Anal swabs for COVID become mandatory to enter China
The Chinese authorities have made it mandatory for travelers to enter anal swabs for coronavirus. Special test sites have already appeared at the airports in Beijing and Shanghai.
It is reported Gazeta.ru with reference to The Times. Chinese experts consider this type of test to be more accurate than a throat or nose swab. According to a study by Chinese scientists, the COVID-19 virus remains in the rectum for a longer period.
Earlier it was reported that Russian researchers believe that the composition of the tear fluid will help in determining who has a coronavirus infection. By analysis of tears you can assess the severity of the disease.
