Sexually Transmitted Diarrhea Disease: Why It Is Trending and What You Need to Know

The phrase sexually transmitted diarrhea disease has been trending due to a sharp rise in sexually transmitted enteric infections (STEIs)predominantly shigellosis, caused by the bacterium Shigella. Public health agencies and infectious disease monitors have raised alarms as cases spread rapidly, increasingly fueled by extensively drug-resistant (XDR) strains that make standard antibiotic treatments far less effective.

What Is Causing the Outbreak?

While bacterial gastrointestinal infections are traditionally viewed as foodborne illnesses, several enteric pathogens transmit efficiently via direct or indirect fecal-oral contact during intimate activity.

Shigella (Shigellosis): The primary driver of the current trend. It has an extremely low infectious doseingesting as few as 10 to 100 bacteria is enough to trigger a severe infection.

Other Contributing Pathogens: Campylobacter, Salmonella, and parasites like Giardia lamblia can spread through similar transmission pathways.
The Rise of Drug Resistance: The Centers for Disease Control and Prevention (CDC) and international health authorities have documented a significant uptick in antibiotic resistance. XDR strains show resistance to frontline medications such as azithromycin, ciprofloxacin, and ceftriaxone, complicating clinical care.

How Does Transmission Occur?

Sexually transmitted enteric infections do not spread through semen or vaginal fluids. Instead, they transmit when microscopic amounts of fecal matter enter the mouth. Common transmission routes include:

Oral-anal contact (rimming).
