According to predictions from the National Bureau of Disease Prevention and Control
Currently, influenza activity in my country is on the rise.
The H3N2 subtype of influenza A accounted for over 95%.
A small amount of H1N1 influenza A was found.
It was circulating concurrently with influenza B virus.
The key change in this year's flu is the shift in the circulating strain! Last season's dominant strain, H1N1, has taken a backseat, with H3N2 becoming the predominant strain. Because H3N2 has not seen large-scale outbreaks in the past two years, the general population lacks specific immune barriers, significantly increasing the risk of infection.
It is important to note that even if the name of the H3N2 subtype remains unchanged, the viral surface antigen will continue to undergo minor variations. The strains circulating each season are slightly different from those of the previous year, making them a "familiar new enemy" to the immune system.
