STI
INTRODUCTION
The pitfalls tied to these silent killers are very tragic. However, it has rendered many lives stagnant, full of pains and as well as truncated many destinies prematurely.
Sexually transmitted infections (STIs) are infections that are passed from person to person through sexual contact. HIV is an STI. There are more than 25 other STIs that are mainly spread by sexual contact such as vaginal, anal, and oral sex. Globally, the World Health Organization (WHO) estimates that more than one million people get an STI every day.
Sexually transmitted diseases (STDs) are often used interchangeably with “STI,” they are not exactly the same. A “disease” is usually an obvious medical problem with clear signs and symptoms. “Infection” with an STI may or may not result in disease. This is why many individuals and organizations working in health are moving toward using the term “sexually transmitted infection” rather than “sexually transmitted disease.” Most people with STIs do not have any symptoms and therefore often do not know that they can pass the infection on to their sexual partner(s).
Once the treatment is played down upon, STIs can cause serious health problems, including cervical cancer, liver disease, pelvic inflammatory disease (PID), infertility, and pregnancy problems. Having some STIs (such as chancroid, herpes, syphilis, and trichomoniasis) can increase your risk of getting HIV if you are HIV-negative and are exposed to HIV. People living with HIV may also be at greater risk of getting or passing on other STIs. When people living with HIV get STIs, they can experience more serious problems from them or find it more difficult to get rid of these infections.
The US has the highest rate of STIs in the resource-rich world. In the US, about 20 million new infections occur each year. More than half of these occur among young people (15-24 years old), even though that age group accounts for only a small proportion of all sexually active people. The US Centers for Disease Control and Prevention (CDC) reports that the number of people who get chlamydia, gonorrhea, and syphilis (the three nationally reportable STIs) is increasing in most years.
There are several reasons why teenage girls and young women are more at risk for STIs. First, the cervix (passage between the vagina and womb) in young people is lined with cells that are more likely to become infected with STIs. Second, teenagers and young adults may have problems getting the information and supplies they need to avoid STIs. They may also have trouble getting STI prevention services because they do not know where to find them, do not have transportation to get there, or cannot pay for them. Even if teenagers and young women can get STI prevention services, they may not feel comfortable in places designed for adults. They may also have concerns about confidentiality.
Teenage girls and women of color have some of the highest rates of STIs, especially for chlamydia and gonorrhea. High rates of STIs among women of color are the result of several factors, including higher rates of poverty, less access to health care, and an already high rate of STIs in communities of color. Because there are more people with STIs in some communities, this increases a woman’s vulnerability to getting an STI each time she has sex, because potential sex partners within her community are more likely to have an STI.
Regardless of race or age, less than half of those who should be tested for STIs receive STI screening. This is especially important for women, since women suffer more frequent and more serious complications from STIs than men.
Many STIs have no symptoms but can still be passed from person to person. A lot of people who have an STI do not even know it. They may be healthy, and still have an STI. It is not possible to tell a person has an STI just by looking at them. The only way to know for sure is to get tested – to have regular sexual health screenings by your health care provider. In the US, you can find an STI screening site in your area here.
While many people with STIs show no signs or symptoms of their infection, when there are signs of STIs, they are most likely to be in the genital area. The genital area in some people, including cisgender women, includes the vulva (the area around the vagina including the lips), vagina (the opening where menstrual blood comes out), buttocks, urethra (the opening above the vagina where urine comes out) and anus (the opening where a bowel movement – “poop” – comes out). The genital area in others, including cisgender men, includes the penis, scrotum (“balls”), urethra, and anus.
Fortunately, you can reduce your chances of getting many STIs by practicing safer sex. Most STIs, though not all, can be successfully cured through treatment. For other STIs, there are effective medications that can help you manage your condition.
Types of STIs/ STDs
Chlamydia STI
Clamydia is one of the most common sexually transmitted infections (STIs). It is caused by a bacterium that exists in vaginal secretions and semen (“cum”). It can be spread by vaginal, oral, or anal sex without a condom or latex/polyurethane barrier. Pregnant people can pass it on to their babies during delivery.
Chlamydia can be successfully treated with antibiotics. Symptoms may include vaginal discharge and burning during urination, but most people do not have any symptoms. If left untreated, it can spread to the upper, internal reproductive organs (ovaries and fallopian tubes) and cause pelvic inflammatory disease (PID). PID can lead to permanent infertility, meaning that it may be difficult or impossible to become pregnant.
The CDC recommends yearly chlamydia screening for all sexually active women under the age of 25, as well as for older women with risk factors, such as new or multiple sex partners. Unfortunately, recent reports show that less than half of sexually active women under 25 are screened for chlamydia, in part because of a lack of awareness among health care providers. If you are not offered a chlamydia test, you may want to request one from your health care provider.
If you test positive and are treated, it is important that your partner receive treatment in order to prevent reinfection.
Gonorrhea STI
Often called “the clap,” this STI is transmitted by a bacterium in vaginal secretions and semen. It can be spread through vaginal, anal, or oral sex without a condom or latex/polyurethane barrier. Symptoms may include a yellowish or greenish vaginal discharge and a burning feeling when urinating. Gonorrhea can also affect the anus and the throat. Many women have no symptoms. Gonorrhea can be treated with antibiotics. If left untreated, it can cause PID and permanent infertility. All sexually active women should be screened for gonorrhea. If you test positive and are treated, it is important that your partner receive treatment in order to prevent reinfection.
Herpes STI
This STI is caused by a virus that lives in the nerves. There are two common types of herpes. Herpes simplex type 1 (HSV-1) usually causes cold sores around the mouth. Herpes simplex type 2 (HSV-2) usually causes sores in the genital area. However, it is possible to get HSV-2 in the mouth and HSV-1 in the genital area. People with herpes can have no symptoms but if they have symptoms, they are usually itchy or painful blisters. The virus is spread through skin-to-skin contact with sores, but it may also spread from the normal intact skin of a person who has herpes. Many people who have never had symptoms may not realize they have herpes and currently there is no recommended tests to look for it other than a physical exam and culture of blister. In most people, the sores come and go, but the virus stays in the body for life. Sometimes there are no symptoms because the virus is “hiding” in the nerves. Some women living with HIV never had blisters or sores before they acquired HIV, and are then surprised when they develop an “outbreak” of sores because their immune systems are weakened by HIV.
Genital HSV-2 infection is more common in women than men. In addition, women living with HIV may have more frequent herpes outbreaks that may be more difficult to treat. There is no cure for herpes, but the antiviral drugs Zovirax (acyclovir), Valtrex (valacyclovir), and Famvir (famciclovir) can reduce the number of outbreaks if taken daily, and can shorten outbreaks and make them less severe if taken as soon as symptoms begin. Valtrex has also been shown to lower your risk of passing the infection to someone else. People who are pregnant can pass herpes to their babies, so it is important to let your health care provider know if you have genital herpes and you are pregnant or planning to become pregnant.
HIV
HIV stands for Human Immunodeficiency Virus. HIV is the virus that causes AIDS. It is present in blood, vaginal secretions, semen, and breast milk. HIV can be spread through vaginal, oral, or anal sex when a condom, other latex/polyurethane barrier, or treatment-as-prevention method is not used. As many as one in seven people living with HIV in the US do not know they have the virus.
Getting tested for HIV is part of routine, regular health care in many countries. The Public Health Agency of Canada, for example, recommends that HIV testing be discussed as part of routine medical care. The CDC now recommends testing all people ages 13 to 64, unless they have already been tested. It also recommends that you get tested for HIV before beginning a new sexual relationship, regardless of your age.
The World Health Organization (WHO) makes different suggestions based on where you live. Where HIV is widespread, it recommends that HIV testing be offered to anyone who goes to a health care facility. Where HIV is less common, it suggests that HIV tests be offered to people who may be at higher risk of having been exposed to HIV.
It is important that you also get tested if:
- You have ever had vaginal, anal, or oral sex without a condom
- You have ever shared needles or syringes to inject drugs or other substances
- You are uncertain of your partner’s status, or your partner is living with HIV
- You are pregnantor are considering becoming pregnant
- You have ever been diagnosed with an STI or STD
- You have hepatitis C
- You begin treatment for tuberculosis (TB)
If left untreated, HIV can cause serious illness and death. If you test positive for HIV, there are effective medications that can help you stay well for a very long time.
When a person living with HIV is taking HIV drugs and their viral load stays at undetectable levels (not enough HIV in the blood for a test to measure), that person cannot transmit HIV to a sexual partner who is HIV-negative. Further, if you are not living with HIV, pre-exposure prophylaxis (PrEP) is a drug a health care provider can prescribe to prevent you from acquiring HIV – similar to the way daily birth control pills help people avoid becoming pregnant. These HIV treatment-as-prevention methods only prevent HIV – not any of the other STIs described in this fact sheet.
You cannot get the health care and treatment you need if you do not know your HIV status. For more information on HIV, go to the section on The Well Project website called HIV: The Basics.
Genital Warts
Genital warts are caused by viruses. HPV (human papillomavirus) is the name of a large group of viruses. Certain types of HPV cause warts on the hands or feet. Other types cause infections in the genital area that can lead to genital warts, cervical cancer, or cancer of the vulva, vagina, anus, or penis. Genital HPV is spread easily through skin-to-skin contact during vaginal, oral, or anal sex. Condoms do not entirely prevent transmission. People living with HIV are more likely to be living with HPV than HIV-negative people. People living with HIV and HPV are also more likely to develop genital warts, as well as cervical or anal cancer.
It is important to find HPV early and get treatment to prevent health problems. Regular cervical screening tests are a good way to check for HPV. There are also three effective HPV vaccines. Since the introduction of the HPV vaccines several years ago, the number of 14- to 19-year-old girls with HPV in the US has dropped by more than half. It is important for young people to get vaccinated before they have sex (before they have been exposed to HPV), since people who already have HPV may not be protected b
Syphilis STI
Syphilis STI is caused by a bacterium. It can be spread by vaginal, anal, or oral sex without a condom or latex/polyurethane barrier. The disease has several phases. While it can be asymptomatic, people who have symptoms and primary syphilis (early disease) may have pain-free open sores, called chancres, in the genital or anal area or around the mouth. The sores usually heal on their own within three to six weeks. People with secondary syphilis (a later stage of the disease) often have a rash and/or hair loss. If left untreated, syphilis can proceed to the latent stage during which it may have no visible symptoms but can cause damage to the heart, brain, and other organs. Syphilis can be successfully treated with antibiotics. Without treatment, it can hurt your body’s organs, leading to severe illness and even death. People who are pregnant can pass syphilis to their babies during pregnancy and childbirth, so it is important that pregnant people get tested for syphilis. If you test positive and are treated, it is important that your partner receive treatment in order to prevent reinfection.
Hepatitis STI
Hepatitis is an inflammation (irritation) of the liver. Some types of hepatitis are caused by viruses that exist in blood, vaginal secretions, semen, and breast milk. These include hepatitis B (HBV) and hepatitis C (HCV), both of which can be sexually transmitted. There is a vaccine to prevent HBV, but not HCV. Both can become chronic (long-term) and very serious. Because HBV and HCV often have no symptoms, most people do not know that they have the infection. If there are symptoms, they can include fatigue, nausea, vomiting, yellowing of the skin or eyes, dark urine or abdominal (belly) pain. It is important for people living with HIV to be tested for HBV and HCV and treated, if necessary. Hepatitis C can be cured. For more information, see our article on Treatment of Hepatitis C in People Living with HIV.
Pubic Lice (“Crabs”)
Pubic lice live in the pubic hair (the hair around the genitals) and can be transmitted by skin-to-skin contact. They can also be spread through infected clothes and bedding. Symptoms may include intense itching and seeing lice or eggs in the hair. Pubic lice can be treated with over-the-counter medications. However, pregnant people must use products specially designed for them. Contaminated clothes, sheets, pillowcases, blankets, and towels should be washed in hot water and laundry soap to kill lice and eggs and to prevent being infected again.
Trichomoniasis STI
Trichomoniasis STI is caused by a single-celled germ called a protozoa. It can be spread during vaginal, oral, or anal sex without a condom or latex/polyurethane barrier. Trichomoniasis is a common cause of vaginal infections. Symptoms may include a foamy, foul-smelling vaginal discharge and itching. Sometimes there are no symptoms at all. Trichomoniasis can be successfully treated with antibiotics. When a woman is infected with trichomoniasis, she and her sexual partner must both be treated, or the untreated partner can re-infect her.
Chancroid STI
Chancroid STI is caused by a bacterium. Symptoms may include genital sores, vaginal discharge, a burning feeling when urinating, and swollen lymph nodes in the groin. It can be spread by vaginal or anal sex or skin-to-skin contact with sores. Chancroid can be treated with antibiotics.
Conclusion
- It is very possible to leave a healthy life free from Sexually Transmitted infections or diseases by protecting yourself using a latex condom for vaginal and anal sex or a plastic condom if you are sensitive to latex.
- The internal (female) condom can also prevent many sexually transmitted infections
- Use condoms without lubricant for oral sex on a man
- Use latex or plastic barriers, such as a dental dam or plastic wrap, for oral sex on a woman or for oral-anal sex; use latex or plastic gloves if you have cuts or sores on your hands
- Use water-based lubricants (KY, Astroglide) with latex condoms or barriers
- DO NOT use oil-based products (Vaseline, coconut or other vegetable oil, body lotions) because they destroy latex
- Do not use lubricants or condoms that contain nonoxynol-9 (N-9), which can damage the lining of the vagina or anus and increase the chances of acquiring HIV
- Wash shared sex toys (dildos, vibrators) or put on a fresh condom between users
- Know that some methods of birth control, such as birth control pills, shots, implants, or diaphragms, will not protect you from sexually transmitted infections. If you use one of these methods, also use a latex condom.
- Talk with your sex partner(s) about sexually transmitted infections and using condoms
- Talk honestly with your health care provider and your sex partner(s) about any sexually transmitted infections you or your partner has or has had
- Have regular pelvic exams and cervical cancer screenings, but remember that cervical cancer screening tests do not screen for sexually transmitted infections other than HPV
- Talk to your health care provider about having a routine sexually transmitted infection screening as part of your annual physical or gynecological exam
- Do not share needles or syringes for injecting drugs or other substances; if you do share drug equipment, be sure to clean your works
