Males and females are affected equally

People age group 15-30 yrs TD is seen more frequently

Incidence can vary based on factors as→ destination→ season of travel→ length of stay→ quality of local sanitation

Poor hygiene practices in local restaurants is considered one of the biggest contributor to developing TD

Travelers from nations with an intermediate or high risk of TD had a much lower incidence rate than those from nations with low risk
