Studies Look at Healthcare Workers Infected With COVID-19 and Potential Re-infections (12/20)

By HHS/CDC - December 06, 2020

Study 1: New findings from a study of thousands of healthcare workers in England show that those who got COVID-19 and produced antibodies against the virus are highly unlikely to become infected again, at least over the several months that the study was conducted. In the rare instances in which someone with acquired immunity for SARS-CoV-2 subsequently tested positive for the virus within a six month period, they never showed any signs of being ill. 

Study 2: Among 156 frontline health care personnel who had positive SARS-CoV-2 antibody test results in spring 2020, 94% experienced a decline in antibodies at repeat testing approximately 60 days later.
