On April 2, Professor Hu Bijie, a member of the National Novel Coronavirus Pneumonia Medical Treatment Expert Group and Director of the Department of Infectious Diseases of Zhongshan Hospital Affiliated to Fudan University, expressed concern to the public questions were answered one by one.
My neighbor is “yang”, what should I do?
First don’t panic. Wait for the notification from relevant departments such as CDC or neighborhood committee. During this period, pay attention to good environmental ventilation, standardize the wearing of masks, and maintain a safe social distance. In addition, nucleic acid or antigen detection can be performed under conditions.
2
I am a close contact and usually isolate how long?
Although the incubation period of Omicron is relatively short: as short as 1 day, on average 3 days, and as long as 6-7 days. However, according to the national requirements, 14+7 (centralized isolation + home medical observation) is still required.

How to avoid cross-infection?
During the quarantine period, you should obey the arrangement and do not leave the room without permission. Behaviors such as walking in the corridor are absolutely prohibited. At the same time, improve your immune function, especially during the isolation period, maintain a good mood and adequate sleep, and do some activities in the house properly, which can enhance your resistance and help fight the virus.

How do I know if I have Corona?
Omicron is very different from the original new crown virus 2 years ago. The proportion of true pneumonia is very low. Most of the CT tests show normal. Some infected people are also asymptomatic, and a small number of infected people have fever symptoms. Now the “gold standard” for diagnosing the new crown is nucleic acid testing. However, ordinary citizens cannot achieve nucleic acid testing every day, so there is another way to do it is antigen testing. Shanghai distributed antigen kits to all citizens a week ago.
The advantage of antigen detection is that it can be detected by itself, but the disadvantage is that the sensitivity is relatively low, especially in the incubation period on the first day of the onset and one week after the onset of the onset, its test results are often will show negative. However, within 5 consecutive days from 1 to 2 days after the onset of the disease, it is a period of time when the virus is highly infectious, and the antigen test can be positive, and the case can be detected in time. Therefore, it is recommended that you keep an antigen kit at home, and you can test it when you have doubts or when there are people with fever around you, and you can test it multiple times if necessary.

I work for a company, how can I prevent Corona?
It is very important to standardize the wearing of masks, ventilation, hand hygiene and surface disinfection. There are many new asymptomatic infections every day, and there may be a risk of infection at any time. At this time, you should be careful whether you will be infected by colleagues who work together, especially if the office space is relatively small. The high risk factor of being infected at work is eating, because it is inevitable to take off the mask, and it is especially recommended that everyone must eat at off-peak hours.
6
Omicron has 200 species Sequelae? Will it kill?
This statement greatly exaggerates its after-effects. As a viral infection, Omicron is largely confined to the upper respiratory tract compared to the type of virus that frequently invaded the lower respiratory tract two years ago. As long as the patient’s immune function is normal, sequelae rarely appear, and they can basically recover completely. At present, more than 95% of the infected people in Omicron are asymptomatic and mild, only 3-5% of the common type, and the severe and critical types are rare.
7
Omicron, what? medical treatement?
Asymptomatic and mild, basically no medication. Sore throat, muscle aches, feverSymptoms, you can use cold antipyretics. A small number of people may have bacterial infections, and oral antibiotics are sufficient. There are high-risk factors, such as elderly patients, we must focus on protecting these groups. If there is an infection, according to expert evaluation, within 5 days of onset, the use of nematevir/ritonavir tablets (Paxlovid) can effectively inhibit the development of severe disease and avoid the death of patients. At the same time, traditional Chinese medicine can also play an important role, and early use in high-risk groups can effectively curb the aggravation of the disease.
8
I have been diagnosed with COVID-19 and need to isolate how long?
The nucleic acid turns negative, with an interval of more than 24 hours, and it can be discharged twice in a row. It is usually about 2 weeks from the onset of the nucleic acid to negative, and the latter stage is basically non-infectious.
9
Out of the isolation treatment site, clothes How to deal with it?
There is talk of throwing away or burning, which is unnecessary. The virus can survive on many surfaces for 1-2 days at room temperature, and the clothes are put in suitcases or plastic bags, and they are no longer infectious after a few days.
