Hyderabad: In a recent surveillance to track Influenza- suchlike ails( ILI) and Severe Acute Respiratory Infections( SARI) carried out across the country by laboratories attached to the Indian Council of Medical Research( ICMR), a swell in seasonal flu cases was detected due to influenza A( H3N2) contagion.
The exigency of Influenza A( H3N2) as a dominant circulating viral strain wasn’t a surprise because, before the Covid epidemic, the influenza A contagion and its subtypes were the main contagions that routinely caused pandemics. In fact, the swine flu A( H1N1) touched off a major epidemic in 2009 and went on to infect a large sampling of people in Telangana till SARS- CoV- 2 came the dominant variant.
Influenza A Virus
Throughout the history of humanity, influenza( generally known as flu) is well known for causing pandemics including the Spanish flu of 1918 that claimed millions of lives. In 2009, a new strain A( H1N1) of influenza( swine flu) touched off a major epidemic in the United States, Europe, India, and other countries.
So far, experimenters across the world have linked four different influenza contagion types that include A, B, C, and D out of which the Influenza A contagion is the most noted one because it causes avian flu and swine flu.
The influenza A viruses beget respiratory complaints in humans and creatures and affect in regular seasonal affections, piecemeal from driving afflictions. According to the World Health Organization( WHO), worldwide the periodic pandemics due to influenza are estimated to affect about 3 to 5 million cases of severe illness and about to respiratory deaths.
