Introduction
After recovery from a novel coronavirus infection, individuals are generally no longer contagious to others. The novel coronavirus is highly infectious during both the incubation and symptomatic phases. However, in patients who have recovered, consecutive nucleic acid tests yield negative results, pulmonary lesions have been absorbed, and the body produces specific antibodies. These antibodies persist in the body for a period of time.
Novel coronavirus infection is a highly contagious disease; therefore, many people wonder whether recovered patients can still transmit the virus.
Can recovered patients still transmit the novel coronavirus?
Generally, individuals who have fully recovered from novel coronavirus infection are no longer infectious to others. The virus exhibits high transmissibility during both its incubation period and symptomatic phase. However, after recovery, patients consistently test negative on repeated nucleic acid tests, their pulmonary lesions have been absorbed, and they develop specific antibodies against the virus. These antibodies persist in the body for a certain period, conferring resistance and immunity to SARS-CoV-2—thereby preventing reinfection and eliminating infectiousness.
Nonetheless, in rare cases, some patients experience recurrence after discharge from the hospital; such individuals may retain limited infectious potential. Patients should remain isolated until confirmed negative again before resuming normal outdoor activities and social interactions.
Even after recovery, patients should continue practicing personal protective measures: wearing masks when going outdoors, avoiding crowded public places, and thoroughly disinfecting their living environment to prevent reinfection. We hope this information is helpful to you!
