Skal man tro på dette nå da?

Medical or surgical masks

Ten studies took place in the community, and two studies in healthcare workers. Compared with wearing no mask in the community studies only, wearing a mask may make little to no difference in how many people caught a flu‐like illness/COVID‐like illness (9 studies; 276,917 people); and probably makes little or no difference in how many people have flu/COVID confirmed by a laboratory test (6 studies; 13,919 people). Unwanted effects were rarely reported; discomfort was mentioned.

N95/P2 respirators

Four studies were in healthcare workers, and one small study was in the community. Compared with wearing medical or surgical masks, wearing N95/P2 respirators probably makes little to no difference in how many people have confirmed flu (5 studies; 8407 people); and may make little to no difference in how many people catch a flu‐like illness (5 studies; 8407 people), or respiratory illness (3 studies; 7799 people). Unwanted effects were not well‐reported; discomfort was mentioned.

Å bruke munnbind har to funksjoner: 1.Beskytte bæreren fra andres virus. 2. Beskytte andre fra bærerens virus. Her virker det som om de kun har sett på 1.

Totalbeskyttelsen er summen av alle enkelttiltak som munnbind, hoste/nyse i albuen, vaske hendene ofte/grundig osv osv. Selv om en faktor ikke betyr så mye, må vi ta med det som er mulig for å oppnå best mulig totalbeskyttelse.
