Experts say that it is a trend that we can see every alternate year. State surveillance officer, Dr Pradeep Awate, said, “This is the seasonal trend of influenza that is been noticed. Once the virus is spread in the community, people develop immunity against it which lasts for around nine to ten months. This short period immunity does not help them next year and then there is rise witnessed in the next year.”
“It is been noticed that after every alternate year there is rise and fall in number of swine flu cases. If one observes the pattern of these cases for the last eight to nine years this is the same trend that has been observed,” he added.
