At the start of 2020, a small team of scientists tried and failed to convince public health organisations that COVID-19 was spread through the air we breathe. Until then, scientists thought that respiratory diseases spread through droplets, and that these droplets had a limited range.

In reality, however, breath has been a medium of transmission of most invisible things. https://newsth.live/JdTJpT
