South Korean studies have found that patients with asymptomatic new crowns carry levels of pathogens that are comparable to those with symptoms.

Earlier, researchers pointed out that asymptomatic people with neo-coronary pneumonia can also transmit the virus to others,media BGR reported. A new study in South Korea shows that asymptomatic patients develop as much viral load in their upper and lower respiratory tracts as they do in people with symptoms. Studies have also shown that some patients may be inappropriately marked as asymptomatic because they may develop symptoms after the initial PCR diagnosis. “Isolating asymptomatic patients may be necessary to control the spread of SARS-CoV-2,” the researchers said. “

South Korean studies have found that patients with asymptomatic new crowns carry levels of pathogens that are comparable to those with symptoms.

Researchers at Shuntianxiang University School of Medicine published their findings in the journal Internal Medicine of the American Medical Association. The team observed 303 people between March 6 and March 26, who were placed in institutional isolation after outbreaks of religious groups in different cities. Two thirds are women, ranging in age from 22 to 36. Of these, 193 patients developed COVID-19 symptoms, while 110 were counted as asymptomatic at the first PCR test. In the latter group, 21 people ended up with symptoms.

The patient is observed during isolation and is regularly tested after the eighth day to determine whether a person can leave the isolation. The researchers found that the genetic material values of the upper and lower airways returned by the samples were comparable. Doctors concluded that it took 13 to 20 days for a patient to start developing symptoms. Asymptomatic carriers cleared the virus within an average of 17 days, while patients with symptoms tested negative for the first time after 19.5 days.

Because patients live in the same facility to prevent the spread of the virus, the researchers were unable to determine whether asymptomatic carriers would infect others. But there is no reason to believe that they will spread the virus more easily. The researchers concluded that “isolation of asymptomatic patients may be necessary to control the spread of SARS-CoV-2”, given the high viral load found in asymptomatic patients. They also noted that their findings “provide biological justification for the reports of transmission by such asymptomatic people.”

Other studies have shown that asymptomatic people may not report any symptoms, but their bodies still show the effects of the virus. And we’re constantly seeing research and reports that asymptomatic patients can infect others. The scientists in the study also found another potential problem: the way COVID-19 patients are labeled worldwide. Not all asymptomatic people remain asymptomatic. Some people may not develop symptoms until a few days after diagnosis, as in this study. More research is needed to determine just how infectious patients asymptomatic COVID-19 are.
