The world's first confirmed case of a second infection with the new coronavirus has been confirmed by the University of Hong Kong

,
, Aug. 24 (Xinhua) -- A newly crowned pneumonia patient has tested positive again for the new coronavirus after returning to
from Europe.
Department of Microbiology at the University of California, May, confirmed that the patient was the second person to be infected with the new coronavirus, the first in the world.
Integrated wireless news,
01 and other
media reported on the 24th, confirmed that the second infection with the new coronavirus patient is a 33-year-old man, he was diagnosed with the new coronavirus at the end of March this year, recovered in mid-April and discharged from hospital, in early August through the United Kingdom to Spain, returned to
after the test was re-diagnosed.
Department of Microbiology at the University of California, May, confirmed that the genetic sequencing of the strains infected twice in the patient was significantly different.The team in the Department of Microbiology atUniversity said there were 24 differences in the genetic sequencing of the strain of the patient's first and second infections, and that the patient returned to
and was admitted to hospital unable to detect antibodies in his body, so it was determined that he had re-infected after rehabilitation, rather than "fuyang". This is the world's first case of second infection with the new coronavirus after rehabilitation.
team also noted that there had been evidence in the past that antibody levels in patients with neo-coronary pneumonia gradually declined months after infection.Du Qixuan, a clinical associate professor in the Department of Microbiology at
University, believes that the second case of infection indicates that the confirmed neo-coronary pneumonia may not be "immune for life" even after recovery, and that the new coronavirus may exist in the population for a long time, like influenza viruses, etc. He also said the emergence of secondary infections could also shed some inspiration on vaccine research.
, the team recommends that recoverers continue to be aware of the epidemic and consider future vaccinations for new coronary pneumonia.
