Common Cold Suppresses COVID-19 Infection

There follows a guest post by Lockdown Sceptics’ regular Guy de la Bédoyère.

Just when you thought the Covid madness couldn’t take any more twists, here comes another one but you’d better brace yourself. The BBC’s Science Correspondent James Gallagher has a startling revelation that the common cold (the rhinovirus) can suppress COVID-19 because it’s so tough the SARS-CoV-2 virus gets pushed out of the way to make room for it. The news comes from the Journal of Infectious Diseases.

Here’s the summary:

Human rhinovirus triggers an innate immune response that blocks SARS-CoV-2 replication within the human respiratory epithelium. Given the high prevalence of human rhinovirus, this interference effect might cause a population-wide reduction in the number of new COVID-19 infections.

From a host’s perspective, HRV [Human Rhinovirus] infections, which are usually associated with mild disease, stimulate an antiviral response that prevents infections by more severe (and sometimes lethal) viruses such as SARS-CoV-2.
