Virologist Netesov stated that it is possible to distinguish ARVI from COVID-19 only with the help of tests 
In acute respiratory viral infections (ARVI) and COVID-19 there is no difference between the symptoms, the disease can only be clarified through testing. This was stated by virologist Sergei Netesov in an interview with News.ru.
The specialist clarified that the coronavirus is of the same nature as ARVI. The diagnosis is made after PCR tests, tests for antibodies of the IgA class and antibodies of the IgM class are ready.
“You cannot distinguish them by eye. Symptoms, if someone says that he knows how to distinguish, this is a very self-confident person, “Netesov explained.
Earlier, a pulmonologist Sergei Babak compared the combination of COVID-19 and lung diseases with an” atomic bomb ” that explodes in the human body. According to him, if the virus is superimposed on other diseases of organs, in particular the lungs, then its danger increases many times.
