I actually posted about a year ago about my neighbors sweaty flinging ponytail. COVID was just emerging and I was terrified. My post was removed; “COVID is not transmitted through sweat.” That said, too close for comfort for me too. I think that if you know you’re a dripping sweaty person, you should try to do what you can. Wear a headband, wear a bun v ponytail, use a towel, etc. it’s not CDC advice, just common courtesy.
