Experts appeal to study the ratio of patients with asymptomatic crown disease

(Bloomberg, New York) The number of patients who are worried about crown disease without infection may be more than expected. Scientists have called for emergency research to determine the ratio of asymptomatic.

Iceland claims that the ratio of residents received by crown diseases is higher than any other country.Shendonato, the chief epidemiologist of Iceland, said that half of the country's diagnosis patients did not have symptoms of infection.The Sunday of the Hong Kong South China Morning Post also quoted the confidential data of the Chinese government that one -third of the diagnosis patients delayed symptoms or have no symptoms at all.

The high incidence rate of asymptomatic cases makes the efforts to prevent crown disease from spreading complicated, because many countries only detect people with symptoms.

Last month, WHO MDASH; a report from the joint visiting group of China stated that asymptomatic patients were relatively rare and did not seem to be the main virus spreader.

However, the former director of the US Food and Drug Administration Gotley Bob issued a post on Twitter at the beginning of the month that it is more and more obvious that people who infect the virus from the asymptomatic or milder than the symptoms are more than what they want.Many; this makes it more difficult to control the spread of virus.

In South Korea, more than 20 % of the asymptomatic cases reported to the South Korean Disease Control and Prevention Center have no symptoms during hospitalization.Zheng Yinjing, director of the South Korean Centers for Disease Control and Prevention, told reporters on March 16 that this may reflect South Korea's scope of testing very widely.

According to a report published last week in the New England Medical Journal, Chinese doctors found that the weeks of 18 crown patients had a weeks closely monitored. Patients, especially their nosesShortly after they had symptoms.

One of the 18 patients did not have symptoms, but the virus quantity on him was similar to that of patients with symptoms, which showed that asymptomatic or mild symptoms had the potential to spread the virus.
