A troubling study published in The Lancet Infectious Diseases warns that sexually transmitted Shigella is spreading rapidly and becoming increasingly difficult to treat. The bacteria causes severe symptoms including bloody or prolonged diarrhea, abdominal cramps, and fever. While traditionally linked to contaminated food, water, or international travel, researchers emphasize that sexual transmission is now an established route, primarily affecting gay, bisexual, and other men who have sex with men.
The geographic and chronological spread of this specific variant is alarming. Between 2015 and 2020, sexually transmitted strains grew roughly 15 percent faster year-on-year than other types and spread more than twice as far geographically. Experts note that traditional prevention methods, such as meticulous hand-washing and standard food safety measures, are simply not enough to halt this particular mode of transmission.
The primary concern for medical professionals is a sharp rise in antibiotic resistance. Over 70 percent of sexually transmitted strains are now resistant to at least one key antibiotic, compared to just 40 percent in non-sexual cases. Anyone recovering from severe diarrhea is strongly advised to avoid sexual activity until two full weeks after a complete recovery, and individuals with health concerns should consult a qualified healthcare provider or a sexual health clinic.
