The cause of the high incidence of influenza this summer

Generally speaking, the influenza is high in winter and spring season. Our province can be divided into two peaks: winter and spring and summer. There are mainly the following reasons for the high incidence of influenza this year:

First, the superior strains have changed from the previous B to type A. The infectious and pathogenicity of type A influenza is strong, which can easily lead to high intensity and large -scale popularity;

Second, the influenza has been in a relatively low state since 2020. In addition, the flu vaccination rate of flu vaccination in recent years is not high, the people's immune barriers are not strong, and the crowd is easy to increase;

Third, the period of summer influenza in our province has also occurred in May to July. Now it is also the rapid rise of summer popularity in our province.

It can be infected directly or indirectly through the oral cavity, nasal cavity, and eyes. In an environment where air is not circulated and closed, influenza viruses can also be transmitted in the form of air -soluble; in addition to the new crown virus can spread through respiratory tract droplets and close contact, spread virus pollution items, and transmit air -soluble gel.
