Asymptomatic infected persons need to be quarantined for at least 14 days, and can be released from quarantine after the quarantine period has expired when 2 consecutive nucleic acid tests are negative. Asymptomatic patients infected with the new coronavirus may not develop the disease themselves, but they can transmit it to other people, so they need to be quarantined as well as symptomatic patients, and the quarantine period should be at least 14 days. 14 days later, a nucleic acid test will be performed, and the quarantine can be lifted if the first nucleic acid test is negative, and the second one 24 hours later is also negative. If an asymptomatic patient develops symptoms during the quarantine period, he or she is a confirmed symptomatic patient who needs to be treated appropriately and can be released from quarantine after the symptoms have resolved and consecutive nucleic acid tests are negative. If an asymptomatic infected person is diagnosed, it is recommended to fully comply with the outbreak prevention and control regulations, do well in quarantine, and seek standardized treatment by immediately reporting any uncomfortable symptoms to the relevant personnel.
