Is the Sport Loop Band on Apple Watch made of latex?

Here are the published materials for Watch models and bands: Wearing your Apple Watch - Apple Support

Latex is not listed in that article. Given the prevalence of latex allergies, its inclusion seems quite unlikely, in any case.

Whether this is an allergy to latex or to something else, or dermatitis, or otherwise, this is also a discussion best had with your medical provider. Skin reactions are fairly common problems that many folks can encounter with many different watches. Heat and friction and sweat will do that.

Also, from that linked article: If you have questions about wearing your Apple Watch, contact Apple Support.

Does anyone know if there is latex in the band?

I can't answer that question, but I have used disinfectant wipes to remove bacterial accumulation on the band which eliminated the rash. How to clean your Apple Watch specifically recommends...

"Is it OK to use a disinfectant on my Apple Watch?

Using a 70 percent isopropyl alcohol wipe, 75 percent ethyl alcohol wipe, or Clorox Disinfecting Wipes, you may gently wipe the exterior surfaces of your Apple Watch and your Solo Loop, Sport Band, Nike Sport Band, Ocean Band, or metal band. Don't use on fabric or leather bands. Don't use products containing bleach or hydrogen peroxide. Avoid getting moisture in any openings, and don’t submerge your Apple Watch in any cleaning agents."
