Flu Has Disappeared Wordlwide during the COVID Pandmic
Whilst the Covid pandemic rages on, data shows that the incidences of the common flu or influenza have dropped dramatically.
“The U.S. saw about 600 deaths from influenza during the 2020-2021 flu season. In comparison, the Centers for Disease Control and Prevention estimated there were roughly 22,000 deaths in the prior season and 34,000 two seasons ago.”
The article features charts for Latin America and Oceania which show that this disappearance of the flu is a global phenomenon.
“The reason, epidemiologists think, is that the public health measures taken to keep the coronavirus from spreading also stop the flu. Influenza viruses are transmitted in much the same way as SARS-CoV-2, but they are less effective at jumping from host to host.”
But this may not necessarily be all good news.
“Because each year’s flu vaccine is based on strains that have been circulating during the past year, it is unclear how next year’s vaccine will fare, should the typical patterns of the disease return. The WHO made its flu strain recommendations for vaccines in late February as usual, but they were based on far fewer cases than in a common year. At the same time, with fewer virus particles circulating in the world, there is less chance of an upcoming mutation, so it is possible the 2021–2022 vaccine will prove extra effective.
Public health experts are grateful for the reprieve. Some are also worried about a lost immune response, however. If influenza subsides for several years, today’s toddlers could miss a chance to have an early-age response imprinted on their immune system. That could be good or bad, depending on what strains circulate during the rest of their life. For now, future flu transmission remains a roll of the dice.”
