Anyone else seeing the headlines, "SUPER FLU is SURGING!" all over the place? Seasonal flu has quickly increased in the US over the past two weeks. Cases of influenza have surpassed the peaks of the past five seasons, due to a new K subvariant of the H3N2 strain. This K variant emerged after the vaccine was chosen, so this is a mismatched year. Also, less than 25% of Americans have gotten vaccinated and the new variant is better at side stepping previous immunity. So, overall, more people are susceptible to the virus. As more people are getting infected, we are seeing an expected increase in severe cases. However, hospitalizations due to flu are following a similar trend to previous seasons. There is not evidence that this strain is more dangerous than previous H3N2 strains. It is not really a "Super Flu". Actually, the most severe flu season this decade was the 2024-2025 season with activity levels, hospitalizations, and deaths exceeding previous years. Yet, vaccination rates are down this year.
Best protection: wash hands, avoid large crowds and get vaccinated. Even in a mismatched year like this one, the vaccine still provides protection and is worth getting.
