Q. Is it possible that fleas can be transmitters of ringworm among cats?
AMY S. EUTSEY, DVM
A. Not likely. Ringworm is a highly contagious fungal infection that is readily transmitted from any contact with an infected animal. A person can transmit it on their hands or clothes from handling the infected cat and then touching another. Spores can reside in the home on any surface and without proper disinfection, one cat can get it just from being in contact with that surface. It is not uncommon for every cat in a household to eventually get ringworm if one is not extremely careful with handling the cats and isolating any infected one.
