How are asymptomatic infected individuals identified?

In daily life, many news reports frequently mention asymptomatic carriers, causing concern among many people. So how are asymptomatic carriers identified?

How Are Asymptomatic Carriers Identified?

Asymptomatic carriers are generally detected through nucleic acid testing. Currently, if you have visited or had contact with individuals from epidemic areas, you can usually go to the hospital for routine nucleic acid testing. In fact, you may not have any obvious clinical symptoms. However, if the nucleic acid test result is positive, it generally indicates that your body has been infected with the novel coronavirus. During periods of high transmission, it's best to reduce outings. When going out is necessary, wear a mask and strengthen protective measures, which typically helps reduce the risk of contracting the novel coronavirus.

Methods for detecting asymptomatic carriers include the following: First, when a person has had close contact with someone infected with COVID-19, they are considered at high risk of infection and can be confirmed through medical examination. Second, if you have been exposed to regions where COVID-19 is widespread, self-monitoring may help identify potential infection. Third, active screening in severely affected areas may also uncover asymptomatic carriers.

Detection of asymptomatic carriers mainly relies on active surveillance and medical examinations. In particular, close contacts require medical observation and testing, and some individuals may eventually be diagnosed. Second, conducting tests in areas experiencing cluster outbreaks can also reveal asymptomatic infections. We hope this answer has been helpful to you. Wishing you good health and happiness!
