Pigs transmit influenza viruses to people - mainly to hog farmers and veterinarians - and less often, the flu passes the infection to others.
According to data issued by the government, 169 deaths have been reported due to the H1N1 virus, for which 4,571 people have tested positive till Sunday.
Thanks to the weather, public health experts said the seasonal swine flu H1N1 could continue to hold its sway for a few more weeks, which was expected to put a lot of pressure on healthcare institutions.
As many as 512 cases of swine flu (H1N1) have been reported from various hospitals in Delhi till January 29, according to the data released by the government.
On being asked why the Health Ministry's data doesn't include the fatalities reported by these two hospitals in the city, a senior ministry official said, "Our data is based on the figures given by state governments".
As per data compiled by the National Centre for Disease Control (NCDC), Rajasthan is the worst affected state with at least 1,856 (40%) of the total cases being reported from the state as of January 27.
The recent figures are over double what was recorded previous year, with 750 cases reported in January 2018.
At a plenary session of the parliament, Davaajanstan Sarangerel denied the media reports that many children have died of swine flu in the country so far this year. Congress leader and six-time former Himachal Pradesh chief minister Virbhadra Singh, who was diagnosed positive for swine flu, was discharged on Tuesday. The RML has witnessed nine deaths, of which 8 people belonged to Delhi and one hailed from Haryana.
Rajkot district has also been reporting high numbers with two cases reported in Rajkot and one case reported in the Rajkot Municipal Corporation area on Monday. However, we can not report them as swine flu cases as we do not test everyone.
Swine flu is a seasonal viral infection and usually causes fever, cough, sore throat, diarrhoea, and vomiting.
