With the current strain of flu infection, one reason for symptoms to last longer is the risk of lack of exposure. While flu infections were minor last year, we were also taking proper hygiene measures. Now, not only has our exposure to the flu virus decreased, the incubation period of the virus is also something we should consider, which refers to the time between contracting the virus and developing symptoms. For the flu, a typical incubation period can be 2 days, but it can also last up to 4 days.
Since, with the flu, there is a risk of spreading a more prevalent infection than with COVID (as we are more vigilant about COVID right now, and can dismiss the symptoms of flu as in a regular cold), it is highly risky and It may be easy to spread the infection to others. Experts also say that when a person has the flu, they are most contagious in the first 3-4 days, when they are more likely to experience symptoms such as coughing and sneezing, which can release respiratory droplets. Huh. The risk of infection, like COVID, may be higher the day before you start experiencing symptoms.
