Public health organizations have explained that the reason there were far fewer cases of the flu in 2020 and 2021 was likely due to measures adopted to slow the spread of the virus that causes COVID-19, such as handwashing and social distancing. But a post on social media has spread the false claim that the dip in flu cases suggests that COVID-19 was a hoax.
How is COVID-19 transmitted?
to slow the spread of COVID-19 — such as wearing masks, keeping six feet apart, washing hands frequently and staying home — also slowed the spread of viruses that cause the flu.
That’s likely the reason that recorded cases of influenza dropped dramatically in 2020 and 2021, as explained by the, the , and many other and .
is caused by influenza viruses that spread mostly through respiratory droplets, similar to the way the virus that causes . Since the 2011-2012 flu season, the number of flu cases in the U.S. has been around 30 million each year with about 40,000 deaths, , which did not give estimates for the because of the low rates of infection.
But ahas gone viral on social media showing a from the WHO that demonstrates the dip in cases of the flu. The post includes text that references a well-worn but false claim that COVID-19 was a hoax, saying, “One of the greatest mysteries of COVID-19: Where did the flu go in 2020 and 2021?”
Social media users responded withsuch as, “Pretty much they repackaged that year’s flu strain as the rona & took away your civil liberties & destroyed the lives and businesses of thousands, if not millions of people.”
The post originated on, where it has amassed more than 7 million views, according to the site, and elicited a comment — “good question” — from Twitter CEO Elon Musk. It then spread as a screenshot meme to other platforms, including and , where it generated such inaccurate comments as “COVID is basically the influenza Flu.”
A WHO spokesperson told us in an email on April 12 that the current claim is also “not accurate,” adding, “the surveillance systems/testing for the two are entirely different.”
That’s because the flu and COVID-19 areillnesses caused by different viruses. As we said, the flu is caused by various types of . COVID-19, however, is caused by a specific type of coronavirus that was first identified at the end of 2019 — . That virus than viruses that cause the flu, and COVID-19 has since it emerged just over three years ago, which dwarfs the annual 40,000 killed by the flu.
COVID-19 killed more than 260,000 people in the U.S. in 2022,. In 2021 it killed more than 470,000 and in 2020 it killed more than 354,000, making it the in both years — behind heart disease and cancer — according to the National Institutes of Health. It’s likely to be the third leading cause of death again in 2022, , although official figures haven’t yet been released.
The WHO spokesperson also reiterated the point that’s been made widely by public health organizations and scientists for years: “One of the postulated reasons for the low levels of influenza activity was the effect of lockdowns and travel restrictions during that period.”
In fact, the level of recorded influenza cases for one strain of flu virus was so low in that period that researchers thought it may have disappeared entirely.
So, it’s wrong to suggest that the dip in recorded cases of the flu during the pandemic is a mystery or that COVID-19 is a hoax. The reduction in flu cases isn’t a mystery, and it’s been explained as the result of widely adopted measures that affect the spread of viruses.
