The flu has begun hitting parts of the US earlier this year compared to the last five years, first picking up in late August to early September. While flu season typically starts in earnest around November, data used to track respiratory illnesses – like laboratory tests, hospitalizations and wastewater data – detected activity while summer temps were still scorching. So far this year, Influenza A is dominant as the number one strain. Influenza A is the most common type of flu that circulates seasonally and produces the symptoms we most often associate with the flu. If you have not gotten a flu shot yet, I would strongly encourage you to not wait and to get one now.
