We decided it was time to revisit coronavirus basics again, after spending time on some more technical aspects. After all, as we now know the distant cousin of influenza has settled down for a long haul, and we need to be permanently prepared. So let’s get down to recapping some aspects of COVID-19 spread we may have partly forgotten by now.
Let’s Start by Revisiting the Basics of COVID Transmission
The coronavirus disease mainly spreads from infected people who breathe out air containing small particles of virus. This spread is more effective when they talk, cough, sneeze, or sing. But that is not all you need to remember when recapping some aspects of COVID-19 spread.
People within range of an infection need to be near enough to receive sufficient dose to overcome their immune system. However, those with sufficient vaccine are more likely to repel the virus because their immune systems can recognize it immediately.
Exhaled viruses remain active longer away from sunlight, and at room temperature with relative humidity below 50%. They quite soon fall to the ground, but can survive for several days on glass, some types of plastic, stainless steel, and human skin.
They die sooner on porous surfaces due to faster aerosol droplet evaporation. The materials in N95 respirator masks and surgical masks are particularly effective on this regard.
After Recapping Some Aspects of COVID-19 Spread What Now?
It follows we need to prevent the viruses reaching our noses and mouths. We have a good chance of achieving this by remaining six feet apart, or wearing face masks, or both. We should also sterilize our hands and forearms regularly. That’s because they are the most likely parts of our bodies to touch our faces.
This advice can also help prevent many other pathogen infections from viruses and bacteria. Did you perhaps notice you also have been cold- and influenza-free since you started following these precautions? That’s proof they really do work!
