A woman was diagnosed positive, and her husband put a plastic bag over her head to deliver water. Is this kind of protection really effective?

The woman was diagnosed positive, and her husband put a plastic bag over her head to deliver water. It was really funny to see this scene. But after the fun is over, when many people return to a rational state, they will ask: Is such protection really useful? ?

It has to be said that in fact, this method has no protective effect, and it can be said to be unnecessary and completely unnecessary. If this method can be used to block the spread of the virus or directly prevent infection, this has no scientific basis at all. If this method is really useful, why do doctors always emphasize the need to wear N95 masks or medical masks when the new coronavirus exists, while other masks are of no use. In addition, why do some doctors wear protective clothing instead of plastic bags when facing positive patients? So from this point we can analyze that covering the head with a plastic bag cannot actually block the virus, and it can be said to be of no use at all.

How should we protect ourselves if there is a positive person at home?

1. Wear a mask. If there is a positive person at home who needs care. Faced with this problem, isolation can only be achieved by wearing a mask. If uninfected personnel come into contact with items used by positive patients, their hands should be disinfected, clothes should be changed frequently, and the room should be ventilated.

2. Positive persons live alone. If there is an extra room in the home, the positive person should be quarantined immediately. It is best not to go out or leave the room unless necessary. If conditions permit, it would be better if the positive person has his or her own private bathroom. Various items for your own use should also be used separately and do not supply some items with other people to avoid cross-infection.

3. Ventilation and air disinfection. During this period, ventilation and disinfection should also be paid attention to. Many people believe that after contracting the virus, they should immediately isolate themselves and lock all doors and windows. In fact, it is right to isolate, but locking the doors and windows is not completely correct, because the indoor air is not ventilated for a long time, which can easily lead to the growth of bacteria and viruses, resulting in long-lasting physical conditions that cannot be cured.
