COVID-19 'Super Spreaders' Quickly Fill Room With Virus -- But Masks Help.

[2greys]

Face masks can help prevent the spread of COVID-19 among folks trapped in a room with an infected "super spreader," a new Swiss study claims.

Most infected people with a typical COVID viral load don't flood the air with coronavirus-infected respiratory droplets, and the risk of catching the virus from them tends to be low, estimates show.

But a severely infected person who's coughing frequently can fill a poorly ventilated room with as many as 7.4 million copies of the coronavirus for every cubic meter of air, according to researchers Michael Riediker and Dai-Hua Tsai, from the Swiss Centre for Occupational and Environmental Health in Winterthur.

Good reason to continue avoiding a poorly ventilated room.

Yes I agree, it is the onset of winter when folk rush to be indoors because it is wet and cold where my concern lays. Okay if it is your own home, but for most, especially whilst at work, it is beyond their control.
