Studies have shown that asymptomatic people with corona19, who have no symptoms, can spread the virus for a longer period of time than those with symptoms.

A research team at Chongqing Medical University in China compared the virus transmission period between 37 patients with asymptomatic corona19 and mild patients with a median.

As a result, asymptomatic patients were 19 days, about a third longer than those with mild symptoms.

The duration of the virus spread in one asymptomatic infected person reached 45 days.

However, the researchers say the virus does not necessarily lead to other people's infections.

The level of antibody retention in asymptomatic corona19 was significantly lower than that of asymptomatic.

All 37 asymptomatic patients analyzed by the team had antibodies, but their antibody levels were only 15% of those with symptoms.

The degree of loss of antibodies after cure was also found to be much more severe in asymptomatic patients.

Researchers say more than 40% of asymptomatic patients have already lost their antibodies before they are discharged.

This means that the asymptomatic immune response is weaker.

Academia also claims that there are asymptomatic corona19 infections.

More than 80% of those infected were asymptomatic on an Antarctic sailing cruise ship in March, when Corona19 was infested.

Florida health officials say the surge in corona infection is related to asymptomatic people.

Current Corona19 response and patient care focuses on symptomatic infections.

Researchers at Chongqing Medical University said they needed to extend the corona19 control policy, such as establishing a social distance, expanding corona19 tests, and strengthening hygiene to respond to asymptomatic patients.

The findings were published in the medical journal Nature Medical.
