A few days ago, it was learned from Zhongshan Hospital Affiliated to Fudan University that the director of the hospital's infectious disease department and a member of the Shanghai New Coronavirus Pneumonia Medical Treatment Expert Group gave a detailed interpretation of the nine major issues of concern to netizens.

01 My neighbor is positive, what should I do?

First of all, don't panic. Wait for notifications from relevant departments such as the CDC or neighborhood committee. During this period, pay attention to good environmental ventilation, wear masks properly, and maintain a safe social distance. In addition, nucleic acid or antigen testing can be carried out if conditions permit.

02 How long do close contacts usually need to be quarantined?

Although the incubation period of Omicron is relatively short: as short as 1 day, 3 days on average, and 6-7 days at most, according to the national requirements, 14+7 days (centralized isolation + home medical observation) is still required.

03 How to avoid cross infection in close contact isolation points?

During the quarantine period, you should follow the arrangements 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 quarantine period, maintain a good mood and get enough sleep, and do some activities in the house appropriately, which can enhance your resistance and help fight the virus.

04 How do you know if you have contracted COVID-19?

Omicron is very different from the original coronavirus two years ago. The proportion of true pneumonia is very low. Most CT scans show normal results. Most infected people are asymptomatic, and a small number of infected people have fever symptoms. The "gold standard" for diagnosing COVID-19 is nucleic acid testing. However, ordinary citizens cannot achieve daily nucleic acid testing, so another way is antigen testing. Shanghai distributed antigen test kits to all citizens a week ago.

The advantage of antigen testing is that you can do it yourself, but the disadvantage is that the sensitivity is relatively low, especially during the first day of the incubation period and one week after the onset of the disease, its test results often show negative. However, within 5 consecutive days from 1 to 2 days after the onset of the disease, the virus is highly contagious, and antigen testing can test positive and detect cases in time. Therefore, it is recommended that you always have an antigen test 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.

05 How to prevent COVID-19 when working in the company?

At present, it is very important to wear masks, ventilate, clean your hands, and disinfect surfaces. There are many new asymptomatic infections every day, and there may be a risk of infection at any time. At this time, you must be careful whether you will be infected by your colleagues, especially when the office space is relatively small. The high-risk factor for infection during work is eating, because it is inevitable to take off the mask, so it is especially recommended that everyone must eat at different times.

06 Does Omicron have 200 side effects? Will it be fatal?

This statement greatly exaggerates its sequelae. As a viral infection, Omicron is mainly confined to the upper respiratory tract, compared with the virus type that often invaded the lower respiratory tract two years ago. As long as the patient's immune function is normal, sequelae rarely occur and can basically recover completely. Currently, more than 95% of Omicron-infected people are asymptomatic and mild, and only 3%-5% are common types. Severe and critical types are rare.

07 What drugs are used to treat Omicron?

Most cases are asymptomatic and mild, and basically no medication is needed. If you have symptoms such as sore throat, muscle aches, and fever, you can use cold and fever medicine. A very small number of people may have bacterial infections, and oral antibiotics are sufficient. For those with high-risk factors, such as elderly patients, we must focus on protecting these groups. If there is an infection, through expert evaluation, the use of Paxlovid within 5 days of onset can effectively inhibit the development of severe illness and avoid death. At the same time, traditional Chinese medicine can also play an important role. Early use in high-risk groups can effectively curb the worsening of the disease.

08 How long does it take to be quarantined after being diagnosed with COVID-19?

The patient can be discharged from the hospital if the nucleic acid test turns negative for two consecutive times with an interval of more than 24 hours. It usually takes about 2 weeks from the onset of the disease to the nucleic acid test turning negative, and the patient is basically non-contagious in the later stage.

09 What should I do with my clothes after leaving the isolation treatment center?

Some people say that they should throw it away or burn it, but this is unnecessary. At room temperature, the virus can survive on many surfaces for 1-2 days. Clothes placed in suitcases or plastic bags will no longer be contagious after a few days.

Nucleic acid testing can detect infected people as early as possible and is an important means of epidemic prevention and control.

Many friends expressed doubts: Do we need to throw away the masks after the nucleic acid test? How do we throw them away? Where do we throw them away?

It is recommended to prepare a spare mask before going for nucleic acid testing.

When waiting in line for nucleic acid testing, you must wear a mask correctly. When sampling, you can take off the mask only when the staff has done hand hygiene and taken out the sampling cotton swab to prepare for sampling. Hold the mask ear straps with both hands and put on the mask immediately after sampling and leave. If the mask is found to be contaminated, it is recommended to immediately replace it with a spare mask and throw the replaced mask into the "discarded mask special bucket" set up at the sampling point.

If you do not bring a spare mask, it is recommended that you do not reuse the mask you take off after returning home. It needs to be sealed or disinfected and thrown into the "special bin for discarded masks" set up in the community, or put into a plastic bag, seal it and discard it into other garbage collection containers.

Don’t throw away used masks casually! How to deal with them?

According to the "Guidelines for the Use of Masks to Prevent Pneumonia Infected by the New Coronavirus" issued by the Joint Prevention and Control Mechanism of the State Council for Responding to the New Coronavirus Pneumonia Epidemic (Epidemic Prevention and Control Group), the principles for handling masks after use are divided into two categories:

Masks used by healthy people should be disposed of according to the requirements for household waste classification;

Masks worn by suspected cases or confirmed patients must not be discarded at will. They should be regarded as medical waste and handled strictly in accordance with relevant medical waste procedures.

How to effectively dispose of used masks? One picture to understand:

Key points:

During the epidemic prevention and control period, many communities and units have set up recycling bins for discarded masks. For ordinary citizens, they can directly throw used masks into other garbage collection containers.

Citizens who have fever, cough, sputum, sneeze, or have been in contact with such people should first spray alcohol or disinfectant on the mask to disinfect the bag, and then discard it into other garbage collection containers.
