Can people who recover from a bout with the coronavirus become infected again — and again?
The Japanese government reported this past week that a woman in Osaka had tested positive for the coronavirus for a second time, weeks after recovering from the infection and being discharged from a hospital.
Even the mildest of infections should leave at least short-term immunity against the virus in the recovering patient, he said. In four medical professionals exposed to the virus in Wuhan, China, the epicenter of the epidemic, a test that detects the viral genetic material remained positive five to 13 days after they were asymptomatic.The PCR diagnostic test is highly sensitive and can amplify genetic material from even a single viral molecule. As such, the test could merely be picking up fragments of the virus.
Lipsitch offered an analogy: a jam jar with mold on top. Scraping off the surface might give the impression that the jam is now mold-free, but in fact the jar may still contain mold that continues to grow. In patients infected with Ebola, the virus may persist for months in the testes or eyes even after recovery — and can infect others and keep the epidemic going.
