Chinese researchers recorded in Jun a dangerous case of asymptomatic transmission of Coronavirus Covid-19 from a 20-year-old girl to five members of her family: being a bearer of infection, she did not show any signs of a dangerous disease.
However, this is not the only such case. In the report of the Chinese Center for Control and Prevention of Diseases, records were analyzed about all registered cases of infection with the virus in China from December 8 to February 11 – 1.2 % of them fell to the share of “asymptomatic” patients.
A lot of such carriers turned out to be among the sick passengers of the sad fame of the Diamond Princess liner-322 out of 621 infected Covid-19.
In the case of a 20-year-old resident of Ujan, it turned out that the incubation period of the virus after infection lasted 19 days, although earlier, according to the observations of Chinese doctors, it ranged from 1 to 14 days. Recent studies have shown that it can last up to 24 days. However, in the USA and many countries, the duration of quarantine for arrivals from China is only 14 days.
As already known, in most cases, the disease of infected covid-19 is easy, but do not forget that the virus has already killed more than 2,200 people and infected over 76,000. Most of the sick are residents of the mainland of China, from where the virus spread to 29 countries.
