Corona relaxation – 645 new infections in Austria – coronavirus

A total of 645 new corona cases were reported on Tuesday. Most of them in Vienna (205).

645 new infections were reported in Austria on Tuesday. The capital city of Vienna recorded the largest increase this time with 205 cases, followed by Upper Austria and Styria with 86 cases each.

The numbers in detail:

➤ Burgenland: 14
➤ Carinthia: 11
➤ Lower Austria: 85
➤ Oberösterreich: 86
➤ Salzburg: 77
➤ Steiermark: 86

In Wienthere was an increase from Sunday to Monday compared to 172 new cases, but a far lower level than in the previous week. However, the number of tests is declining.

So far there have been 39,303 positive test results in Austria. As of today (September 22, 2020, 9:30 a.m.), 771 people across Austria have died from the consequences of the corona virus and 30,312 have recovered. Currently 390 people are in hospital treatment due to the corona virus and 75 of them are in intensive care units.

Why the numbers on the dashboard can diverge

The Department of Health dashboard is a dynamic system and gets its data from the Epidemiological Register (EMS). The EMS is the official register in which the district authorities and laboratories enter. According to the Ministry of the Interior, there can be delays in making entries, especially in the morning.

In the Ministry of the Interior, on the other hand, the figures are collected via a video conference as part of the coordination of the state crisis and disaster management in the Operations and Coordination Center (EKC). These figures may include cases that are not yet recorded in the EMS.

The 6 p.m. news – Wastewater: the coronavirus is again very present in Île-de-France

Second wave? Resumption of the epidemic? Experts have been fighting each other on the subject for weeks, so much so that we no longer really know who to believe. This is an indisputable element this evening. It concerns wastewater in Île de France. The coronavirus is now at the same level as in March. This is what Vincent Maréchal, a virologist who is in charge of monitoring this wastewater, explains to us.

“Since the end of July and early August, there has been a further increase in the number of people carrying the virus. The levels we have today are indeed around those we had at the beginning of March“, concedes the virologist before continuing:” We do not know if we are at the beginning of a second peak of the same intensity. We must absolutely avoid finding ourselves in the situation we found ourselves in in March. We have multiple indicators that show that the virus is re-circulating, that it is actively re-circulating. More and more, the signals are coming on and the quantities of viruses that are detected are increasing, but they are increasing very slowly, ”explains Vincent Maréchal.

A different scenario, however

Irrefutable figures therefore since this wastewater is that of the entire population, not just figures from those tested. We therefore learn today that there are as many viruses in the stools of inhabitants of Île-de-France until early March. But be careful, this does not mean that we are in the same scenario.

Indeed, today’s sick population is younger. The 15-44 year olds are the most affected, and they are less likely to develop a severe form. In addition, this study proves that the virus circulates less quickly. In March-April, the rate detected in wastewater suddenly increased, today it is the opposite, it has been increasing very slowly since mid-June.

The virus circulates less quickly, resulting in: hospitals manage to manage the situation. In March, the intensive care units were completely saturated, which is not the case today. According to the ARS there are 1,300 intensive care beds reserved for Covid-19 patients throughout the Île-de-France, and of these 1,300 beds, only 278 are occupied.

80,000 infected per month, reproduction number 1.6 and up to 20 percent of positive findings – ČT24 – Czech Television

According to Dušek, the reproduction number was not published during the holidays because it did not make sense – the epidemic during July was practically invisible in our territory and existed only in a few relatively clearly descriptive bounded clusters – or groups. From the beginning of September, probably in connection with the return to normal life, the re-operation of schools, but also imports from abroad, the disease began to spread throughout the country, even faster than in the spring.

The reproductive number is not fixed, its size is affected not only by the properties of the virus, but especially by human behavior. According to international data, it seems that the citizens of the Czech Republic at the beginning of September almost did not limit their behavior or number of contacts at all compared to other countries – and because the obligation to wear veils was abolished until recently, the virus could spread very quickly.

According to Professor Dušek, the current measures are aimed at reducing the number of infections – whether by not meeting such a large number of people in one inappropriate place (up to half of the cases of infection occur in foreign conditions, hundreds of people), or that the virus hits a barrier – it can be drapes, properly washed hands, or a greater distance between people, which the virus is not able to overcome.

In fact, testing and tracing work the same way: if the infected person can be detected in time and proven to be really infectious, he will be able to infect far fewer other people. That is why the capacity of both the number of tests and the hygienists is constantly increasing. And an application can also help, such as the new version of the e-veil – she, in turn, warns the person against the infected and he can adjust his behavior so that he is not risky for others.

Percentage of positive tests

Thursday’s presentation by Professor Dušek and his colleagues also showed that the tests reveal a very high percentage of positive cases. And it’s not just daily data: this is convincingly demonstrated by graphs showing the average of positive cases over seven days. It shows that about 10.4 percent are infected.

At the same time, the World Health Organization states that if the cases detected are up to ten percent, then the epidemic in the country is under control, if this number is higher, then the country should be careful and quickly try to come up with measures to slow the spread.

At Thursday’s presentation, however, Professor Dušek showed another graph – it showed how many positive cases there were if they cleared themselves of the mandatory second tests; they are usually only negative. And their amount is even around 20 percent on some days, which indicates how fast the disease is spreading and also that hygienists can escape a number of other cases of infection.


Czechs discovered a new symptom of coronavirus? Scientists there are warning

Scientists in the Czech Republic have warned that COVID-19 may manifest itself as ulceration of the tongue. This poses the danger of confusing it in the first phase of infection with this rather common disease.

“Ulceration of the tongue is a direct symptom of SARS-CoV-2 infection, which occurs as a result of a disrupted immune system. Susceptibility of the oral mucosa to SARS-CoV-2 may be due to the expression of angiotensin-converting enzyme 2 (ACE2) in the epithelial cells of the tongue” – wrote Dr. Riad in the journal Oral Diseases.

Research has shown that ulceration of the tongue occurs among patients who have asymptomatic or mild disease.

– With viral infections, in this case SARS-CoV-2, various unusual symptoms may appear. Therefore, I would be very careful to argue that ulceration of the tongue may be one of the common symptoms of COVID-19, especially in people who are mildly infected, said Prof. Anna Boroń-Kaczmarska in an interview with the “ABC Zdrowie” portal.

The Ministry of Health informed about 757 new cases of coronavirus infection in Poland. Another 17 people are dead.

“We have 757 new and confirmed cases of coronavirus infection from the following voivodships: Małopolskie (92), Mazowieckie (88), Łódzkie (77), Wielkopolskie (75), Pomorskie (73), Śląskie (65), Podkarpacie (47), Kujawsko-Pomorskie (42), Lubelskie (39), Dolnośląskie (37), Świętokrzyskie (27), Warmińsko-Mazurskie (26), Zachodniopomorskie (20), Opolskie (19), Lubuskie (15), Podlaskie (15) “- we read in the release Ministry of Health.

At the same time, the ministry informs about another 17 victims of the disease.


Banks are closing branches in the Czech Republic. The fastest in 12 years, says the economist

Data from the Czech National Bank (CNB) show that in the first half of this year, banks’ net profit fell to 26.57 billion crowns. That’s about 19 billion less than last year. According to Kovanda, the reason for such a huge decline is the coronavirus epidemic, which hit the banks hard. Simultaneously with the closure of stone branches, the speed with which banks are switching to online communication with clients is growing.

In response to the consequences of the pandemic and the necessary measures associated with it, the banks have hastily accelerated the closure of stone branches. “At the end of this year’s first half of the year, the number of banking positions in the Czech Republic dropped to 1761. Compared to the end of March this year, 116 banking positions have decreased,” said the economist.

This is the highest decline between quarters since 2008. Year-on-year, about 8.3 percent of bank branches decreased, the highest in the last 11 years. According to experts, the rapid decline in profits is not only a problem for the Czechia, it is said to be a global problem.

Its primary reason is the uncertainty and fear of the effects of the second wave of the coronavirus pandemic. Companies are so hesitant to invest because they are not sure that the money will be returned to them. Demand for credit is also falling, and growing tensions between China and the United States are not helping.

“Central banks, including the CNB, want to make lending as easy as possible in such an environment, so they lower their key interest rates. However, they reduce the profitability of banks’ lending activities – normally measured by the net interest margin,” Kovanda described.

According to him, the profits of banks are also reduced by moratoriums (deferral of maturities) on loan repayments, which the Czech government introduced as one of the measures to combat the economic effects of the pandemic. According to economists, the situation in the Czech Republic is still relatively favorable compared to, for example, Italy.


Coronavirus: new record in Israel, over 5 thousand cases – World

The second most populous nation on the planet, which registered one million new infections in just eleven days, now has 5.02 million cases, just behind the United States which has 6.6 million.

The Robert Koch Institut in Berlin has included the Austrian capital Vienna among the coronavirus risk areas. The same institute announced it on its web page tonight. The criterion for inserting a locality among the areas at risk is the exceeding of 50 new infections per 100,000 inhabitants. In Vienna, there were 113 new cases per 100,000 inhabitants, reports Faz. This is the reason for the listing, which also includes Budapest.

Coronavirus infections surge to almost 4,000 more in the last 24 hours in the UK, a record since early May against the backdrop of a daily test level over 220,000. This is certified by the data released today by the government, also reporting an increase in daily deaths (20) and a slight but constant increase in hospitalizations in the ward or in intensive care (900 and 115 total patients, at the moment, in the entire country). Data in front of which Prime Minister Boris Johnson, during a hearing before the coordination of parliamentary committees in Westminster, assures however that “everything in our power” will be done to avoid a second national lockdown potentially “disastrous for the economy. “.

The surge of coronavirus infections in Malta appears unabated. The superintendent for public health, Charmaine Gauci, for the first time spoke of a “serious situation” as reported by the Times of Malta because the virus has entered some homes for the elderly, but above all there are more and more ‘isolated cases’ , a sign that containment is not working. In the last 24 hours a new all-time record has been reached, with 106 positives out of 2,470 tests in a population of just half a million inhabitants (1/120 of Italy). The two main teachers’ unions (MTU and Upe) have asked for the postponement of the physical reopening of schools scheduled for 28 September and are threatening strikes.

Strong increase in infections in Slovenia, where in the last 24 hours there have been 123 coronavirus cases, a new daily record since the beginning of the epidemic. Evidently contributing to this is the progressive increase in the number of tests carried out, which since yesterday were 3,123. The total number of positive cases has so far stood at 3,945, while the number of deaths has stood at 135, and there have been no victims for covid-19 for a couple of weeks.

Health reports 668,381 cases of coronavirus, in September 68,821 were added

Until this Sunday, in the country there were 82,870 suspected cases and 765,337 negative cases in the country and in total 1,516,588 people had been studied.

According to the Undersecretary of Prevention and Health Promotion, Hugo López-Gatell, the availability of beds in hospitals is 70% in the country; Colima is the state with the fewest free beds, with 56% occupied.

Six months after the pandemic began, the federal government considers that the country is on its way out.

López-Gatell assured in the conference that the hospital occupancy figures confirm that the disease is going down.

“We have already completed seven continuous weeks of a decline in the epidemic,” he declared this Sunday.

He recalled that only in seven of the 32 entities, there is an increase in cases of coronavirus, while in the remaining 25, they are already in a phase of decline for two or three weeks.

Some already 10 weeks of descent. There is no doubt that the epidemic is going down ”.

Hugo López-Gatell, Undersecretary of Prevention and Health Promotion.

López-Gatell affirmed that if and only if the conditions of an orderly deconfinement are maintained in the entities, there will be a sustained reduction, until eventually, he said, in October, there is a significant reduction in the pandemic.

The official of the Ministry of Health explained that, although the accumulated number of coronavirus infections exceeds 660,000, only 6% are active cases, that is, 40,178.


Restaurants singled out as probable places of Covid-19 contagion

A study published Thursday by US health authorities points to the likely role of restaurants and bars in the Covid-19 pandemic, while mitigating that of public transport and offices.

Contagions in beverage and restaurant establishments, where the wearing of masks is low or even nonexistent since it is necessary to open the mouth, have been suspected for a long time, and these remain closed indoors in many states. But few studies have rigorously sought to establish the hierarchy of the most risky public places.

Contact tracing in a few American states revealed this summer that bars and restaurants were the source of many contaminations.

The new study isn’t perfect and can’t confirm where people actually got infected, but it points in the same direction.

Experts from the Centers for Disease Prevention and Control (CDC) asked about 300 people to complete questionnaires in July in 11 US hospitals, half of whom tested positive, and the other half a negative test.

Among the questions: Did you go shopping in the 14 days before the symptoms? Did you take public transport? Did you go to a house with more or less than 10 people? Or at the office, at the gym, at the church, at the hairdresser, in a bar, a restaurant …?

They realized that negative and positive participants reported wearing the mask in similar proportions, and did not differ in their behavior for all of these places except two: bars and restaurants.

Twice as many positive cases went to a restaurant than negative cases, in the two weeks before the first symptoms. Ditto for bars for a sub-category (positive cases having no known contact with cases of Covid-19).

The analysis will have to be confirmed by others, in particular since it does not distinguish between interior and exterior spaces.

But it weighs in favor of wearing a mask to prevent contamination by droplets, whether they are relatively large (postilions, sneezes …) or microscopic, the track of the aerosolization of the microbe being more and more documented.
