In the past, when experts talked about how to wear masks scientifically, they basically believed that there was no need to wear masks in open outdoor areas. Therefore, when I often went shopping in the park and went shopping, I would take off my mask as long as I didn’t go indoor

have a "second transmission" phenomenon, and even if it is "stricken" outdoors where air circulation is circulating?

According to experts, the virus that is popular this time is the evolutionary branch of the Omickron mutant strain BA.5.2, with a high viral load and extremely contagious. According to relevant research reports, the basic regeneration number of this strain is 18.6. In layman's terms, on average, 1 infected person can be transmitted to 18 people during his infection period. Although air circulation in outdoor areas is relatively circulating, there is still a risk of cross-infection in the case of dense crowds.

virus is evolving stronger and stronger, and is already omnipresent. From the speeches at the press conference, we can see that we still must adhere to the overall epidemic prevention policy of "dynamic zeroing", but we must oppose a one-size-fits-all, simple and rough, and layer-by-layer work method. This puts higher requirements on epidemic prevention staff, and tests local governance capabilities. Fortunately, the virus is becoming less and less toxic, and the chance of severe illness has become very small, most of which are mild and asymptomatic.

The current situation in Guangzhou is still within the controllable range, but the situation is getting tighter. There are hundreds of new infections every day, and there are more and more areas of blocked control. As ordinary citizens, we can only protect ourselves and contribute to the "dynamic zeroing" of the city's health committee by taking practical precautions according to the requirements of the Municipal Health Commission.
