After changing the calculation, China has about 1,300 asymptomatic virus infections. An estimated 18-31% of patients infected with Covid-19 here do not show symptoms.
China recorded 130 more cases of corona virus infection but there were no new symptoms on 1/4, according to the South China Morning Post.
This is the first time that this item has been added to the list of the epidemic reported daily here, following pressure from Chinese public health experts and international experts.
China’s National Health Commission said the newly announced cases brought the total number of people under medical supervision due to asymptomatic up to 1,367 people.
China said it had 1,541 people with asymptomatic virus infection on March 30, of which 205 came from abroad. 302 people were removed from this list on April 1, 2 became symptomatic cases and 130 were added.
The commission said it will regularly update the number of people infected with the virus but have no symptoms, amid many people concerned about the accuracy of Chinese data.
In addition to asymptomatic patients, there were 36 new cases of Covid-19 in China as of March 31, including 35 cases of imported cases (cases of foreign origin).
There have been 81,554 people infected with Covid-19 in mainland China since January when the country began publicizing the number of people infected.
Zhang Wenhong, director of the infectious department of Huashan Hospital, said that an estimated 18% -31% of patients infected with the virus have no symptoms.
However, Mr. Zhang added that the risk of spreading in the community by people with asymptomatic virus infections remains low.
Chinese government data shows that the number of people infected with the virus without symptoms may be as high as one-third of the positive results. This data shows that more than 43,000 people in China were positive by the end of February but had no immediate symptoms.
These cases are not taken into account with officially confirmed cases, but are placed in isolation and surveillance.
The World Health Organization (WHO) and South Korea count all cases with a positive test result as a case of infection, regardless of whether they show symptoms or not. However, the US, UK and Italy do not test people who have no symptoms, other than health workers who have long periods of exposure to the virus.
