COVID-19–Positive Testing in Minnesota High School Fall and Winter Sports: A Guide for Sports Risk

Conclusion: Athletes competing in outdoor individual sports have less risk of a COVID-19–positive test compared with age-matched individuals in the community and indoor sports participants either wearing or not wearing masks during competition. Unmasked athletes in close proximity have the highest positive test rates, and unenforced masking is not associated with lower positive testing rates. More study is needed to understand mask effectiveness.
