There are about 40 species of fungus that can cause ringworm in humans, but the most common belong to three genera. Trichophyton is the most common cause of ringworm in humans. Microsporum is the most common cause of ringworm in pets, but it can be transmitted to humans.
Health Disparities. Healthcare disparities refer to differences in access to or availability of facilities and services. Health status disparities refer to the variation in rates of disease occurrence and disabilities between socioeconomic and/or geographically defined population groups. [Both definitions are from the 2009 Medical Subject Headings (MeSH).]
The National Cancer Institute (NCI) defines cancer health disparities as adverse differences in cancer incidence (new cases), cancer prevalence (all existing cases), cancer death (mortality), cancer survivorship, and burden of cancer or related health conditions that exist among specific population groups in the United States.
