"The term "sexually transmitted diseases" (STDs), also known as sexually transmitted infections (STIs), refers to infections that are spread primarily through sexual contact, including vaginal, anal, and oral sex.
These infections can be caused by bacteria, viruses, or parasites.

Some common STIs include:

Chlamydia: A bacterial infection that can cause discharge and pain during urination.
Gonorrhea: Another bacterial infection with similar symptoms to chlamydia.
Syphilis: A bacterial infection that can cause serious health problems if left untreated.
Genital herpes: A viral infection that causes sores and blisters on the genitals.
Human papillomavirus (HPV): A viral infection that can cause genital warts and certain types of cancer.
HIV: A viral infection that attacks the immune system and can lead to AIDS.
Trichomoniasis: A parasitic infection that can cause vaginal discharge and itching.

Many STIs do not cause any symptoms, so it is important to get tested regularly if you are sexually active. STIs can have serious health consequences if left untreated, including infertility, chronic pain, and an increased risk of certain cancers.

Safe sex practices, such as using condoms consistently and correctly, can help prevent the spread of STIs."
