As many as 736 persons have died due to the deadly H1N1 virus in India since January this year, latest data from Union Health Ministry reveals. Up to 15,121 persons have been infected with the virus until July 30 this year.

Maharashtra has the largest number of infections, up to 3,450, and has recorded the most deaths up to 358. Following close on its heels is Gujarat with 549 cases and 107 deaths.

While 70 persons died of swine flu in Kerala (1,285 cases) this year, 59 persons died in Rajasthan (422 cases), and 15 succumbed in Karnataka (2,732 cases).

“Every few years, the virus mutates. While in 2009-10 it was a deadly blow and had been declared pandemic, over the years its potency has reduced,” said a health ministry official.

The official stated that there is an antigenic drift over the years where the virus naturally mutates over time. “En om de paar jaar is er ook een antigene shift,,en,dat een ander virus opkomende pandemie te zullen zien,,en,dan degene die we hadden een paar jaar geleden gezien.,,en,Een antigene verschuiving zal mutaties van het virus, die zal leiden tot verlies van de immuniteit in de massa voor de nieuwe mutaties te betrekken en zal ook leiden tot een vaccin mismatch,,en, which will see a different virus emerging to be pandemic, than the one we had seen a few years ago.”

An antigenic shift will involve mutations in the virus which will lead to loss of immunity in the masses for the new mutations and will also cause a vaccine mismatch.
