H3N2 influenza, AKA "Hong Kong flu,"  is a strain of the Influenza A virus that is capable of causing respiratory illness in humans.

According to the India Council of Medical Research (ICMR), H3N2 has resulted in more hospitalisations than other flu subtypes.

H3N2 influenza is highly contagious. It can easily spread from an infected person.

It can spread through coughing, sneezing and talking.

People with underlying diseases, pregnant ladies, children and the elderly are most vulnerable to the virus.

If you’re sick with the flu, stay home until 24 hours after your fever has gone down to avoid transmitting the disease.

It is advised to wash hands regularly, avoid crowded places, to wear a mask when sick.
