Scientists have found out when COVID-19 carriers are most contagious

Coronavirus virus may remain in the body for almost a month. In one case, COVID-19 was discovered 25 days after the patient has developed symptoms.
Infected with the coronavirus COVID-19 the most dangerous in the first week when the symptoms appear. Said this yesterday, the edition of South China Morning Post, citing a study by microbiologists from Hong Kong, published on the website of The Lancet. It is based on the analysis of saliva samples of 23 patients who had confirmed COVID-19. In the morning they took a swab of the oropharynx. According to the results, the viral load in saliva from patients aged 35 to 75 years was the highest for seven days after symptom onset and then decreased.

“High viral load during the first week of the disease suggests that it can easily spread from one person to another before the patient is hospitalized,” – said one of the authors of the article and associate Professor of the Department of Microbiology the University of Hong Kong Kelvin Then.

The researchers argue that the coronavirus can stay in the body for almost a month. In one case, COVID-19 was discovered 25 days after the patient has developed symptoms.

“One-third of our patients had isolation of virus for 20 days,” said Then, adding that patients may have to stay longer in detention centers.

The media called the first infected COVID-19 in China

In mainland China, the patients remain in custody for 14 days after discharge from the hospital, and then 14 days at home. In Hong Kong, discharged patients are not required to self-isolate after discharge from hospitals, but the medical staff monitors the progress of their recovery.

Previously, scientists have figured out what blood group is more prone to coronavirus. To do this, they examined the samples of more than two thousand infected patients from the hospitals of Wuhan and Shenzhen.
