Healthcare experts determine the effectiveness of one-way masking

On April 18, a federal judge in Florida overturned the US Centers for Disease Control and Prevention’s (CDC) public transportation mask rule, removing the requirement to wear a mask on public transit in the vast majority of situations.

Even if others around them aren’t masked, some public-health experts have recommended people to continue masking on public transport services and in other crowded indoor settings as restrictions expire. Even if wearing a good-quality mask isn’t suggested for everyone in their area, people at high risk for severe COVID-19, should continue to do so. It is especially recommended for those who are immunocompromised or have chronic diseases.

This idea of wearing a mask even if no one else in the room does is called one-way masking. According to Emily Sickbert-Bennett, head of infection prevention at UNC Medical Center, one-way masking is clearly better than nothing. But it may not be as effective as universal masking. She added that a mask’s purpose is to keep the wearer’s germs confined while also filtering out other people’s germs. If two people wear masks that collect some of the particles they exhale, there will be fewer viruses floating around their shared air, and both people will be less likely to get sick.

Kimberly Prather, an aerosol expert and the chair of atmospheric chemistry at the University of California, San Diego, says that blocking the source is one of the most important things you can do in infection management. It must never be allowed in the air in the first place. If one person is unmasked and freely releasing germs, the mask of the other person bears the entire duty of protection. While fabric and surgical masks offer some protection in this situation, N95 respirators are designed to filter out practically all particles, making them the best and most protective one-way masking choices.

It all means that one masking is much better than no masking. So, people should opt for it!
