”, insists Professor Jean-Pierre Changeux, co-author of a scientific article inviting this hypothesis to be explored.

La Pitié-Salpêtrière has announced the launch of several clinical trials in this direction. The first, conducted on caregivers, aims to compare the infection rate between a group carrying nicotine patches and a group carrying placebos patches. More trials need to be done on Covid + patients in hospital to assess whether nicotine affects the course of the disease – especially in smokers who are forced to quit as a result of hospitalization.

Nicotine and vaping: preliminary data not very encouraging

The return of associations of electronic cigarette users does not seem to go in this direction, however. According to the analysis of a questionnaire sent in early April to several thousand members of the AIDUCE and SOVAPE associations, the rate of patients suspected of being Covid + was similar whether or not there was nicotine consumption – around 2.5 %. “Although it concerns nearly 10,000 people, this citizen survey is inconclusive on a major protective effect of nicotine, note the associations in a press release. The first data show no major positive or negative effect of vaping when faced with the risk of contracting Covid-19 for vapers and their entourage. ”

Tobaccoologist Bertrand Dautzenberg, who had encouraged these associations to explore this hypothesis, notes on Twitter that the data was not collected under conditions “Respecting all the obligations of scientific studies”. He nevertheless considers that they are not showing strong signs of a beneficial effect of nicotine in reducing Covid-19 levels. ” He invites an analysis of the Health Database to further explore this hypothesis.

No reason to start smoking

The tobacco specialist recalls “That tobacco certainly brings a negative effect greater than that of a small benefit which is not confirmed at all”. “This leads to encouraging all doctors to advise and support smoking cessation for all smokers.” The authors of the Crépy-en-Valois study abound in this sense, recalling that tobacco is responsible for 75,000 deaths per year in France. “Smoking cannot therefore be offered as a way of protecting oneself against the new coronavirus”, they insist.

Unsurprisingly, this finding is similar to that of the authors of a review on the complications of Covid-19 related to smoking. “Risk factors for severe forms of Covid-19 (pulmonary and cardiovascular disorders, diabetes, etc.) are more common in smokers. Smokers with comorbidities should quit smoking by all means. ” They also observe that confinement can lead to social isolation and psychological distress that increase the need for smoking. [En outre], smoking is more prevalent among the economically less advantaged groups, and they are potentially more at risk for Covid-19. ”

For its part, the association Alliance contre le tabac urged the greatest caution with regard to speculative information in circulation. In the absence of more evidence, nicotine users, “Should not expect to be more protected than the population from the current epidemic”, she recalls. In addition, she advises non-smokers to use nicotine substitutes. A warning also formulated by the promoters of the Pitié-Salpétrière study or by the Minister of Health.

In summary

Although well publicized, epidemiological observations associating smoking and the risk of developing the symptoms of Covid-19 are difficult to interpret at this time. Under the hypothesis of a real cause and effect link, the biological mechanisms mentioned in the press are still hypothetical. None have yet been formally tested.

Listen to the weekly behind the scenes podcast of CheckNews. This week: Covid-19: what are the real figures for deaths in intensive care?

Jérôme Salomon, the Director General of Health, mentioned a mortality of 10% in intensive care of patients hospitalized for Covid-19. In this episode, Luc Peillon explains why this figure is largely underestimated.

Organized fraudsters take advantage of the corona crisis

I.In the Netherlands, 52 delivery vans were already ready to bring ten million respirators to North Rhine-Westphalia. They should be accompanied by the police from the border. The country had transferred almost 15 million euros to a Swiss sales company. But the business never came about: the company had been exposed to fraudsters. It was exposed earlier in the month. Investigators in several European countries were involved, including the EU police force Europol, based in The Hague. Since the beginning of the corona epidemic, she has been particularly concerned with related crimes.

“Organized criminal groups are notoriously flexible and adaptable,” says director Catherine De Bolle. You can also experience that in this crisis. The fraud case exemplifies how the perpetrators proceed. The sales company commissioned by North Rhine-Westphalia turned to a Spanish company that offered protective masks over the Internet. What she did not notice: she had fallen for a fake website that was modeled on that of a real company, only with different contact details. The “Spaniards” first confirmed the desired ten million masks by email, but then referred them to a “trustworthy dealer” in Ireland.

This in turn brought the Swiss into contact with a Dutch supplier. He asked for 1.5 million euros in advance before delivering the first tranche. The money was transferred to an Irish account, but shortly before the planned delivery, it was said that the amount had not arrived. Now 880,000 euros would have to be immediately to ensure the delivery. So it happened, but the goods never came. The Swiss company filed a complaint. As it turned out, the website of the Dutch provider had also been cloned.

Broken 37 criminal networks

At Europol it is said that such cases are becoming more common. Fake websites could be purchased as a service on the Darknet. After all, the investigators succeeded in stopping the flow of money and blocking accounts in good time. Two people were arrested in the Netherlands. The other business model that is flourishing in the Corona crisis is product piracy. Providers quickly recognized what was in demand on the market. In the first wave there were protective masks, disposable gloves, disinfectants, antibiotics and pain relievers.

In March, 37 international criminal networks were broken up in an international operation, and more than a hundred people were arrested. The seized medicines alone had a commercial value of 13 million euros. Thousands of links were removed that led to illegal offers on the Internet.

Now, in the second wave, blood tests are needed that promise rapid detection of infection. Buyers are also looking for much-reported medication because some scientists hope to help with Covid-19. This includes the active ingredient remdesivir, which has been tested against Ebola. Chloroquine, which is used against malaria and has already been praised as a “gift from God” by the American President Donald Trump, is currently in particularly high demand. Such drugs are prescription-only, but are also available online without a prescription, as Europol has shown in a new study.

Fake blood tests and poor protective masks

Investigators saw offers for chloroquine on the trading platforms Empire, Dark Bay, Bitbazaar, CanadaHQ, Yellow Brick and Europa Market. These virtual shops are controlled by software that buyers and sellers use to disguise their identity. Fake blood tests and defective protective masks can also be bought online. After all, the largest retailer Amazon is acting on its own initiative against dubious providers. The company works with Europol.

The European Police Authority Europol is based in The Hague


Counterfeit pharmaceutical products have been sold on the Internet for a long time. Sometimes it is regular goods that are traded illegally, i.e. without a prescription. Sometimes medications contain no or not the specified active ingredients, which can even make illnesses worse. According to Europol, most of the counterfeit products come from China and India. Some of them are also manufactured there by approved companies.

They often end up on the European market via intermediate stations in Turkey and Ukraine. They are transported by sea and as smaller packages by air freight. Sales in Europe are managed by organized groups. Most of the suspects targeted by the European police force come from Poland, Romania, Ukraine, France and Bulgaria. The Italian mafia also makes money from it.

Europol writes about the sales in the new study that they are “probably very considerable”. When asked, it was said that the longer it took a vaccine to become available, the more money criminals could make with people’s fear. The amounts should go into the billions.

Early cancer detection with blood test: All about Liquid Biopsy

Blood sampling can provide information about various things. Deficiency symptoms, problems with the thyroid gland, inflammation values ​​- and also whether a patient has cancer or not. “Liquid Biopsy” makes it possible: Samples of non-solid, biological tissue, especially blood, are examined largely non-invasively. Similar to conventional biopsy, this procedure is well suited for the diagnosis and monitoring of cancer. And here is a new milestone to be announced. The “Deutsche Ärzteblatt” reports on this among other things.


There have been several possible test procedures for various types of cancer via liquid biopsy. We will introduce one of them to you below. Now researchers have managed to get one Develop a blood test that detects 50 different types of cancer via Liquid Biopsy can.


Detect 50 types of cancer: This is how the Liquid Biopsy works


A prospective case-control study, published in the Annals of Oncology, showed that the test, developed by a US company, can detect 50 different types of cancer. And the further astonishing thing about it: The false positive rate, i.e. the rate of cases that were diagnosed but in which there was no illness at all, was only 0.7 percent! This false positive rate was a problem that previous tests had to grapple with, as it has been much higher so far.

How does it all work? A liquid biopsy test detects genetic mutations in cancer cells via DNA. Cancer is basically the result of mutations and other changes in the genome. The mutated cells, cancer cells, multiply and form a tumor in most cancers. When cancer cells decay as a tumor grows, fragments of their DNA flow into the blood. If these changes in the blood can now be detected, it can quickly be determined whether the person tested has cancer or not. So far, this can only be demonstrated with some cancers if the tumor is large enough. With cancer, however, it is often vital for the survival that the disease is recognized as early as possible.


The problem is that these DNA fragments can be so different that it is difficult to identify them precisely. And now the breakthrough could have been achieved.


Method can distinguish fragments of DNA


First of all, a common denominator had to be found. And the US company “Grail” might have found it. With their test, so-called “methylation patterns” of the cell-free DNA detected in the blood can be determined – and thus DNA fragments from cancer cells can be distinguished from cell-free DNA from body cells. These methylation patterns also indicate what type of cancer it is.


To test whether this test is reliable, studies were carried out on blood samples from almost 6,700 people. Around 2,500 of these had a known cancer, but have not yet been treated. 4,200 other people without cancer were tested.


In doing so, it was possible to find out which patterns could be specific for a cancer, ie which they could show. According to the researchers around Michael Seiden from “US Oncology” (private provider of cancer treatments from Houston, USA), a specificity of 99.3 percent was achieved. Accordingly, the test was only positive in 0.7 percent of the study participants who did not suffer from cancer.


This result is so important because unnecessary follow-up examinations, which are expensive on the one hand, and above all, on the other hand, leave the false-positive people in an uncertainty that is difficult to bear. Because they believe that they have cancer, even though they are actually not.


The higher the stage, the better the detection rate


A liquid biopsy would have the greatest benefit if it recognizes cancer as early as possible, i.e. best in the first two stages. The detection rate for the correctly positively recognized cancers is not so high – it was around 67 percent for the twelve most deadly cancers. This affects anal, bladder, colon, esophagus, stomach, head and neck cancer, cancer of the liver and bile ducts, lung, ovary and pancreatic cancer, lymphoma / leukemia and multiple myeloma. The detection rate was highest in the advanced stage. But even in the early stages it was 39 percent in stage I and 69 percent in stage II for the twelve diseases mentioned above. In all 50 types of cancer tested, it averaged 18 percent in stage I, 43 percent in stage II, 81 Percent in stage III and 94 percent in stage IV.


Further studies are now to follow


Now two more studies are to follow: The so-called SUMMIT study is to test how successful the blood test for early detection can be on 50,000 people with an increased risk of cancer due to long-term tobacco use. And the PATHFINDER study examines how this test could be integrated into practice.


The test could also be of interest to patients in whom tumor metastases have been found whose origin, i.e. the primary tumor, is still unknown. In the study, it was possible to identify the origin of the cancer in 96 percent of the cases – using the methylation pattern of cell-free DNA mentioned above.


The cancer diagnosis ensures a life between fear and hope. More guides and Article about cancer can be found on our topic page.

On January 22, 2018, BILD der FRAU reported another test using the “liquid biopsy” method:


Scientists from the “Johns Hopkins” University in Baltimore have just published a report in the journal “Science” that a procedure called “Liquid Biopsy” (English “liquid biopsy”) can detect eight different types of cancer at an early stage. This would revolutionize cancer prevention, which has so far been associated with frequently unpleasant examinations such as mammography or colonoscopy.


“Liquid Biopsy”: cancer detection thanks to special blood analysis


For the study at the “Johns Hopkins” University, blood was drawn from over a thousand people with cancer and analyzed using the “Liquid Biopsy” method. Even the smallest particles in the blood are detected, which indicate certain cancers. Cancer was also found in the blood test in 70 percent of the people tested. The test can detect the following types of cancer:


  • Breast cancer
  • Colon cancer
  • Liver cancer
  • Lung cancer
  • Ovarian cancer
  • Pancreatic cancer
  • Esophageal cancer
  • Stomach cancer


Such a form of diagnosis would have countless advantages for those affected. Blood sampling is simple and straightforward for the patient – no comparison with some other examinations. In addition, doctors could discover some particularly aggressive types of cancer at an early stage, which would significantly increase the chances of recovery. For patients who have already had cancer, a regular blood test could provide information on whether there is a risk of relapse.


Process not yet fully developed


Although the progress in research on “Liquid Biopsy” is really promising, you shouldn’t be too early to look forward to it. The process is not yet mature enough to actually become common practice. The following problems still have to be solved:


  • According to German experts, the risk of mistaken cancer diagnoses is very high. This could lead to patient insecurity and unnecessary follow-up examinations.
  • The location of the tumor cannot be determined by the blood test in all cases. For the patient, that means knowing that you have cancer, but not where it is. Very difficult for the psyche and further treatment.
  • So far, the method has only been used in patients with cancer. But: “With a recognized screening procedure, a single person suffering from cancer without symptoms from several hundred healthy people and people with other diseases must be correctly identified,” says the German Society for Pathology in a statement on the procedure.


So there is still a lot to do for the Baltimore researchers. But there is no doubt that their work gives hope for a healthier future.

Important blood test for asymptomatic corona cases

Researchers at the Icahn School of Medicine in New York have developed a blood test that can indicate whether a person has ever been infected with the new corona virus. That reports Technology Review online in “Blood test shows actual coronavirus spread”. The one MedRxiv pre-publication The test described searches for antibodies against Covid-19 in blood samples and thus resembles the most frequently used detection test, for example for HIV.

The test can be used to find out how many people are actually infected or have had contact with the pathogen and are now immune. Because a lot of people get infected, but develop little or no symptoms. On the one hand, knowing their number is important for disease modelers so that their prognoses are more accurate. Governments also urgently need the test to decide how strong foreclosure measures are needed for the population.

The new corona virus has more than worldwide 10,000 people killed. This corresponds to approximately four percent of the 244,600 confirmed cases and results in a shocking mortality rate (as of March 20, 2020). However, the actual mortality rate is certainly lower and possibly much lower. So far, however, epidemiologists have not been able to quantify them precisely. Essentially, the modelers lack the exact denominator of the mortality rate calculation: For this, one divides the number of people who died from the corona virus by the number of all infected.

Coronavirus deaths in New South Wales rise to five after the highest 24-hour infection peak

updated

March 18, 2020 2:26:28 PM

The number of coronavirus-related deaths in New South Wales has risen to five and the total number of infections in the state is now 267.

Key points:

  • An 86-year-old man died after the worst 24 hours of infection in New South Wales
  • Health authorities say this is partly due to people returning from the UK, the U.S. and Europe
  • They also said that it is becoming difficult to monitor the spread of the virus

NSW Health said an 86-year-old man who tested positive for COVID-19 died last night in a Sydney hospital.

A spokesman for NSW Health said: “Our condolences are with your family and friends right now.”

There have now been six coronavirus-related deaths in Australia.

New South Wales has recorded 57 new cases since yesterday, the biggest peak in a 24-hour period.

During a press conference, the state’s chief health officer, dr. Kerry Chant said the wave of cases was in part due to “incredibly high test rates in New South Wales”.

“We have passed 25,000 tests well and continue to test large numbers of people every day,” he said.

Dr Chant also attributed the sharp increase in cases to the influx of travelers returning from a “series of countries” in recent days.

Dr Chant said the epidemic has “changed and evolved”, citing a large number of travelers from the United Kingdom, the United States and Europe.

“What we have seen is increasing the number of travelers returning from Europe and America, adding to the previous countries we have had … Iran, South Korea and Hong Kong,” he said.

Health authorities are scrambling to track down people who had been in contact with COVID-19 patients to instruct those people to self-isolate and monitor the symptoms of the virus.

But the dr. Chant said that this is increasingly difficult as numbers continue to rise.

“We have also observed an increase in the number of cases in which we have not been able to find a source of that infection,” he said.

Dr Chant said that the state’s limited transmission rates are the result of the fact that NSW has “one of the most liberal testing policies” and stressed that those at risk must be tested for COVID-19.

Your coronavirus questions answered:

High risk categories include anyone who has returned from abroad and has developed symptoms including fever, cough and breathing difficulties, people hospitalized with acute respiratory infections and anyone who has come into contact with a coronavirus case.

“We have had extremely high test rates in New South Wales, which compares very favorably with some of the major jurisdictions that test numbers overseas,” he said.

NSW Premier Gladys Berejiklian has called for calm.

“I want to echo [Dr Chant’s] words in which we have one of the people with the highest number of people tested [in Australia]”Said Berejiklian.

What coronavirus experts say:

Ms. Berejiklian also claimed to support the Prime Minister’s advice to keep schools open.

Among parents’ growing concerns, students who interact closely in classrooms or gather outside can increase infections.

“What we are urging is for parents to cooperate with the key message, if you have a sick child, a child with even just something you would have sent them to school in the past, please act prudently and keep them at home in this time, “said Berejiklian.

He said the parents and health care workers of schoolchildren should support this behavior “for a long time, which is about six months.”

Morrison previously said he would continue to send his children to school and cited Singapore as an example of a country that has not seen accelerated rates of coronavirus infections despite opening schools.
