Yes, it is possible to contract tuberculosis (TB) through oral sex, especially if the infected partner has genital or oral TB
. While TB is most commonly spread through airborne transmission, it can become genitourinary TB and be spread through sexual contact, including oral sex. The risk is increased by sores or cuts in the mouth or on the genitals.
How transmission can occur
Genital TB: If a person has tuberculosis in their genital or urinary tract, they can transmit the infection to a partner through sexual contact, including oral sex.
Oral TB: A person can get tuberculosis in their mouth, which can be spread through direct oral contact.
Risk factors: The risk of transmission through oral sex is increased if either partner has sores, cuts, or bleeding gums in the mouth or on the genitals.
Important considerations
Avoid pre-sexual activities: To prevent cuts and bleeding that increase risk, avoid brushing teeth or using dental floss immediately before oral sex, notes nhs.uk.
Standard STI prevention: General practices for preventing other sexually transmitted infections (STIs) also apply, as many STIs can be transmitted through oral sex.
Untreated versus treated TB: If a person has been diagnosed with TB and is receiving treatment, they do not spread the disease
