Most of the time, it has been noticed that influenza viruses happen to be benign and self-limiting.
This is what Dr G C Khilnani, chairman of PSRI Institute of Pulmonary, Critical Care and Sleep Medicine has to say, “But this year, patients suffering from the infection are reporting issues like persistent fever, prolonged cough, etc. At the same time, hospitalization has also gone up.” he said.

One major reason of this prolonged virulence of the H3N2 virus, which is aa subtype of Influenza A virus, it has become the reason to cause more hospitalizations as compared to its other subtypes.
As per the Ministry, there has been a close monitoring of the ICMR network of laboratories regarding the human Influenza virus in those suffering from Severe Acute Respiratory Illness (SARI) along with Influenza like illness (ILI).
The above trends actually began earlier this year. It all happened from January 2 to January 4 when experts spotted the pre-dominance of H3N2 virus in almost 80% patients.
The ICMR has already conducted a detailed survey according to which over 90% patients hospitalized for Influenza and ILI were positive for H3N2 virus. The patients were also confirmed of the symptoms like fever, wheezing, breathlessness, and more.
