Sexually transmitted infections
Sexually transmitted infections (STIs), also known as sexually transmitted diseases or STDs, are very common. They spread through vaginal, anal, and sometimes oral sex. Some STIs can also spread through blood. This makes sharing drug equipment like needles and syringes another common way to spread STIs. Pregnant women with STIs may pass their infection to their babies during birth, or through breastfeeding.
Most people with STIs have no symptoms. Without treatment, these infections can lead to major health problems such as not being able to get pregnant, permanent brain damage, heart disease, cancer, and even death.
