Viral cases are rising due to H3N2, Covid, and H1N1

India is seeing a surge in viral infections due to H3N2, Covid-19 and swine flu. While most of the cases are due to H3N2, data shows that swine flu and covid cases are also rising in the country.

As per the govt, H3N2 accounts for nearly 79% of all the influenza viruses found in samples taken from persons suffering from severe acute respiratory infections (SARI) or influenza like illness (ILI). Influenza B Victoria (14%), a subtype of Influenza B, is the second most common virus subtype and Influenza A H1N1 (7%), also known as swine flu, is the third most commonly detected influenza virus.

According to Integrated Disease Surveillance Programme (IDSP), 955 cases of H1N1 have been reported by states till February 28. The Union Health Ministry said that majority of the H1N1 cases, also referred to as swine flu, are reported from Tamil Nadu (545), Maharashtra (170), Gujarat (170), Kerala (42) and Punjab (28).

As per IDSP-IHIP (integrated health information platform) data, 3.97 lakh cases of acute respiratory illness/influenza (ARI/ILI)-like illness were reported from the country during the month of January, which increased to 4.36 lakh during February. Meanwhile, in the first nine days of March, 1.33 lakh ARI/ILI cases were reported, Times of India quoted an official as saying.

Last week, the health ministry confirmed that two people had died due to infection caused by H3N2, a subtype of Influenza A virus that is known to cause seasonal flu.

Meanwhile, Covid cases are also seeing an uptick in many parts of the country including Delhi which reported a Covid positivity rate of 3.24% with 13 out of 401 samples testing positive.

In a letter to states and UTs, Union health secretary Rajesh Bhushan said operational guidelines for integrated surveillance of respiratory pathogens presenting as cases of influenza-like illness or severe acute respiratory infection need to be followed.Bhushan also requested taking stock of hospital preparedness, such as availability of drugs and medical oxygen, vaccination coverage against Covid-19 and influenza. “While the Covid-19 trajectory has decreased substantially in the last few months, the gradual rise in Covid-19 test positivity rates in some states is a concerning issue that needs to be promptly addressed,” Bhushan wrote.

Meanwhile, doctors are advising people to wear masks since swine flu, Influenza A subtype H3N2 and Covid-19 are mainly through virus droplets.
