  • A new Chinese study revealed that antibodies produced by the body to attack the coronavirus fade quickly in both asymptomatic and symptomatic patients
  • These findings raise concerns about whether the illness leads to long-lasting immunity to the virus after an infection
  • The study, which involved 37 asymptomatic and 37 symptomatic patients, revealed that 90 percent of both groups had steep decline in antibodies to coronavirus within 2 to 3 months after onset of infection
  • Furthermore, 40 percent of asymptomatic patients tested negative for the antibodies within 8 weeks after they were released from isolation
  • The results also showed that in 93 percent of asymptomatic patients and 97 percent of the symptomatic patients, antibody levels dropped by more than 70 percent during the early convalescent phase (8 weeks after discharge from hospital)
