Sexually transmitted infections (STIs) or sexually transmitted diseases (STDs) are diseases that are generally acquired through sexual contact. The organisms that cause sexually transmitted infections may pass from person to person in the blood, semen, or vaginal or other bodily fluids.
These diseases can also be transmitted through other means, such as from a mother to infant during pregnancy or childbirth, or through sharing needles or blood transfusions.
Here are the 7 worst types of STI in order:
7.Genital Herpes Virus
Genital Herpes, caused by the herpes simplex virus (HSV type 2), is a common sexually transmitted infection (STI) that any sexually active person can acquire. In fact, more than one out of every six people aged 14 to 49 years have genital herpes. It is also more common in women than men.
Most people with the virus don’t have any symptoms. However, even without symptoms, herpes can be spread through sexual contact.
This virus may cause sores that appear on the vaginal area, penis and/or anus. You are most likely to get the virus if you touch the skin of someone who has herpes sores, blisters, or a rash. However, you can still get the virus by having vaginal, anal, or oral sex with someone who has the disease, even if that person does not have a visible sores, or doesn’t know that he or she is infected. You will not get herpes from toilet seats, bedding, or swimming pools.
The best ways to prevent getting herpes is to: avoid sexual activity altogether, be in a mutually monogamous long-term relationship, or use a latex condom every time you have sex.
6. Human Papilloma Virus (HPV)
Human Papillomaviruses (HPV) is a group of related viruses that can cause warts on different parts of your body. There are more than 200 different types, and about 40 of those affect the genitals. There are two categories of sexually transmitted HPV: Low-risk HPV, which can cause genital warts; and High-risk, which can cause different types of cancers.
HPV is contracted through oral, anal, and vaginal sex and through skin-to-skin contact. The best way to prevent acquiring the virus is to use a condom during sexual intercourse. Even though it’s not clear how effective condoms are at protecting against HPV, but they will at least protect you against other STDs.
If you have HPV, you may not ever know. In fact, the CDC estimates that almost 80 million people in the United States have the virus. Depending on the type you have, you may not have any symptoms.
However, if you have genital warts, that’s indicative of HPV. The growths tend to vary. They may be raised, pink, flat, or flesh-colored. They may also be shaped like cauliflower. You may have a single wart, or you may have several. They can also vary in size and may grow on the anus, cervix, scrotum, groin, thigh, or penis. These warts may show up weeks, month, or even years after you have sexual intercourse with a person who is infected with the virus (even though he or she may not even know they are infected).
…Other types of genital HPV are linked to cancer, including cervical cancer, cancer of the vulva, anus, or penis. If you become infected with one of these types of HPV, you may have precancerous changes in cells in the tissues without any symptoms.
A vaccine is now available to prevent HPV.
Chlamydia is another common STI that can infect both men and women. Although it is not the most dangerous STI, it is one of the most widespread infections and can lead to serious consequences if not treated properly. Anyone who practices unprotected sex can contract the infection during vaginal, anal, or oral intercourse. While men are more contractors of the virus, they usually do not have any specific symptoms. Women tend to suffer more effects.
You can contract chlamydia by having vaginal, anal, or oral sex with someone who has the disease. If you’ve had the disease in the past and were treated, you can still get it again.
Chlamydia affects a male’s penile urethra and a woman’s cervix. However, people who’ve contracted the disease can go month, or even years without showing any signs or symptoms. Symptoms may include pain during intercourse, and a discolored, thick discharge from the penis or vagina. It can also cause permanent damage to a woman’s reproductive system and make it difficult for her to get pregnant later on in life.
Aside from abstaining from sexual intercourse or remaining in a long-term monogamous relationship, using a condom during sexual intercourse may help prevent transmission.
Gonorrhea is a very common infectious disease caused by Neisseria gonorrhoae, a bacterium that can grow and multimply easily in mucus membranes of the body.
The CDC estimates approximately 820,000 new gonococcal infections occur in the United States every year. It is most prevalent among young people between the ages of 15 and 24.
Gonorrhea is transmitted during sexual intercourse, including vaginal, anal, and oral contacts. It can also be spread from mother to baby during childbirth.
Many men tend to be asymptomatic. However, symptoms in men include: urethral infection, dysuria or a white or yellow urethral discharge that usually presents one to fourteen days after infection. Complications may also include testicular or scrotal pain.
Most women are also often asymptomatic. However, when symptoms do present, they are often so mild that they are mistaken for a bladder or vaginal infection. Symptoms may include: dysuria, increased vaginal discharge, or vaginal bleeding between periods. Women with gonorrhea are at risk of developing serious complications from the infection, regardless of symptoms.
Symptoms of rectal infection in both men and women may include discharge, anal itching, soreness, bleeding, and painful bowel movements. Rectal infections may also be asymptomatic.
…People who have had gonorrhea and received treatment may be re-infected if they have sexual intercourse with a person with the disease. In order to prevent transmission altogether, use protective measures.
