I'll trade a cold for Covid-19 any time!

https://www.medicalnewstoday.com/articles/a-common-cold-virus-may-help-fight-covid-19

To find out, the researchers infected cultures of human respiratory cells in the lab with either SARS-CoV-2, an HRV, or both viruses at the same time.

The cultures closely mimicked the outer layer of cells, called the epithelium, that lines the airways of the lungs.

SARS-CoV-2 steadily multiplied in the cells that the team had infected with this virus alone. However, in cells also infected with HRV, the number of SARS-CoV-2 virus particles declined rapidly until they were undetectable just 48 hours after the initial infection.

In further experiments, the scientists found that HRV suppressed the replication of SARS-CoV-2, regardless of which virus infected the cells first.

Cheers,
Tom

Well. I do understand the excitement, but with already observing the drift of the Sars-CoV-2, I'm not really sure we should force events which may result in a shift :nb)

This might be an early indicator of the rather strange phenomena of viral interference, it seems like most seasonal infections take turns at infecting the population rather than occurring together. It seems that the effects of a viral infection causes changes in the internal environment that effectively inhibits other viruses causing infection at the same time.

With all the distancing, there's no flu going around. I guess it's the same with colds.
