Overview
Epidemiology and Demographics
Incidence
- The incidence rate of hookworm infection was 7.5/100 person-years.[1]
Prevalence
- Prevalence of Ancylostomiasis is approximately 1 billion people worlwide.[2]
- The prevalence of ancylostomiasis in children increases with age, and typically reaches a plateau in late adolescence, whereas the intensity may continue to increase throughout adulthood.
- Ancylostoma duodenale and Necator americanus are common species, which are prevalent in tropical and subtropical countries. (Pawlowski, Schad & Scott, 1991).[3]
- Also the current study showed, the prevalence of Ancylostoma ceylanicum infection in human is higher than N. americanus (Inpankaew et al., 2014; Ngui et al., 2012a) particularly in Asia.[4]
Age
- People of all ages are susceptible to Ancylostomiasis.
- Ancylostomiasis commonly affects children and women of childbearing age because of their particular need for micronutrients.[5]
- The overall prevalence of Ancylostomiasis in Zhongzhou was 33.2% with a greater prevalence among males.[6]
Mortality
Gender
- Men are more commonly affected by Ancylostomiasis than women, and this is because most likely related to exposure to contaminated soil.[2]
Region
[[Ancylostomiasis] is a common disease that tends to affect cooler, drier regions, such as Europe, the Middle East, the Mediterranean, North Africa, Pakistan, and northern India as Ancylostoma duodenale is usually found in these regions. Necator americanus predominates in America, Central Africa, eastern and southern India, Indonesia, and the South Pacific. But in many areas of the world mixed infections are found, including parts of Latin America.[2]
