What are risk factors for thrush?
Healthy adults generally do not get thrush without having some risk factors. Patients with weakened immune systems are most at risk for getting thrush. Risk factors associated with thrush include the following:
- Illnesses, including poorly controlled diabetes, HIV/AIDS infection, cancer, and dry mouth
- Taking medications such as antibiotics, corticosteroids, chemotherapy or other cancer drugs, radiation, and birth control pills
- Having an organ transplant
- Poorly fitting dentures
In general, thrush is not contagious. However, a nursing infant with thrush may transmit it to the mother's breast by contact.
