STD Awareness: The HIV Epidemic at Home

Posted on by

In the United States, we understand HIV — the virus that causes AIDS — using a common narrative, one that gives us the impression that its deadliest chapters belong in decades past or distant places. It goes like this:

The disease emerged in the 1980s, cutting down young gay men in their primes and blindsiding scientists as they scrambled to unravel the virus’ mysteries. While AIDS initially whipped up mass hysteria among the general public, LGBTQ folks demanded equality, pushing to find treatments and a cure. AIDS activism and scientific research eventually led to the development of antiretroviral drugs, which tamed the plague by turning a death sentence into a chronic disease. Now, with the right medication, people with HIV can live long, healthy lives. The hysteria has died down, as most people realize viral transmission is preventable, and the infection is manageable.

One thing hasn’t changed, however: Just as it was in the 1980s, AIDS is still thought of as a disease of the “other.” Back then, it was a disease of gay men, a population cruelly marginalized by the general public. Today, it’s thought of as a disease of sub-Saharan Africa, where HIV prevalence is highest.

That narrative, however, doesn’t tell the whole story. Right here in our own backyards, the HIV epidemic continues to spread in the face of chilling indifference from those not affected. African-American MSM — men who have sex with men, who may or may not self-identify as gay or bisexual — have an HIV prevalence that exceeds that of any country in the world. In Swaziland, for example, 27 percent of adults are living with HIV/AIDS, but if current transmission rates hold steady, half of African-American MSM are projected to be diagnosed with HIV in their lifetime. Instead of taking this projection as a wake-up call to invest in lifesaving health policies, however, state and federal responses are poised to let it become a self-fulfilling prophecy.

Contrary to racist and homophobic stereotypes, data show that black MSM aren’t more likely to engage in risky sexual behavior, use drugs and alcohol, or withhold their HIV status from partners. So why are they burdened with higher HIV rates? The answer lies beyond mere behavior, embedded in policies and practices that disproportionately harm people based on race, sexuality, and geography.

STD Awareness: “Sounding the Alarm” Over Another Antibiotic-Resistant STD

Posted on by

In 2012, the New England Journal of Medicine ominously stated, “It’s time to sound the alarm.” What followed was a description of the evolution of gonorrhea to all antibiotics we have used to treat it, including the last ones we had left. They closed the article with a warning: “The threat of untreatable gonorrhea is emerging rapidly.”

This summer, just five years after that alarm bell was sounded, the New England Journal of Medicine’s prediction came true. Reports of untreatable gonorrhea surfaced, shared in a World Health Organization press release: “Data from 77 countries show that antibiotic resistance is making gonorrhoea — a common sexually-transmitted infection — much harder, and sometimes impossible, to treat.”

An STD most people haven’t even heard of is rapidly evolving antibiotic resistance.

So maybe we should listen when a medical journal talks about the need to “sound the alarm.”

Sexually Transmitted Diseases, the medical journal of the American Sexually Transmitted Diseases Association, did just that in an editorial called “Mycoplasma genitalium on the Loose: Time to Sound the Alarm,” which accompanied two studies detailing antibiotic resistance in a little-known STD called mycoplasma genitalium, or MG for short.

“Let me get this straight,” you might be saying. “First you’re telling me there’s an STD called MG, which most people haven’t even heard of, and now you’re telling me I already need to worry about antibiotic resistance?” Continue reading →

STD Awareness: Human Papillomavirus Grabs Headlines

Posted on by

Human papillomavirus, or HPV, is the most common STD out there — a fact made even more aggravating by the absence of a good test for it. Sure, Pap testing can detect cellular abnormalities triggered by HPV, and the HPV DNA test can find evidence of infection. But it’s not a definitive test — a negative Pap/HPV DNA co-test doesn’t rule out the possibility that you carry the virus. Ditto for the anal Pap test — which most people haven’t even heard of anyway!

There are more compelling reasons to vaccinate boys against HPV — and not-as-compelling reasons to think Gardasil could protect against skin cancer.

The lack of a good diagnostic test makes the HPV vaccine an even more valuable asset. If we can drive the virus to extinction through aggressive vaccination campaigns, our limited diagnostic abilities become a moot point. And recent headlines have given us reasons to love the HPV vaccine even more.

HPV and Men

Many people think of HPV as a women’s issue, as the virus causes cervical cancer, and for a long time, boys and men weren’t even targeted for vaccination. But HPV is everyone’s issue — genital warts don’t care what gender you are, and cancer-causing strains of HPV cause most cases of anal cancer, penile cancer, and oropharyngeal cancer. Recently, a large, first-of-its kind study published in JAMA Oncology analyzed penile swabs provided by 1,757 men to figure out how common HPV is in this population. (While there is no FDA-approved test for diagnosing male patients with HPV, scientists can still collect swabs for research purposes.)

The results: 45.2 percent of American men ages 18 to 59 carry genital HPV — for a total of nearly 35 million adult males. HPV carriers can transmit the virus to sexual partners through vaginal, anal, or oral sex — or even just rubbing genitals together, as the virus is spread by skin-to-skin contact. Furthermore, a quarter of men are infected with cancer-causing strains of HPV. And, while the female population sees a peak in HPV infections in their early 20s, men’s HPV prevalence increases with age. While 28.9 percent of men 18 to 22 years of age carried HPV, 50.8 percent of them carried it by the time they were 28 to 32 years of age, and 59.7 percent of 58- and 59-year-olds were carriers.

STD Awareness: Is Syphilis Making a Comeback?

Posted on by

men syphilisBefore antibiotics, syphilis was the most feared sexually transmitted disease (STD) out there. It was easy to get, quack cures were ineffective and often unpleasant, and it could lead to blindness, disfigurement, dementia, or even death. When we were finally able to zap infections away with drugs like penicillin, it seemed like we’d finally won the battle against this scourge. Whereas syphilis rates were highest before antibiotics became widespread in the 1940s, by 2000 we saw a low of 2.1 cases of syphilis per 100,000. At the dawn of the new millennium, many scientists thought the United States was at the dawn of the complete elimination of syphilis.

Using condoms, regular STD testing, and limiting sex partners are the best ways for sexually active people to stay healthy.

Must all good things come to an end? They shouldn’t have to, but in the case of syphilis, the Centers for Disease Control and Prevention (CDC) has announced that syphilis rates are rising, with incidence doubling since 2005. In the United States, there are now 5.3 cases of syphilis per 100,000 people, but that number is a bit misleading because it represents an average across the general population. When you break the population down by age, race or ethnicity, gender, or sexual orientation, that rate might be much higher or much lower. For example, syphilis rates are actually on the decline among women (at only 0.9 cases per 100,000), but among men it is 9.8 per 100,000. In fact, most new syphilis cases — 91.1 percent of them, to be precise — are in men, most of whom are gay or bisexual.

Syphilis is rising the most dramatically among men in their twenties, especially among men who have sex with men (MSM). While some wonder if syphilis is growing among twenty-somethings because this group didn’t live through the early era of AIDS, when HIV was seen as a death sentence and safer sex practices were more common, it might also be due to the fact that STD rates are higher among young people in general.
