Patients who recover from novel Coronavirus infections may lose their immunity to re-infection within months, according to research released on Monday. A team led by researchers from King's College London examined the levels of antibodies in over 90 confirmed virus patients and how they changed over time.

Blood tests showed even individuals with only mild COVID-19 symptoms mounted some immune response to the virus. Of the study group, 60 percent showed a "potent" viral response in the first few weeks after infection.
