Will contact with patients necessarily lead to infection in COVID-19? Is it intimate contact with the same shopping mall?

1 Will you be infected after contact with patients in COVID-19? Not necessarily.

For example, medical staff who treat patients in COVID-19 need to contact patients in COVID-19, but they take corresponding protective measures, such as wearing masks, protective clothing, washing hands after contact, disinfection and so on. And there is almost no probability of being infected with the virus. However, if you contact patients in COVID-19 without taking protective measures, the chances of infection are very high if you contact them for a long time, and the worse your self-resistance, the more basic diseases you will have.

2. Is it contagious to wear a mask away from the patient 1 m in COVID-19? Wear a mask correctly and keep a distance of one meter. The possibility of contracting COVID-19 virus is very low.

Novel coronavirus is highly contagious and can be transmitted through respiratory tract through droplets. After wearing a mask, the probability of infection is usually greatly reduced. For example, wearing surgical masks or medical N95 masks can effectively protect against COVID-19 infection, and at the same time keep a long communication distance to avoid droplets or direct contact with infection.

If you wear unqualified masks, such as ordinary masks or smog masks, it is generally impossible to stop the spread of the virus and there is still the possibility of infection. In addition, if the mask is worn upside down, the mask is not worn tightly to cover the nose and mouth, and the mask is wet, which reduces the anti-pollution effect. It may also cause infection.

Is it intimate contact with the same shopping mall? It depends on the contact situation and whether there are protective measures.

Judging whether a person and COVID-19 patients are close contacts mainly depends on two aspects: first, individuals should have close contact with COVID-19 infected people; Second, close contacts have not taken effective protective measures, such as not wearing effective protective masks.

Therefore, if all the confirmed cases in COVID-19 have been to the same shopping mall, but they all wear effective protective masks and are far away, then according to the judgment of field epidemiological investigators, they are not close contacts. On the contrary, they have close contact with people infected with COVID-19 virus, such as living and working in the same closed environment, having dinner and entertainment, but they have not taken effective protective measures.

Close contacts can detect COVID-19 infection in a few days, and usually COVID-19 can detect it in 1- 14 days.

First of all, close contacts will only increase the risk of contracting COVID-19 virus. Such people need to take medical isolation observation measures as soon as possible, and they may not be infected with COVID-19 virus.

Secondly, assuming that close contacts are infected with COVID-19, everyone's physical condition is different. After being infected, the replication ability of the virus in the body is different. Most of them can detect nucleic acid positive within 3-7 days after contact. A few people are in good health and infected with less virus, so it is difficult to find out the virus at first. It may take 10- 14 days to detect nucleic acid positive, so the close contacts of COVID-19 infected people are generally.
