Risk map development for soil-transmitted helminth infections in Argentina

Area of Science:

• Epidemiology
• Parasitology
• Public Health

Background:

• Soil-transmitted helminths (STHs) are Neglected Tropical Diseases requiring soil passage for infectivity.
• STH infections are linked to socioeconomic, environmental, and soil factors.
• Previous studies in Argentina identified STHs in 11 of 23 provinces.

Purpose of the Study:

• To create a specific risk map for STHs in Argentina.
• To identify and rank key characteristics associated with STH presence.
• To guide future STH surveillance and control efforts.

Main Methods:

• Utilized an expert survey and the Analytical Hierarchy Process (AHP) to rank STH risk factors.
• Developed a risk map based on identified characteristics.
• Validated the risk map using existing STH prevalence data.

Main Results:

• A risk map was generated, identifying key STH risk factors.
• Half of Argentina, encompassing central and northern provinces, exhibits suitable conditions for STH development.
• The map effectively correlates with previous prevalence data.

Conclusions:

• The developed STH risk map is a valuable tool for public health initiatives.
• The map aids in identifying areas for baseline data collection and intervention planning.
• It supports targeted surveillance and control of STHs in Argentina.
