How many people get sick with flu every year?
A 2018 study by the CDC showed that an average of 8% of the US population gets sick with the flu each year. While it’s easy to shrug off this number as seemingly small, we have to consider that the US population in 2018 was well over 332 million, and 8% of that is an eye-popping 26.5 million. This is just the average too. Depending on the severity of the flu season, that percentage can go as low as 3% or roughly 9.9 million people, to as high as 11% or 36 million people. Clearly, these numbers show that influenza isn’t something that is so easily ignored. It is, in fact, an illness that health experts closely monitor all over the world.
While the flu seems to have developed a regular presence in our lives and is one that we encounter repeatedly, it is difficult to measure the actual number of people infected by the virus. Not everyone with the flu gets tested or seeks medical treatment. Most of the people we know, ourselves included, usually call in sick, stay home, rest, and self-medicate all the way to recovery without ever getting in touch with their doctor. This is true for mild to moderate cases, but some people don’t have this luxury and are hospitalized with a severe case of the virus. Based on these hospitalization rates, the CDC makes a statistical estimate of infections, divided by the census population, concluding with a number that best reflects the percentage of flu cases in a given year.
