People online are touting the results of a Cochrane review to incorrectly claim that it shows masks “don’t work” against the coronavirus. But the primary conclusion of the review is that it’s uncertain from randomized controlled trials whether mask interventions in the community help slow the spread of respiratory illnesses.
Three years into the COVID-19 pandemic, few topics have become as polarizing as masks. Some people claim masks are a panacea; others say masks are worthless or worse. The evidence, however, is more complicated and nuanced — and points somewhere in between, experts told us. Reigniting the debate — and sparking misinformation about masks from both si...
One reason the Cochrane review has garnered so much attention is because Cochrane has a reputation for excellence. The group doesn’t do original research, but performs what are called systematic reviews, which summarize the collective literature on a particular question in a careful and predetermined waythat minimizes bias. This prevents someone fr...
Benjamin Cowling, an epidemiologist at the University of Hong Kong who has studied masks, said he thought the review was very similar to other systematic reviews on the topic. But he found the authors’ conclusion that wearing masks in the community “probably makes little or no difference” to be problematic. He noted that the confidence intervals fo...
One point of confusion for many people is that lab studies show masks, mostly well-fitting and high-filtering N95 respirators, are good at blocking viral particles. This is evidence that masks can in theory be quite effective, both for individuals and for larger populations. Some scientists have pushed for people to use better masks, especiallyN95 ...

Mar 1, 2024 · Generally, masks can help act as a filter to reduce the number of germs you breathe in or out. Their effectiveness can vary against different viruses, for example, based on the size of the virus. When worn by a person who has a virus, masks can reduce the chances they spread it to others.

In addition, there are other prevention strategies that you can choose to further protect yourself and others. Wearing a mask and putting distance between yourself and others can help lower the risk of COVID-19 transmission. Testing for COVID-19 can help you decide what to do next, like getting treatment to reduce your risk of severe illness ...
Oct 29, 2023 · No mask is 100% effective. An N95, for example, is named as such because it is at least 95% efficient at blocking airborne particles when used properly. But even if a mask has an 80% efficiency ...
