Frequency
United States
Prevalence of whipworm infestation is less than 0.1%, although adequate studies are quite outdated.[2] The most common areas of infection are the southern Appalachian range and Gulf coast states.[3]
International
CDC estimated 604-795 million people in the world are infected with whipworm.
The highest prevalence rates of soil-transmitted helminthes occur in sub-Saharan Africa and southern and eastern Asia.[1] As with other soil-transmitted helminthes, the prevalence is higher in tropical and subtropical regions of the world, which provide the moist, humid environment required for the eggs to mature. Due to the poor sanitation practices in the rural areas of these regions the disease is prevalent.
