COVID-19 explained very well
For a great informative article, click here. I find it interesting how viruses are considered “live” and “dead” by some scientists. Technically viruses are never alive. They by definition cannot reproduce the way a cell or bacteria can. They are strands of DNA or RNA. They hijack the reproductive machinery of living cells. Maybe “active” or “inactive” are better terms for viruses.
We also need to know what a “critical mass” of active viruses is. That is how many are needed to cause infection. That probably varies with how strong a person’s immune system is.
We will soon be getting live information on the effect of aerosols as Donald holds mass rallies and his Republican National Convention disregarding the well known common sense for restricting the spread of COVID-19.
Sadly, the writer of the article did not promote face shields.
