ICMR Says Seasonal H1N1 Surge Needs No Masks
India is seeing more seasonal flu infections than usual.
The main virus involved is called H1N1.
Smaller numbers of other flu viruses and mild COVID-19 cases are also being found.
Rajiv Bahl of ICMR said nearly all cases are mild and usually improve with rest, fluids and basic care.
He said most people do not need to wear masks for this flu.
People should wash their hands, cover coughs and keep some distance from sick people.
Older adults, pregnant women and people with weak immune systems should ask their doctors about flu vaccination.
Health workers are testing samples across India to watch how the virus changes.
India’s current respiratory-infection surge is driven mainly by seasonal Influenza A subtype H1N1, with limited H3N2, Influenza B and mild SARS-CoV-2 circulation.
ICMR chief Rajiv Bahl said about 98–99% of cases are mild, self-limiting and manageable at home.
Instead of routine masks, officials recommend hand hygiene, respiratory etiquette and keeping one to two meters from symptomatic people.
High-risk groups may consider the Northern Hemisphere flu vaccine after consulting their doctors; universal vaccination is not part of the national programme.
Delhi has reported more than 2,600 influenza cases this year, while ICMR is monitoring mutations through 73 sentinel hospitals and 167 laboratories.

Director general of the Indian Council of Medical Research
“Flu viruses have a very classical way of behaving; they keep on having small mutations every year. That mutation helps them to keep on infecting people even if they had the flu last year.”

“There should not be any cause of panic that we can see, any cause of concern. It is a large number of cases with the same H1N1 strain, which is the seasonal influenza.”
