COVID-19: What is the risk of reinfection?

A few studies have assessed immunologic changes during and after a COVID-19 infection. Some results have suggested that neutralising antibodies are protective. At the ERS 2020 Congress, Prof. Peter Openshaw (Imperial College of London, UK) reviewed some immunological considerations from recent COVID-19 studies [1]. “What we know about this virus is just changing from hour to hour,” said Prof. Openshaw. A few initial studies from China have shown a neutralising antibody response to SARS-CoV-2 in a patient cohort that recovered from COVID-19 [2]. The results suggest that there is more antibody production in patients with severe disease. Unfortunately, asymptomatic individuals have a weaker immune response to SARS-CoV-2 infection, as shown by a Chinese study in 37 asymptomatic individuals [3]. This study assessed the clinical features and immune responses of asymptomatic patients with a SARS-CoV-2 infection and found that 81.1% of the 37 asymptomatic particip...
