People are 'asymptomatic' when they test positive for COVID-19 without having shown any symptoms. The WHO says it's unclear how many transmissions happen from these asymptomatic cases Asymptomatic means a person has been infected by the virus, but does not feel sick or develop any symptoms.

After an asymptomatic infection, would someone still have antibodies against SARS-CoV-2 in their blood? Most people are developing antibodies after recovery from COVID-19, likely even those without symptoms. It is a reasonable assumption, from what scientists know about other coronaviruses, that those antibodies will offer some measure of protection from reinfection Diagnostic testing is intended to identify current infection in individuals and is performed when a person has signs or symptoms consistent with COVID-19, or when a person is asymptomatic but has recent known or suspected exposure to SARS-CoV-2. Examples of diagnostic testing include evidence on transmission from symptomatic, pre-symptomatic and asymptomatic people infected with COVID-19.
