Pune: The year 2017 saw an exponential rise in total number of cases of swine flu. Around 777 people lost their lives due to swine flu in 2017 whereas the number was only 26 in 2016.

Speaking to Sakal Times, State Surveillance Officer Dr Pradeep Awate said it is a trend that we can see every alternate year. “This is the seasonal trend of influenza that has been noticed. Once the virus is spread in the community, people develop immunity against it which lasts for nine to ten months.
“This short period of immunity does not help them next year and then there is rise witnessed in the next year,” said Dr Awate.
He added 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 the same trend has been observed,” added Awate.
In 2015, there were 8,583 positive cases, while in 2014, the total positive cases were only 115. While 2017 saw 777 swine flu deaths across the State whereas in 2016 there have been only 26 swine flu deaths.
