Sexually Transmitted Gut Infections: Prevention Strategies
- What: Increasing prevalence of sexually transmitted enteric infections (STEI) caused by a variety of pathogens, including bacteria, viruses, adn parasites.
- Where: Globally, with a disproportionate impact on men who have sex with men (MSM).Initial recognition of this transmission route occurred in the US (late 1960s/early 1970s).
- When: Recognition as the late 1960s/early 1970s, with a recent surge since the end of the COVID-19 pandemic.
Sexually Transmitted Gut Infections: Key Facts
What: Increasing prevalence of sexually transmitted enteric infections (STEI) caused by a variety of pathogens, including bacteria, viruses, adn parasites. These infections are becoming more drug-resistant and difficult to treat.
Where: Globally, with a disproportionate impact on men who have sex with men (MSM).Initial recognition of this transmission route occurred in the US (late 1960s/early 1970s).
When: Recognition as the late 1960s/early 1970s, with a recent surge since the end of the COVID-19 pandemic.
Why it Matters:
* Rising Drug Resistance: Many pathogens are becoming multi-drug resistant, limiting treatment options.
* Public Health Gap: STEI outbreaks often fall between traditional foodborne illness and STI surveillance, leading to overlooked transmission routes.
* Global Spread: Ease of international travel facilitates the spread of these “gastrointestinal superbugs.”
* Behavioral Driver: Infection rates are linked to behavior, not necessarily HIV or immune status.
Key Pathogens (12 recognized):
| Pathogen | Type |
|---|---|
| Campylobacter | Bacteria |
| E. coli (diarrheal strains) | Bacteria |
| Salmonella | Bacteria |
| Shigella | Bacteria |
| Entamoeba histolytica | protozoan |
| Giardia | Protozoan |
| Strongyloides | Parasite |
| Cryptosporidium | Protozoan |
| Cystoisospora | Protozoan |
| Microsporidia | Fungus |
| Hepatitis A Virus | Virus |
| Brachyspira | Bacteria |
Pathogens with Uncertain Sexual Transmission Role: Clostridioides difficile, Hepatitis E, other enteric viruses.
What’s Next:
* Improved Diagnostics: Utilizing advanced molecular testing to identify pathogens and their genetic strains for targeted treatment.
* Community Education & Testing: Increased awareness and testing programs, particularly within at-risk populations.
* integrated Surveillance: Better integration of STI and foodborne illness surveillance to capture STEI transmission.
* further Research: Continued examination into transmission dynamics and the role of behavioral factors.
