Hi and welcome

Please have your guinea pig seen for ringworm (aggressive fungal skin infection) by a vet tomorrow.
Be aware that ringworm is the single most transmittable issue between species, including other pets and humans. Good hygiene and a vet grade disinfectant is ideally also effective against ringworm spores (which can stay alive for up to 18 months) is absolute key! Please follow the tips in our guide. They have been learned the hard way; that is why they really work!
Please do not home treat on spec; it can easily cost a you a lot more in the end and make the shop only richer because they can refute any claims after the period where infection must have happened before the sale.
Please also be aware that no online place is legally allowed or qualified enough to diagnose without a hands-on examination. We can only tell you when and how soon you need to see a vet and what yo ask them.
Ringworm: Hygiene And Pictures

Since exposure and infection have happened at the shop or breeder (the time between infection and outbreak is 10-14 days), you can reclaim any vet cost from the pet shop when you present the bill together with your sales receipt within two weeks after the purchase. You can also report the pet shop or breeder to your local authorities over trading standards for selling infected children pets with a highly transmittable disease, but you need to have a valid vet diagnosis for that in order to be able to back up your claims.

Is your little one a single piggy? Please treat any companion, too, in order to prevent them coming down with acute ringworm, too. They are most likely already infected as well.

If your little girl is a single, please get her a new same sex friend or neutered boar from a better place in a few weeks when she is safe. Guinea pigs are group animals and not wired to live on their own. Sadly far too many shops still sell piggies and bunnies as singles or as companions for each other.
