First, the Omicron mutant is highly contagious; Second, asymptomatic infection creates a hidden opportunity for the virus to spread. However, the source of the epidemic has not yet been determined, but imported cold chain commodities have to be vigilant and guarded against. As long as this loophole is not plugged, the same danger is likely to appear elsewhere. We can prevent the import of foreign personnel through strict isolation and universal screening, but the prevention and control of frozen food or goods in' darkness' needs to be stricter.
How to protect yourself in an epidemic?
Minimize outdoor activities, wear masks when going out, and maintain hand hygiene.
Actively monitor health and take the initiative to measure body temperature when you feel fever. If you have suspicious symptoms, you should take the initiative to put on a mask and seek medical treatment nearby in time.
The bedroom is often ventilated with windows. Family members don't use towels, keep their homes and tableware clean, and often dry clothes and quilts.
Don't spit everywhere, wrap the mouth and nose secretions with paper towels and put them in a dustbin with a lid.
If there are no suspicious symptoms before traveling, you can travel normally. If you have suspicious symptoms, it is recommended to rest at home, seek medical treatment on the spot, and then leave after the symptoms disappear.
