Recently published research shows that the re-positive rate for the SARS-CoV-2 virus in China can be as high as 15%.
Peking University, China, is conducting a research project involving Covid-19 positive patients after recovery.
The study will answer two questions: why is the patient cured again and is positive, and should the necessary measures be taken with this particular group of patients?
Wang Guiqiang, head of the Peking University Department of Infectious Diseases, a member of the National Treatment Committee for Covid-19, said that 5 to 15% of Covid-19 patients in China were positive again after recovering . ill This rate varies from region to region, while in some areas it is less than 1% positive, others are very high.
The percentage of Covid-19 patients in China who tested positive was quite high after discharge.
Therefore, with more than 78,000 Covid-19 patients recovered, the number of SARS-CoV-2 re-positive patients in China ranged from 3,700 to 11,700.
Therefore, the team emphasized that it is necessary to continue applying isolation measures to Covid-19 patients who have been discharged from the hospital for an additional 14 days to closely monitor health, reducing the risk of infection in the community.
Repeated cases are only discharged from the hospital when there are 2 consecutive negative tests with SARS-CoV-2, each sample is at least 24 hours apart.
Wang said that most of the positive patients returned asymptomatic and did not need any treatment.
Chinese experts said re-positive Covid-19 patients may be related to the sensitivity of test kits or viruses hidden deep in the lungs, leading to inaccurate test results at the time of illness. discharged person.
Another possibility involves an elderly patient or chronic disease, resulting in a weak immune system, resulting in a long-term positive virus or a return of the virus that causes a positive test result.
Previously, South Korea also announced more than 300 re-positive cases in more than 9,600 discharged patients, equivalent to 3.1%.
Recently, the WHO believes that these patients are likely to be positive because these cases are releasing what is left into their lungs as part of the recovery period.
Despite this, the WHO says more research for Covid-19 re-positive cases is needed to determine if they can infect the new strain of coronavirus to others.
Minh Anh(According to Chinadaily)
Ho Chi Minh City had 9 cases of re-positive nCoV, plus 2 cases related to the Buddha bar
Ho Chi Minh City had 3 more positive cases with nCoV, bringing the total number to 9 reinfection cases. There are 2 cases related to the Buddha Bar outbreak, patients 157 and 206.
