Traveler's Diarrhea Market to Reach USD 1.6 Billion by 2034

Traveler's diarrhea (TD) is the most common illness affecting international travelers, typically caused by bacterial pathogens such as Escherichia coli (ETEC), Shigella, Campylobacter, and Salmonella, though viruses and parasites also contribute. It affects millions of travelers annually, especially in developing regions of Asia, Africa, and Latin America.
While TD is usually self-limiting, it can disrupt travel, cause severe dehydration, and lead to complications in vulnerable populations. The growing global travel industry, coupled with increasing antimicrobial resistance, has created demand for improved preventive measures, rapid treatments, and vaccines.
