Living with Covid-19
Covid-19, also known as Coronavirus is invisible to the naked eye. That's one of the reasons it is so difficult to protect against. It is also airborne, that is, it is transmitted in the air that we all breathe. It is a respitory virus, so people who have the virus, have it in their lungs, and nose and wind pipe area, so that every time they exhale, they are pumping the virus into the air around them. When they sneeze or cough they pump larger amounts of the virus into the air around them at much higher speeds and greater concentrations that travel further. Thus, people who are exercising and breathing heavily are putting much more virus into the air around them than are people who are still or not moving, or moving slowly.
