Several states including Tamil Nadu, Delhi, Gujarat, and Karnataka are recording a spike in the H3N2 cases. According to the Union Health Ministry, Karnataka and Haryana have confirmed one death each from H3N2 influenza so far.
According to the Centre for Disease Control and Prevention (CDC), H3N2 is a non-human influenza virus that was first detected in 2011 in humans with genes from avian, swine, and human viruses and the 2009 H1N1 pandemic virus M gene.
The symptoms include fever, respiratory issues like cough and runny nose, as well as other symptoms including body aches, nausea, vomiting, or diarrhea.
Children below five years of age, people of age 65 years and older, pregnant women, and people with chronic diseases like asthma, diabetes, heart disease, weakened immune systems, and neurological or neurodevelopmental conditions are more prone to develop complications due to the H3N2 influenza.
