KOMPAS.com – Corona virus SARS-CoV-2 as a cause of disease Covid-19 is still being studied today.
Moreover, its spread is still increasing every day in a number of countries in the world.
Until now, nearly 25 million people are infected with this disease, which attacks many of the respiratory organs.
For almost 8 months since it was reported in early January 2020, researchers are still continuing to gather about the disease.
Starting from the mode of transmission, symptoms, effects, vaccines and effective treatments to cure it.
While much remains unknown about this virus and disease, there are at least some understandable things about it corona virus This Covid-19.

Here are seven things you can learn about viruses corona so far:
1. Reinfection of the corona virus
Researchers in Hong Kong claim to have the first evidence of someone re-infected with the virus.
Dr. Anthony Cardillo, CEO of Mend Urgent Care and ER doctor, said that a person can be 100 percent reoculated with Covid-19.
“What is not known about Covid-19 is whether the first infection you have provides immunity to this second infection? Nobody knows the answer to that question,” Cardillo said quoted from abc7.com (28/8/2020).
The technical leader for Covid-19 from the World Health Organization (WHO), Maria Van Kerkhove said that re-infection is still possible.
Even though someone who has recovered from Covid-19 already has its own antibodies in his body.
According to him, as quoted by Fox News, it is not certain how strong the body’s immune system is from the corona virus and how long it will last.

2. Symptoms for a long time
“There are many studies in several countries that show that weeks to months later, patients still experience symptoms such as shortness of breath, numbness and tingling in their extremities, their arms or legs,” said Dr. Michael Daignault, emergency room doctor at Providence St. Joseph Medical Center.
3. Children can catch and spread Covid-19
So far, the corona virus is more common and susceptible to infecting people over 60 years of age.
This includes patients with comorbid or congenital diseases such as diabetes, hypertension and heart disease.
But with Covid-19, children can catch the coronavirus and spread it, but there are many things that are not yet known.
“Children aged 10 to 11 years and over can spread the virus as well as adults,” said Dr. Rishma Chand, pediatrician at Dignity Health Northridge Hospital.
“We don’t know much about the infection and the younger children,” he said.
Chand said the most common symptoms reported in children were fever and cough.

4. You can test positive after recovering from Covid-19
Doctors said patients could still test positive for Covid-19 after recovering from symptoms of the virus.
Research shows that the most common method of transmission is via respiratory droplets, such as coughing or sneezing.
Dr. Cardillo ensures that Covid-19 can be transmitted by touching a surface and then touching your face.
“This test is sensitive for the virus’ mRNA,” said Daignault.
“So it’s just a fragment of the virus left in the nose in the mouth that doesn’t indicate that the patient is still infected or catching the virus.”
5. Viruses survive on the surface of objects
A number of studies at the beginning of the pandemic stated that the corona virus can survive a certain time on the surface of objects.
However, the method of transmitting the corona virus by touching the surface of the object with the virus is considered not the main one.
“It’s impossible to get infected like that because person-to-person contact is a risk of droplet transmission, but both are modes of transmission of the virus,” Cardillo said.

6. Antibody testing has not been reliable
Doctors say the reliability of the antibody virus test is still less accurate than the swab or PCR.
“The usefulness of antibody testing is limited,” says Daignault.
“It’s great if you do it immediately after infection. But if you do it two or three months later and you don’t have antibodies in your test, it’s not,” he explained.
7. Vaccines are in process
In early August, Russia claimed to release coronavirus vaccine first. Despite this the international medical community is still skeptical.
In America, Dr. Cardillo said there are six strong competitors currently undergoing phase three of clinical trials.
“They’re enrolling tens of thousands of people, they’re all getting vaccinated now, and we’re watching to see who is infected and watching how many of those vaccinated are very sick versus just mildly ill,” said Dr. Cardillo.
Dr. Cardillo expects a vaccine in America in January or February 2021.

Still will be studied
Meanwhile, an epidemiologist from Griffith University, Dicky Budiman, said the research would continue until all the lines of information needed regarding Covid-19 were fulfilled and answered.
Starting from how the virus survives, infects humans, how humans respond to viral infections, and how the virus is transmitted from one person to another takes place.
“Then how does this virus react in the human body in the short to long term and what is the mechanism of action of this virus in infecting humans so that we can know the strategy, which is linked to the discovery of definitive drugs and vaccines,” said Dicky. Kompas.com, Friday (28/8/2020) afternoon.
If all these things have been found, then according to him, information about one disease is relatively well established, in this case Covid-19.
“Among other things, how many virus particles can infect, we don’t know yet. Then we don’t know all of the long-term and medium-term impacts of this virus,” explained Dicky.
“And also the ability of this virus to ‘trick’ our body’s defense cells is also partially known,” he continued.

Therefore, Dicky said a lot of research was still needed in order to know the complete and complete characteristics of the corona virus.
“So this will continue to need to be researched. I predict that maybe we can only find out about this until next year. At least we can start to know more, almost all of them know about the pattern, and how the impact of the Sars-CoV-2 virus in infecting humans.
