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]
