Sexually-transmitted diseases, or STDs, are infections that are caused by viruses, parasites, bacteria, and other types of microorganisms. They are spread through different means:

- sharing of contaminted drug paraphernalia

- exposure to an open wound or cut of an infected person

- an infected pregnant women to her infant during pregnancy, delivery, or while breastfeeding

- having multiple sex partners

STDs can trigger different signs and symptoms on a person who gets infected. Here are the most common ones:

Sores - these may appear on the mouth, anus, penis, or vagina.

Rash - this may pop up on the palms or soles or around the genital region.

Pain when urinating - STDs can affect the urethra so a person who is suffering from one may experience pain when passing urine

Pain when having sex - this happens to females who contract STDs

Odd genital discharge - if you notice any yellowish, greenish, brownish, reddish, or other unusually-colored discharge cmoing out of your penis, vagina, or anus, you might want to get tested for an STD as soon as possible.
