Antibiotics can make women more likely to get vulvovaginal candidiasis, also known as a vaginal yeast infection. Women who are pregnant or those who have weakened immune systems also are more likely to get this condition. Men also can get genital candidiasis. Fungal infections, especially lung infections like Valley fever, histoplasmosis and aspergillosis, can have similar symptoms as bacterial infections. However, antibiotics don’t work for fungal infections. Early testing for fungal infections reduces unnecessary antibiotic use and allows people to start treatment with antifungal medication, if necessary. Anyone can get a fungal infection, even people who are otherwise healthy. People breathe in or come in contact with fungal spores every day without getting sick. However, in people with weak immune systems, these fungi are more likely to cause an infection. You can learn more about the signs, symptoms, and treatment of fungal infections and get prevention tips by visiting CDC’s fungal diseases website and by talking with your healthcare provider.
