Menstrual Blood: Contagion Myths and Facts

Menstrual blood is not contagious. It consists of endometrial tissue, blood, cervical mucus, and vaginal flora. It does not transmit infectious diseases through casual contact (touching, sharing spaces, laundry).

Standard hygiene—handwashing, proper disposal of sanitary products—is sufficient. Blood-borne pathogens (HIV, hepatitis) are not transmitted via intact skin contact with menstrual fluid; universal precautions apply only in healthcare settings with needlestick or mucous membrane exposure.
