Sexually transmitted infections are on the rise: Should you worry?

In 2018, the number of bacterial sexually transmitted infections (STIs) reported in the United States reached an all-time high. This is worrisome for many reasons. Having an STI can raise risks for HIV, infertility, pregnancy complications, and infant death. Fortunately, all of these outcomes can be avoided if people receive appropriate treatment.

What are STIs?

STIs are illnesses caused by microorganisms passed between people during sex. An STI can affect anyone who is exposed to it. Syphilis, gonorrhea, and chlamydia are the most common bacterial infections. Trichomoniasis, a protozoan infection, is also diagnosed frequently in women (men who are affected almost never have symptoms).

A number of viruses can be sexually transmitted, including herpes simplex virus (HSV), human papilloma virus (HPV), HIV, hepatitis A, hepatitis B, and hepatitis C.

What are the symptoms of an STI?

New rashes on or near the genitals or elsewhere on the body, swollen lymph nodes, fevers, or discharge from the penis, vagina, or anus could all be signs of an STI. While many people who have STIs notice such symptoms, some STIs are asymptomatic and can only be identified by screening tests. For example, estimates suggest chlamydia affects close to three million Americans each year, yet symptoms may only occur in 5% to 30% of people. Other STIs, like Mycoplasma genitalium, may not cause symptoms and can be hard to diagnose.

Why are sexually transmitted infections increasing?

There are many reasons, including:

  • Not using barriers — such as condoms and dental dams — during sex. Although condoms can prevent transmission of most STIs, many people of all ages and genders do not use them.
  • Changing attitudes and knowledge around HIV may give some people a false sense of safety about unprotected sex. A new World Health Organization campaign (undetectable equals untransmissible, or U = U) notes that HIV is unlikely to be transmitted by a person with undetectable levels of the virus due to treatment. Similarly, HIV prevention strategies like pre-exposure prophylaxis (PrEP) may make some people feel less concerned about having unprotected sex.
  • Significant budget cuts to local and state STI programs in recent years. This has led to facility closures and fewer sites for screening. New federal restrictions on family planning organizations like Planned Parenthood, which provides sexual health care and STI screening and treatment for hundreds of thousands of Americans, make widespread access to care increasingly hard.

Who should be tested for STIs?

If you think you might have symptoms of an STI or are concerned about recent sexual contacts, it’s best to be tested. Additionally, the United States Preventive Services Task Force (USPSTF) recommends routine screening in sexually active young women, men who have sex with men, and others at high risk for STIs, including anyone who has unsafe sex or shares needles or equipment used to inject drugs, including cottons and cookers.

What else should I know about STIs and testing?

STIs can infect any mucosal tissue exposed to the infection, such as the throat, anus, rectum, and genitals. The CDC recommends checking men who have sex with men at all three sites because studies show this helps identify more infections. A recent study reviewed screening results from 2,627 women who came to a sexually transmitted diseases clinic in Rhode Island. Among women who chose to have a multisite screening test, researchers found that 19% of chlamydia and gonorrhea infections would have been missed with genital screening only.

If you have unprotected sexual contact, STI testing should include

  • the throat (for unprotected oral sex)
  • the rectum (for unprotected anal sex)
  • the penis or vagina (for unprotected penile or vaginal intercourse).

Keep in mind that STIs can also be spread by fingers and sex toys. A detailed sexual history is important to determine what sites need to be tested.

What can I do to prevent infections?

The best ways to prevent sexually transmitted infections are:

  • Talk openly about your sexual practices with your partners and health care providers.
  • Regularly test for STIs.
  • Use barrier protection — like condoms and dental dams — when engaging in oral, anal, or vaginal sex.
  • Ask your doctor if you should consider pre-exposure prophylaxis (PrEP), a daily pill that protects against HIV infection.
  • Get vaccinated against HPV. This helps protect against HPV-related cancers of the cervix, genitals, anus, mouth, and throat. Vaccines are also available to protect against Hepatitis A and B.

If you do have an STI, make sure you get appropriate treatment. Additionally, consider using expedited partner therapy, an approach where a person diagnosed with gonorrhea or chlamydia receives a prescription for antibiotics for their partner. This is allowed in most states and has been shown to prevent recurrent infections by decreasing the number of people who continue to have sex with an untreated partner.

Where does all of this leave you?

Sexually transmitted infections are preventable and treatable. Good sexual health requires talking to your partners and health care providers openly about your sexual practices, being tested at all relevant sites on the body and, if necessary, being treated promptly.

    Sexually transmitted infections are preventable and treatable but we need a serious approach towards curing it in a well manner. Sometime peoples not having a full education so they think its not possible or its impossible. But the article itself a book which must read for everyone such as men women on this planet. Thanks a lot for sharing it. Really helpful too.

    I don’t understand why the USPSTF focuses more on women getting tested than men. Women are more vulnerable than men to STDs and the ailments they can cause but it is the men they get them from. Did you know women are 4 times more susceptible to HSV-1/2 than men because of their anatomy? The lackadaisical opinion on men not getting tested just makes the spread of STDs worse and mainly for women. Why don’t men get tested regularly for HPV, HSV, chlamydia & gonorrhea? Historically men are more promiscuous and a condom doesn’t necessarily protect you from these STDs. USPSTF stance seems ridiculous and sexist and dangerous for women.

      I agree 100% ; especially but not limited to HPV. Men don’t know if they are a carrier, yet they can spread the HPV to women. Yet only women get tested. That is insanely dangerous to mostly women. This has to be changed. There are no vaccines for older women, why is that? Something is very wrong here and it needs to be changed.
