Project #79:
Viral competition and non-specific immunity between COVID-19 and non-COVID-19 respiratory diseases

  • Type: Research
  • Topic areas: COVID transmission/prevalence/non-pharmaceutical prevention

There is some thought that viruses that cause respiratory illness may compete with one another so that only one can become established in the host at a time. Further, it may be possible that respiratory illnesses other than COVID-19 may induce some immune protection against COVID-19.

This study aimed to estimate the impact of non-COVID-19 respiratory infections on the incidence of COVID-19 infection and its severity among the general population.

The exposure of interest was infection with non-COVID-19 respiratory infections. The outcomes of interest were infection with COVID-19 and the resulting outcome of COVID-19 infection.
