Chlamydia is the most common sexually transmitted infection (STI) in the United States, particularly among teens and young adults. It is caused by bacteria and can be treated with antibiotics. If left untreated, chlamydia can make it difficult for a woman to get pregnant. Gonorrhea is another common STI that can be treated with the right medication.
If left untreated, it can cause very serious health problems. Viral hepatitis is the leading cause of liver cancer and the most common reason for liver transplants. Genital herpes is a common STI, but most people infected don't know they have it. While there is no cure, there are medications available that can prevent or shorten outbreaks and make it less likely to transmit the infection.
Sexually transmitted diseases (STDs) or sexually transmitted infections (STIs) are usually acquired through sexual contact. The bacteria, viruses, or parasites that cause STDs can be transmitted from one person to another through blood, semen, or vaginal fluids and other body fluids. It is important to recognize symptoms and get tested to protect yourself and your partner. Fortunately, all of these common STDs can be treated and most can be cured.
Chlamydia is the most commonly reported STD in the U. S., spread mainly through vaginal or anal sex, but also through oral sex. Sometimes, you'll notice a strange discharge from your vagina or penis, or pain or burning when you urinate. But only about 25% of women and 50% of men have symptoms. Gonorrhea is easily treated with antibiotics.
Syphilis is a complicated disease with four stages. In the primary stage, the main symptom is a sore that may look like a cut, ingrown hair, or a harmless lump. The secondary stage begins with a rash on the body, followed by sores in the mouth, vagina, or anus. Symptoms usually disappear in the third stage or in the latent phase. This stage can last for years or the rest of your life.
Only about 15% of people with untreated syphilis will develop the final stage. In the last stage, it causes damage to organs and nerves and can also cause brain problems. Your doctor may prescribe antibiotics to treat syphilis. The sooner you start treatment, the fewer antibiotics you need and the faster they will work. Herpes is a virus that can be transmitted through skin-to-skin contact without blisters being present. More women than men get trichomoniasis, caused by a tiny parasite that is spread through contact between the penis and vagina or between two women's genitals. Only about 30% of people with trichomoniasis have symptoms that include itching, burning, or pain in the genitals as well as a foul-smelling discharge.
It is important to repeat the test within three months after treatment even if your partner has also received treatment. Vaccines are available to prevent HPV and hepatitis B infections. More than 30 different bacteria, viruses and parasites are known to be transmitted through sexual contact.
