Soil-Transmitted Helminths in Malaysia landscape: an aborigines study

Area of Science:

• Parasitology
• Public Health
• Tropical Medicine

Background:

• Soil-transmitted helminths (STHs) are parasitic nematodes causing gastrointestinal issues, prevalent in neglected populations globally.
• WHO recommended mass drug administration for STH in 2005, followed by a health education package (HELP) in Malaysia in 2012.

Purpose of the Study:

• To determine the current prevalence of STH infections among the Aboriginal population in Malaysia.
• To identify socio-demographic factors associated with STH infections in this community.

Main Methods:

• Collection of 235 human fecal samples from Aborigine communities in Kedah and Selangor, Malaysia.
• Screening of samples using direct-fecal smear and formalin-ether sedimentation.
• Socio-demographic data gathered via a pre-tested questionnaire.

Main Results:

• High STH infection prevalence of 81.7% detected.
• Trichuris trichiura (76.6%) was the most common STH, followed by hookworms (26.4%) and Ascaris lumbricoides (19.1%).
• Factors associated with STH included age, male gender, indoor toilet access, family size, and living habits; walking barefoot was linked to hookworm.

Conclusions:

• The high prevalence of STH infections in this population is concerning.
• Urgent implementation of health education focusing on behavioral practices and hygiene is crucial.
• Interventions are needed to reduce the disease burden in these rural communities.
