Influenza claims 77 lives in Kerala this year as H1N1, H3N2 spread

Alappuzha: Influenza viruses, which spread through the air, can become more dangerous during the monsoon season. In Kerala, 10 people have died among 604 reported influenza cases in the past week. H1N1 and H3N2 strains have affected most patients. Poor adherence to social distancing and failure to wear masks during the rainy season are cited as major factors contributing to the spread.

The disease could spread further if adequate precautions are not taken, including in relief camps. Changes in weather conditions, along with genetic variations in the viruses, have also contributed to the spread. So far this year, 77 people have died among 6,650 reported influenza cases in the state. Influenza has recorded the highest number of deaths in the Health Department’s infectious disease list, surpassing leptospirosis and dengue.

The presence of the H3N2 virus began to be reported after the Covid-19 pandemic. Before that, the H1N1 strain was more prevalent. H3N2, a subtype of the influenza A virus, can cause pneumonia and breathing difficulties. It spreads more easily among people with low immunity, the elderly and pregnant women.

Symptoms

H1N1: Fever, body aches, sore throat, cough, diarrhoea, vomiting, chills and fatigue. The infection can become more severe in people with asthma, diabetes and heart disease.

H3N2: Cough, fever, vomiting, sore throat, muscle pain and breathing difficulties. Medical attention should be sought in case of persistent fever, chest pain, or pain while eating.

How it spreads

The virus can spread when an infected person sneezes, coughs or talks.

It can also spread when a person touches their mouth or nose after coming into contact with a surface contaminated with the virus.
