Sexually Transmitted Diseases

What are sexually transmitted diseases (STDs)?

Sexually transmitted diseases (STDs), or sexually transmitted infections (STIs), are infections that are passed from one person to another through sexual contact. They are usually spread during vaginal, oral, or anal sex. But sometimes they can spread through other sexual contact involving the penis, vagina, mouth, or anus. This is because some STDs, like herpes and HPV, are spread by skin-to-skin contact.

Some STDs can be passed from a pregnant person to the baby, either during pregnancy or when giving birth. Other ways that STDs may be spread include during breastfeeding, through blood transfusions, or by sharing needles.
