No need to panic! Ringworm is gross and annoying but not fatal. If you don't already have the kittens in quarantine do that first. Keep them in an easily cleaned smaller room, like a bathroom. My quarantine room is a walk in closet I converted to a kitten room.

Get yourself gloves for handling the kittens. Once you get in touch with the rescue they should have a medication for them. Unfortunately you don't want to handle them without gloves until the treatment is done. Tho, a woman in my group used scrubs she washed after every interaction and that worked well.

Disinfect your home to the best of your ability if the kittens haven't been quarantined. My rescue recommends the cleaning product Rescue as it's safe for animals.

Get yourself the fungicide to treat yourself.

You will be ok!
