Masks absolutely do work. Do you need to wear a mask inside your house? Absolutely not. Should you be forced to wear a mask around 20 year old kids? Absolutely not. Should you be forced to wear a mask to go inside a hospital and nursing homes? Absolutely.
Trump takes so much shit from the hypocritical left because of us. The pathology is no different than CNN.
Without wearing a mask, droplets travel to about 70 cm.
Wearing a mask, the bulk of droplets will travel about half the distance.
However, in both cases, there are still isolated droplets transmitted beyond 70 cm.
Mask efficiency is dynamic (not constant). It is reduced during cough cycles. The fluid dynamics and the interactions between the droplets, the filter, and the face influence mask efficiency. We show that after ten cough cycles, efficiency can drop ∼8%. The above is a conservative prediction considering that we model a mild cough incident and ten cough cycles. We should expect more significant efficiency reduction for severe coughing events, as well as when wearing a mask for a longer period.
The dosage and time of exposure to a virus affecting a human are not known and will vary across subjects. We examined 10% and 32% of droplets, which are smaller than their corresponding initial size, and found that they reduce in number during cough cycles when wearing a mask.
The diameter of the transmitted droplets is larger across cough cycles when no mask is worn.
The accumulation of droplets in the surrounding environment increases as the cough continues and is more significant without a mask.
With a mask, droplet penetration approximately reaches a mean value. Without a mask, the rate of the droplet penetration increases with cough cycles and tends to decrease after several periods.
The mask to face fitting is important. Even in the case of a tight fitting scenario, if there exist some small openings, this can lead to additional leakage of droplets around the mask, which cannot be ignored. It contributes to an additional reduction in the mask efficiency with respect to efficiency reduction induced by the cyclic behavior of the coughing incident.
By wearing a mask, it will also provide greater protection to the wearer as it blocks the droplets expelled from another subject and further decelerates the incoming jet.
The complex droplet interactions and fluid physics lead to interesting phenomena such as hot spots downstream of the mask and flow recirculation associated with buoyancy.

There is no scientific evidence that masks work in nonmedical settings.

Will your mask stop my hot man butter from hitting your eyes?
