Summary: lab testing shows a 16% reduction while real word testing shows 0.3%
Reaction to the Wuhan Engineered virus letter signed by scientists. Verses constant claims that all the countries of the world are towing the line with masks. Just because everybody is running off the cliff doesn’t make it true. Second claims the motive of the situation. Low risk of people dying wearing masks. High reward convincing everybody that Trump is dumb and people should wear masks.
science on masks
Randomized controlled study of masks with covidit spread equally between both groups.1 month of study where 4862 people split evenly to wear and not wear masksof that 42 participants (1.8%) in the mask group and 53 (2.1%) in the control group, became infected. That is a difference of 0.3 percentage point.When this analysis was repeated with multiple imputations, it yielded similar results.These results show no statistical significance between a group that wears a mask and a group that does not.Reference: Effectiveness of Adding a Mask Recommendation to Other Public Health Measures to Prevent SARS-CoV-2 Infection in Danish Mask Wearers

A study looking at health care workers during the covid outbreak found that there is a 4% infection rate. Double the normal person infection rate as listed aboveReference:Risk of COVID-19 in health-care workers in Denmark: an observational cohort study

this is consistent with previous studies of air born virus transmission with and without masks. Reference:

Conclusion. Covid is not a special case when it comes to masks and the spread of other air born viruses.
