However, the relaxation of Covid-19 norms, resumption of physical settings like schools and offices, and reduced cases of coronavirus infection may further stem influenza or flu this year. This adverse effect, in turn, may stimulate more severe, virulent epidemics. Moreover, reduced absence of circulation of and exposure to pathogens such as the influenza virus and the respiratory syncytial virus (which causes severe pneumonia) can decrease herd immunity. Thus, we cannot really be sure of the actual statistics, unless people get tested more often. Limited or no testing for influenza can be one reason for the vast difference in numbers. While it may seem like a good mark, epidemiologists are divided over whether we should be happy about it. Multiple medical journals and scientists have stated that many countries did not see the seasonal flu epidemic. India is not the only country with such fewer numbers of flu in these pandemic years.
However, 2019, the year before the pandemic, had as many as 28,798 such cases. Increased emphasis on hygiene and cleanliness in public/shared spacesĭata suggests that 2020 had only about 2,752 seasonal influenza (H1N1) cases in the country. Last year barely saw an uptick or rise in the number of flu cases. Covid-19 has an array of distinguishing signs like loss of smell and taste, among others. The symptoms of Covid-19 and common cold/flu overlap, with similar ones being – fever, body ache, chills, sore throat, fatigue, etc. This reason is why people may get down with the seasonal Flu more often in 2021. Weather experts say this year, La Nina (cooling phase of the El Nino Southern Oscillation (ENSO) phenomenon) will bring colder, wetter winter months. With temperatures dipping in various parts of the country and heavy rainfall occurring in a few regions, we might witness the onset of increased common cold and flu.
