Does China exclude asymptomatic cases?

During the COVID-19 pandemic, some American politicians have disregarded the facts, fabricated and spread a series of lies to stigmatize China for political purposes. The so-called investigation report released by Michael McCall, a Republican and ranking member of the House Foreign Affairs Committee, was full of such prejudice and lies and based on deliberately pieced together incidents.

Rumor: China manipulated statistics throughout the outbreak and excluded asymptomatic cases when collecting data of confirmed cases.

Fact:

Asymptomatic carriers usually refer to those that have no fever, cough and other clinical symptoms, but test positive for COVID-19. The asymptomatic cases have not been listed as confirmed cases for the following reasons:

The asymptomatic carriers are divided into two groups, namely the inapparent infections and infections with no symptoms in the beginning. It is probable to call them asymptomatic infections from the view of management science.

Besides, China has reported asymptomatic infections daily and also paid great attention to the suspected and confirmed cases. Furthermore, medical observation and quarantine measures are also applied to them.
