The small amount of protection is offset by incorrect use of the mask, increased touching of the face, along with a false sense of protection; leading people to come within 6 feet of each other thinking they are safe. All these negatives increase the risk of contracting coronavirus. Additionally, the inspiratory airflow study concludes that masks can increase wearers risk of personal infection. Infected people spread the virus to others.
There are no randomized controlled trials showing mask use has a statistically significant benefit for others. Countries or states with extreme mask mandates do not universally benefit compared to those without. There is one large scale randomized controlled trial proving this statistical insignificance.
we can compare the rise in infections in regions with masks and regions without masks. Weighing various estimates, we conclude that 20 days after becoming mandatory, face masks have reduced the number of new infections by around 45%.
This is a video of people coughing. Covering your mouth tightly with your elbow is a much better way to prevent droplets from spreading. Please do not cough directly into your mask, you can harm those around you. Droplets cannot pass through a solid object such as your arm.
This video demonstrates that you should always cover your mouth when you cough, and does not show the effectiveness of a large scale public mask mandate.
Cloth is not a great anti-viral barrier, but scientifically proven to greatly limit the distance respiratory particles travel.

The argument is and has been that surgical masks limit the range of expiratory respiration, offering a modicum of protection.
