The status of many asymptomatic Covid-19 patients has been reported in previous outbreaks. In June, a study led by the Ho Chi Minh City Hospital for Tropical Diseases and the Oxford University Clinical Research Center (located in Ho Chi Minh City) reported that 43% of Covid patients -19 during a monthly outbreak. On April 3 in Ho Chi Minh City, he is asymptomatic.
Research published above Clinical infectious diseases This also warns of the risk that 2 of these patients, even without symptoms, infect another 4. The authors believe that this may be the cause of the disease that is difficult to control.
An August 21 report from the Da Nang City Disease Control Steering Committee, amid the Covid-19 wave in August-September, showed whether 172/243 people were hospitalized at the time. has symptoms.
Comments on the phenomenon of asymptomatic Covid-19 people were noticed too much, generally 3 of the last 4 cases, Dr. Truong Huu Khanh, Head of the Department of Infections – Neurology, Children’s Hospital 1, Thinks that he is happy and worried .
The first is happy patients when they are mildly ill. Also, having many viral infections but having no symptoms indicates that the virus is becoming “purer” with humans. That is the inevitable progression of diseases: the virus is trying to change itself to spread faster, causing a mild illness, because the sick person is too serious, dead or lying down, cannot go anywhere and cannot spread. for whom!
Because the sick person is mild, “healthy people carry carriers” (that is, people without symptoms) of great concern. The disease can become very serious if it affects certain people at risk, such as people with the underlying disease. People with mild symptoms often think they have a cold. People without symptoms don’t know they are sick, but they still spread germs. It is fine if you infect a healthy person, but if you go to visit a sick person or infect someone very weak with an underlying illness, it will cause serious illness.
“That is why I advise young and healthy people to still protect themselves, not subjectively, they will be healthy, the disease will be mild. Young people go a lot, they have more exposure, they are susceptible to infection. carry pathogens to risky objects at home, at work, when visiting patients … At that time great consequences will occur, even if the epidemic settles, it is not allowed to forget the mask, wash hands and other measures of protection because as long as the world remains an epidemic, the risk of an outbreak in the country will remain very high ”- explained Dr. Khanh.
