Do face masks help prevent catching the flu or COVID-19?
Part of Infections, Lungs & breathing clinical trials.
This trial looks at whether wearing surgical masks when out in public can reduce your chances of getting the flu or COVID-19. If you join, you'll be assigned by chance to either wear a mask outside for 3-4 months or not wear one, and you'll be tested if you get sick.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between the ages of 20 and 49
- You do not currently wear a mask during flu season
- You are willing to either start wearing a mask when going out (or, if assigned to the no-mask group, not wear a mask) for 3 to 4 months
- You go out at least 3 days a week
- You are generally healthy with no chronic conditions like liver disease, cancer, or heart disease, and are not pregnant

This study looks at how your immune system (your body’s infection-fighting system) responds during and around the time of a flu illness. It’s meant to help researchers better understand immune changes in healthy adults and may guide future flu care.
This study evaluates a home test kit that detects respiratory infections like the flu, RSV, and COVID-19 from a simple nose swab. It helps see if the test works well when used outside a clinic.
This study looks at how your lungs and lymph nodes respond to flu infection and the nasal flu vaccine. It will help researchers understand how to create better protection against the flu.
