Summary
Cambodia
Area of Science:
- Public Health
- Tropical Medicine
- Epidemiology
Background:
- Cambodia has made significant strides in malaria control, aiming for nationwide elimination by 2025.
- The Malaria Elimination Action Framework (MEAF 2016-2020) targets high-risk populations, including mobile and migrant groups.
Purpose of the Study:
- To evaluate the effectiveness of malaria control interventions.
- To assess progress towards malaria elimination goals using MEAF indicators.
Main Methods:
- A cross-sectional household survey (Cambodia Malaria Survey 2020) was conducted.
- The survey involved 4,000 households across 100 villages in malaria-endemic areas.
Main Results:
- High ownership (98.4%) but lower usage (79.5%) of long-lasting insecticide-treated nets (LLINs).
- Forest visitors showed high LLIN use (88.9%) during forest stays, with improved protection compared to previous surveys.
- Knowledge of malaria prevention was high, but diagnosis and treatment awareness was inconsistent; private providers were a common source of care.
Conclusions:
- Malaria prevention interventions, particularly LLIN distribution, have benefited high-risk groups like forest visitors.
- Sustained efforts are needed to ensure consistent LLIN and repellent use among forest visitors.
- Strategies must address declining LLIN usage among at-risk populations and maintain public awareness to prevent malaria resurgence and achieve elimination.
