Studies say infection with the new coronavirus may not necessarily translate into complete immunity.

MEDICINE NETWORK, Oct. 14 (Xinhua) -- Analysis of the first case of new coronary secondary infection in the United States shows that infection with the virus may not translate into complete immunity, U.S. researchers said in a study published Tuesday.
study was published in the British journal The Lancet Infectious Diseases on the 12th.
at the University of Nevada, Reno, and others analyzed the first case of new coronary secondary infection found and confirmed in the United States.
reportedly, the patient was a 25-year-old man living in Nevada, USA, who was first diagnosed with the virus in April and then tested negative twice.
, the man was admitted to hospital with fever, cough and nausea and was diagnosed with the new coronavirus for the second time, with symptoms more severe than the first.
the patient has since recovered and been discharged from the hospital.
researchers believe that the case shows that infection with the new coronavirus does not necessarily ensure full immunity, nor does it indicate that the phenomenon is widespread, but that further research is needed on secondary infections.
, the possibility of secondary infection can also affect understanding of the new coronavirus immunity.
stressed that everyone should take the same strict precautions to avoid contracting the virus, regardless of whether they have been infected with the new coronavirus.
