Different diseases have different modes of transmission. And at the same time, one disease can have multiple modes of transmission. Influenza that’s transmitted by aerosols is generally thought to be associated with a more severe illness than influenza that’s transmitted via contact or fomites.
In this video we continue on from update #10 and examine in greater detail the impact of particle size, the concentration of viral RNA in coarse and fine aerosols, and how they differ in the transmission of COVID-19.
Surprisingly, larger particles (from a cough or sneeze) contain less virus than small particles, and are less likely to penetrate into lungs. Individuals who are sick produce fine, virus laden particles during speaking and breathing that have a high viral load and can travel far down into the lungs of a susceptible individual.
