Guinea Pig developed a ringworm on humans.

I did not know you could get ringworm from a guinea pig! So sorry to hear about your pets and your little sister getting it. I hope they can get rid of it quickly! One of my friends had ringworm, she was so embarrassed by it. I felt bad for her, she didn't want to tell me what it was until I made her.I don't know much about ringworm but for some reason she had it for a full year... she had claimed she got it from bad water when she was showering? I do know, that my brother-in-law caught a ringworm infection from petting their family dog, Toby. Toby never had his shots & he was always running around outside. Who knows what he got into. I had petted him before too, but I didn't catch it, weird.
