- Researchers emphasize there are two main reasons to wear masks. There's some evidence of protection for the wearer, but the stronger evidence is that masks protect others from catching an infection from the person wearing the mask. And infected people can spread the virus just by talking.

As recently as early February, the World Health Organization stated that viral transmission from asymptomatic peoplewas likely “rare,” based on information available at the time. But a growing body of data now suggests that a significant number of infected people who don’t have symptoms can still transmit the virus to others. A CDC reportissued March 23 on COVID-19 outbreaks on cruise ships offers a glimpse of the danger. It describes how the testing of passengers and crew on board the Diamond Princess found that nearly half – 46.5% – of the more than 700 people found to be infected with the new coronavirus had no symptoms at the time of testing. The CDC explained that “a high proportion of asymptomatic infections could partially explain the high attack rate among cruise ship passengers and crew.” Dr. Harvey Fineberg, former president of the National Academy of Medicine and head of a new federal committee on infectious diseases, told CNNon April 2 that he will start wearing a mask i...
While research on the effectiveness of universal mask wearing for reducing respiratory droplet transmission is still thin, there is evidenceto support it. Research on SARS, another coronavirus, found that N95 masks were highly effective at blocking transmission of that virus. Even ill-fitting medical face masks have been found to interruptairborne particles and viruses, keeping them from reaching as far when someone sneezes. Another study determined that, while masks made out of cotton T-shirts were far less effectivethan manufactured surgical masks in preventing wearers from expelling droplets, they did reduce droplets and were better than no protection at all.
The surgical masks that doctors and nurses typically wear are designed for one-time use, while cloth masks used by the general public would likely be washed, which raises another concern. A studyfrom Nepal on cloth masks designed to protect wearers from larger particles, such as pollution or pollen, found that washing and drying practices deteriorated the mask’s efficiency because they damaged the cloth material. It is clear that urgent research is needed on the best material suitable for universal masks, their storage and care, or the creation of proper reusable masks for the public.
As an obstetrician-gynecologist and researcher, I believe that some protection for the public is better than none. A recent article in the medical journal The Lancet Respiratory Medicinestates a similar rationale. The universal use of mouth and nose covering with masks is a low-risk intervention that can only assist in reducing the spread of this terrible illness. If everyone wears a mask, individuals protect one another, reducing overall community transmission. It could even remind people not to touch their facesafter touching potentially contaminated surfaces. As the research shows, masks aren’t shields. It’s still important to help prevent transmission by practicing social distancing by staying at least 6 feet away from others in public, staying home as much as possible, and washing hands frequently and properly.

- Masks protect other people. The primary way the coronavirus spreads is from person to person by respiratory droplets produced when an infected person coughs, sneezes or talks.
- You may not realize you are contagious. It used to be that masks were recommended only for people who knew they had COVID-19, as a way to protect others around them.
- Masks can protect you, as well. A few studies suggest cloth face masks offer some protection for the wearer, but the protective perks are most obvious when everyone covers the mouth and nose.
- Masks may help the economy recover. Masks could offer an economic boon, as well. A report released by investment firm Goldman Sachs found that a national face mask mandate could serve as a substitute for lockdowns “that would otherwise subtract nearly 5 percent from GDP [gross domestic product].”
