Can my baby catch athlete's foot in the tub if my husband has it?
Yes. Athlete's foot is caused by a fungus called a "dermatophyte," which is the same type of organism that causes ringworm and jock itch. These infections are spread by skin-to-skin contact and also by contact with contaminated inanimate surfaces, especially when there is moisture present. This is why athlete's foot is so easily spread in locations such as public pools and showers at gyms. Bathtubs in the home are also a potential source of passing infection from one person to another. And although certain individuals seem to be "immune" to these fungal infections, I would recommend your husband be adequately treated to decrease the risk of transmission to your baby
or other members of the family.
