‘Double masking’ not very effective: study – PerthNow
Researchers have used Japanese supercomputer simulations to show wearing two non-woven masks only slightly increases effectiveness in blocking viral spread.
Wearing two masks gives limited benefit in blocking viral spread compared with one properly fitted mask, Japanese supercomputer simulations show.
The findings in part contradict recent recommendations from the US Centers of Disease Control and Prevention that two masks were better than one at reducing a person’s exposure to the coronavirus.
Researchers used the Fugaku supercomputer to model the flow of virus particles from people wearing different types and combinations of masks, according to a…
