Using a study design from the past, researchers again show COVID-19 is airborne
In 1959, researchers built a facility near Pretoria, South Africa, to study the airborne route of tuberculosis transmission, replicating an experiment first done in Baltimore. With a detailed schematic of ward rooms, test and control chambers, and room exhaust fans, the researchers proved nature’s deadliest bacterium traveled through the air, meaning infectious people in one part of a building could infect others through a ventilation system.
For most people, when they come down with a typical, non-life-threatening illness, our doctors tell us to rest up and to avoid other people as much as possible. But for nursing home patients battling memory-related ailments, the act of isolating from others while as a method to recovery, creates a medical conundrum. This is because those dealing with cognitive-decline conditions desperately rely on daily social interaction to slow the rate of cognitive decline. So, you can see why the act of isolating a person in this setting, while they recover from an unrelated disease, often does more harm than good.
