correctly worn FFP2- Masks reduce the risk of contracting the coronavirus by seventy times. This is what the scientific task force writes in its latest status report.
According to a laboratory study, the risk of Sars-Cov-2 transmission within 20 minutes in a certain exposure situation is With a correctly worn medical mask 10 percent, with an FFP2 mask on the other hand only 0.14 percent, according to the epidemiological assessment of the situation.
Because the study authors assume that that the probability of infection in daily life is 10 to 100 times lower, this is 0.1 to 1 percent with a medical mask, but only 0.001 to 0.014 percent with an FFP2 mask.
Especially in situations with increased exposure, correctly worn FFP2 masks would offer additional protection. Since breathing is impaired more than with a medical mask, the FFP2 masks are particularly useful in situations with no or only light physical activity, such as in public transport or at public events.
