How does the H3N2 virus spread 

Former AIIMS-Delhi Director Dr. Randeep Guleria shared on the rise in influenza cases,“It spreads through droplets and mutates every year around this time.

"We had a pandemic many years ago because of H1N1. The circulating strain of that virus is now H3N2 and, therefore, it is a normal influenza strain. But we are seeing more cases because as the virus mutates a little bit, the immunity that we had against the virus becomes a little less and therefore people who are susceptible tend to get the infection more easily," Dr. Guleria told ANI.

Who does H3N2 Virus affect? 

H3N2 Virus can affect people of all ages, but a child under the age of 5 and people above age 60 are more prone to this virus.
