What can be seen is that there is a breakthrough in the cumulative number of cured cases nationwide, and the cure rate is increasing.

So, what is the standard of cure? At present, the criteria for discharge from isolation and hospitalization in the "New Coronavirus Pneumonia Treatment Protocol (Trial Version 6)" are as follows

(1) The body temperature returns to normal for more than 3 days.

② respiratory symptoms are significantly improved.

③Pulmonary imaging shows significant improvement of acute exudative lesions.

④ two consecutive negative nucleic acid tests of respiratory specimens (at least 1 day between sampling times).

Those who meet the above four conditions can be released from isolation and discharged from the hospital. Among them, it can be seen that "two consecutive negative nucleic acid tests on respiratory specimens" is one of the four conditions. So, after 2 negative nucleic acid tests, will it come back to "positive" again?

The answer is: it is possible.

A cured patient in Chengdu tested positive for nucleic acid 10 days after discharge from the hospital

On February 19, a patient with Newcastle pneumonia who was cured and returned home to isolation in Chengdu, Sichuan province, was tested positive for nucleic acid on the 10th day after returning home to isolation, and was picked up by the family and the patient.

If this is an isolated case, the following is the data from a province in Guangdong.

Guangdong 14% of patients discharged from the hospital appear "re-positive"

Recently, in Guangzhou, 13 patients (14%) were found to have tested positive for nucleic acid during a follow-up visit to patients who had been discharged from the hospital after being cured, causing public concern.

Is a positive test after discharge a re-infection?

Can a repeat positive test infect others?

Tong Zhaohui, member of the Central Steering Group to Hubei and Vice President of Beijing Chaoyang Hospital: Recently, many patients were found in different places to be positive after being discharged twice negative. Under normal circumstances, when a patient is discharged from the hospital with a positive nucleic acid test, it is generally not called "re-infection", but there may be some patients, such as older patients, whose virus clearance from the body is delayed. So the retest is still positive, not relapse and re-infection, which is a different concept.

Tong Zhaohui introduced that close follow-up was once conducted for patients discharged from hospital cured of SARS, and it was found that the lung function basically returned to normal in the CT examination one year after the patients were discharged. And patients with newly crowned pneumonia were similar to SARS patients after discharge, and there was no difference in recovery.

He also suggested that because the physical condition of discharged patients varies, patients are advised to be more sedentary than strenuously active during discharge isolation and recovery.

Why was discharge from the hospital 20 days ago reminded that there should be 14 days of isolation and observation?

Post-discharge precautions have been added to the Novel Coronavirus Pneumonia Treatment Protocol (Trial Version 6), which requires patients to be discharged from the hospital under intensive medical observation for 14 days, with follow-up visits to the hospital and follow-up examinations, including nucleic acid testing, during the second and fourth weeks of discharge.

Tong Zhaohui, a member of the Central Steering Group to Hubei and vice president of Beijing Chaoyang Hospital, said: During the SARS period in 2003, patients were hospitalized for 21 days and required self-isolation for 1 to 2 weeks after discharge, and the new coronavirus was 85% homologous to the SARS virus; patients were weaker after discharge, and it took time to recover and improve lung function; patients were just discharged from the hospital, and their immune function was relatively low, so to avoid the secondary development of other diseases. It is also recommended that patients continue to be observed in isolation after discharge from the hospital, which is not only beneficial to their physical recovery, but also relatively safe for society and families.

What else should I pay attention to when discharged patients get along with their friends and relatives?

The new pneumonia patient was discharged from the hospital after a nucleic acid test, which in most cases was negative twice, and imaging was done at the time of discharge, so the community and family members should not treat him as a special patient. We hope that the society, units, families, relatives and friends will give more love and help him and care for him, so that his recovery will be beneficial.

Will the chances of leaving sequelae after the cure of the new crown pneumonia be lower than SARS?

Tong Zhaohui, member of the Central Steering Group to Hubei and Vice President of Beijing Chaoyang Hospital: We have been following up with some patients of SARS. They were given pulmonary function, CT, and blood gas analysis. From the follow up patients of SARS, after one year, his CT, lung function and some other indicators have basically returned to normal, and there is no difference with normal people. Now this type of patients, some of his lung imaging characteristics and from the clinical pathophysiological situation including some changes, should be said to be similar to SARS, recovery is ultimately no difference.

Reminder for discharged patients

1, patients should be discharged from the hospital or standardized isolation, minimize contact with the surrounding people, preferably in a single room isolation!

2、Masking, ventilation and hand washing continue to be maintained.

3, adequate nutrition and rest is important. It is best to rest mainly, and can be appropriate activities in the isolation area.

4, after the virus infection, the body's immunity is reduced, isolation allows us to reduce the chance of infection with other viruses and bacterial infections, so that their immunity and resistance to slowly recover.

Comprehensive collation: Medical respiratory channel, news one plus one microblog, science popularization China

Editor: Ran Reviewer: Rose As of 24:00 on February 27, 31 provinces (autonomous regions and municipalities directly under the Central Government) and the Xinjiang Production and Construction Corps reported 39,919 confirmed cases (including 7,952 severe cases), 36,117 cumulative cured cases, 2,788 cumulative deaths, 78,824 cumulative reported confirmed cases, and 2,308 existing suspected cases.

What can be seen is that the total number of cured cases nationwide has exceeded 29,000, and the cure rate is increasing.

So, what is the standard of cure? At present, the "criteria for discharge from isolation and hospitalization" in the "New Coronavirus Pneumonia Treatment Protocol (Trial Version 6)" are used, namely
