H3N2 virus is a subtype of influenza A that causes cough, breathing difficulties, high fever and other flu-like symptoms in those who contract it. Furthermore, doctors in Kanpur say that it is hard to differentiate this virus from Covid 19 as separate testing kits are required to test each of the many subtypes of influenza.

Commenting on the said spike in H3N2 influenza cases in Kanpur, Richa Giri (Head of Medicinal Department at Kanpur's Hallet Hospital) said that such cases are seen every year due to the change in weather, but the number of cases this year is rather high, with hundreds of patients reporting symptoms.
