In 1968, this virus caused a lot of genetic changes. Four types of infectious viruses are - A, B, C and D, but A and D types are such types of viruses that cause seasonal respiratory illness in human beings on a frequent basis. -According to the IMA, the symptoms of this virus remain for 5-7 days and this virus also causes fever which subsides after 3 days, but coughing and sneezing persist for 3 weeks so people don't have to panic in this. -To avoid the H3N2 virus, we have to take some precautions like getting the flu vaccine (in case you have been suggested by your doctor), staying hygienic and maintaining social distancing (Just like what we did during the pandemic).
