 Novel coronavirus pneumonia 18 days after discharge, rehabilitation isolation 14 naive enough?


Recently, a novel coronavirus pneumonia in Xuzhou, Jiangsu, was released 18 days later. Previously, novel coronavirus pneumonia patients in Guangdong, Sichuan and Chongqing also recovered after 14 days of isolation.

Forenoon, novel coronavirus pneumonia, was diagnosed as a new crown pneumonia in January 23rd, and recovered after treatment. It met the discharge standard and was discharged from hospital on February 9th morning. He was placed in isolation and received 14 days of medical observation, according to media reports. He was diagnosed with fever in January 26th. On February 24, the patients and their families were sent back to the residential area by vehicles arranged by the local street office. On the 27th, nucleic acid test was performed.

As a result of his diagnosis, 65 residents from 27 households in his residential unit were required to be isolated at home for observation, and the isolation was lifted on February 9. On February 24, after the patient returned to the community, neighbors held a welcoming ceremony to congratulate him on his recovery. The reporter called Xuzhou CDC today, and the staff told the reporter that at present, the unit has been closed and isolated again.

Is 14 days isolation really enough?

As of 8:30 on February 29, 39049 discharged cases have been cured in China. The number of discharged patients is increasing every day. Is the 14 day isolation really enough? Is the 14 day isolation of discharged patients complete?

After discharge, why does the nucleic acid test of patients recover Yang?

The novel coronavirus pneumonia diagnosis and treatment plan (trial version sixth) has suggested that two suspected respiratory tract specimens are negative for nucleic acid detection (sampling interval of at least 1 days), and the body temperature returned to normal for more than three days, respiratory symptoms improved significantly, and pulmonary imaging showed obvious improvement of acute exudative lesions before isolation and discharge.

Under such a standard, the nucleic acid test of Xuzhou patients turns positive after discharge. Is the leak detected when they leave hospital?

Huang Mao told the health times that the reason for nucleic acid conversion from Yin to Yang is still in cognition, and there may be many reasons, such as the possibility that the patient is not Yin to Yang, and the previous negative examination may also be false negative. Different parts of the human body have different virus contents in different course of disease. If the throat itself has little virus, or the samples are not well sampled, or the virus load in the samples is too low, accurate results cannot be obtained. This phenomenon can be caused by the sensitivity of nucleic acid detection kit.

Can Fuyang patients infect others?

Compared with how to recover the positive value of nucleic acid, we are more concerned about whether the patients after the recovery of the positive value of nucleic acid are infectious. At the press conference of the joint prevention and control mechanism of the State Council on February 28, Guo Yanhong, the supervisor of the medical administration and Health Administration of the national health and Health Commission, said that through the monitoring, it was found that the patients with positive value of nucleic acid test did not infect others again in the follow-up visit after leaving the hospital A part of the patients turned negative again when they tested the nucleic acid of new coronavirus.

But she also stressed novel coronavirus pneumonia is a new virus, and its pathogenesis, disease profile and duration of disease need further understanding. It is necessary to further strengthen the management of discharged patients, and strengthen follow-up, health monitoring and health guidance during the implementation of 14 day medical observation. At the same time, the National Health Commission organized experts to further study the situation, and further deepen the understanding of the whole process of the occurrence, development and prognosis of the disease.

Professor Huang Mao also said that whether Fuyang patients can infect others depends on the amount of virus, the virulence of the virus and the resistance of individuals. At present, there is no report of Fuyang patients infection, which needs to be further observed.

In addition, Professor Huang Mao also suggested that the discharged patients should continue to carry out self-health monitoring for 14 days after discharge, wear masks, live in a single room with good ventilation, reduce close contact with their families, eat and drink separately, do hand hygiene well, and avoid going out. Can also do appropriate activities at home, conducive to the recovery of the body.
