STD Awareness: The Surprising Sexual Transmission of Non-STDs

What is a sexually transmitted disease, or STD? If someone catches their partner’s cold during sex, is that cold an STD? According to the Office on Women’s Health, an STD is “an infection passed from one person to another person through sexual contact.” Unless the cold was passed through sexual contact, rather than mouth-to-mouth contact, it would not be considered an STD. Others say that, for an infection to be considered an STD, its sexual transmission must make it significantly more common in the population. So, a disease like the common cold would probably be just as common even if people never had sex.


MRSA, meningitis, and the virus that causes pinkeye can be transmitted sexually.


However, there are some infections, such as hepatitis C or bacterial vaginosis, whose status as official STDs is controversial. While researchers argue with one another over where to draw the line between an STD and a non-STD, let’s take a look at some bacteria and viruses that can be transmitted sexually, even though they’re not officially categorized as “STDs.”

You’ve probably heard of MRSA, which is pronounced “mersa” and stands for methicillin-resistant Staphylococcus aureus — a strain of bacteria that is resistant to every antibiotic in the penicillin family, as well as others. S. aureus, or “staph” for short, is the same bacteria responsible for TSS, or toxic shock syndrome, which has most infamously been associated with the use of highly absorbent tampons. But mostly, staph is a common cause of skin infections, which could be deadly in the pre-antibiotic era, but these days usually don’t raise too many eyebrows.

Unfortunately, with the emergence of MRSA, which is difficult to treat with the usual drugs, we might once again have to worry about minor skin infections blossoming into life-threatening conditions. Additionally, MRSA has found a way to hop from person to person via sexual contact, and sexually transmitted MRSA has been documented in both heterosexual and MSM (men who have sex with men) populations. Untreated, it can lead to a form of gangrene in which tissue blackens as it dies. Continue reading

STD Awareness: Is There an STD That Causes Maggots?

Update: In November 2014, another video of a maggot infestation in a woman’s genitals went viral. Many astute readers clued us in to some of the locations of this viral video, but after reviewing the websites, I declined to include an updated link because I found them to be pretty misogynistic and exploitative. The message remains the same, though — yes, it’s possible to get maggots in a vagina; no, it’s not directly caused by an STD; and no, it’s definitely not caused by a “superbug” strain of any STD. Continue reading to get the scoop on how maggots actually can infest genitals, and what we know about their connection to STDs.

Maggots grow up to be flies.

Maggots grow up to be flies.

Over the past couple of weeks, I’ve been confronted by two mysteries. The first was a collection of search terms that led curious Web surfers to our blog. Take a gander at them and see if you can tell why they raised my eyebrows:

  • new std that causes maggots
  • what is the new std superbug that causes maggots
  • stds that cause worms

There were dozens of similar searches leading to this blog, enough to make me take notice — and dig around.


Maggots infesting your genitals isn’t something you need to worry about.


First, the obvious: I Googled “STD maggots” and looked at what came up. While there was absolutely nothing to be found in the legitimate news media, there was a proliferation of recently published stories on websites that I’d never heard of, all containing the same unsourced viral video of someone removing maggots from someone else’s vagina. (Actually, I could only find stills — none of the websites I looked at had functioning video. Not that I was hugely motivated to find one that did.)

The accompanying articles described a female patient with a sexually transmitted disease (STD) said to be called “sex superbug,” an antibiotic-resistant bacteria, which caused maggots to grow in her vagina. While there is no STD formally called “sex superbug,” the original author was probably referring to antibiotic-resistant gonorrhea, which is caused by a strain of bacteria called Neisseria gonorrhoeae that has evolved resistance to the drugs we use to kill it. Someone would have to track down the video’s source, however, to confirm that the subject actually suffered from gonorrhea in addition to the infestation of maggots. Continue reading
