- The research utilized remote sensing and GIS to analyze environmental factors (like elevation and rainfall) and social factors (such as population density and access to healthcare) to create a comprehensive malaria risk map.
- Results showed that 37% of the city is classified as high to very high malaria risk, providing crucial information for targeted health interventions and resource allocation in the area.
Article Abstract
Background: Malaria is a major public health issue in Nekemte City, western Ethiopia, with various environmental and social factors influencing transmission patterns. Effective control and prevention strategies require precise identification of high-risk areas. This study aims to map malaria risk zones in Nekemte City using geospatial technologies, including remote sensing and Geographic Information Systems (GIS), to support targeted interventions and resource allocation.
Methods: The study integrated environmental and social factors to assess malaria risk in the city. Environmental factors, including climatic and geographic characteristics, such as elevation, rainfall patterns, temperature, slope, and proximity to river, were selected based on experts' opinions and literature review. These factors were weighted using the analytic hierarchy process according to their relative influence on malaria hazard susceptibility. Social factors considered within the GIS framework focused on human settlements and access to resources. These included population density, proximity to health facilities, and proximity to roads. The malaria risk analysis incorporated hazard and vulnerability layers, along with Land use/cover (LULC) data. A weighted overlay analysis method combined these layers and generate the final malaria risk map.
Results: The malaria risk map identified that 18.2% (10.5 km) of the study area was at very high risk, 18.8% (10.9 km) at high risk, 30.4% (17.8 km) at moderate risk, 19.8% (11.5 km) at low risk, and 12.6% (7.3 km) at very low risk. A combined 37% (21.4 km) of Nekemte City was classified as at high to very high malaria risk, highlighting key areas for intervention.
Conclusions: This malaria risk map offers a valuable tool for malaria control and elimination efforts in Nekemte City. By identifying high-risk areas, the map provides actionable insights that can guide local health strategies, optimize resource distribution, and improve the efficiency of interventions. These findings contribute to enhanced public health planning and can support future regional malaria control initiatives.

Background: Female Genital Mutilation/Cutting (FGM/C) poses a significant public health challenge in developing countries, leading to increased risks of adverse obstetric outcomes such as caesarean section, postpartum hemorrhage, episiotomy, difficult labor, obstetric tears/lacerations, instrumental delivery, prolonged labor, and extended maternal hospital stays. The study aimed to determine the prevalence and factors associated with FGM/C among Tanzanian women who had given birth within five years preceding the Survey.
Method: This study utilized an analytical cross-sectional design based on data from the 2015-2016 Tanzania Demographic and Health Survey and Malaria Indicators Survey (TDHS-MIS).

Background: Malaria incidence in the Greater Mekong Subregion has been on the decline, and most remaining malaria risk in the region is concentrated among hard-to-reach populations, especially those with exposure to forested areas. New vector control tools focused on outdoor protection in forest settings are needed for these populations.
Methods: The delivery of a 'forest pack' containing a volatile pyrethroid spatial repellent (VPSR), a topical repellent, and pyrethroid treatment of clothing was evaluated in an operational study in Cambodia.

Malaria poses a serious global health problem, with half the world population being at risk. Regular screening is crucial for breaking the transmission cycle and combatting the disease spreading. However, current diagnostic tools relying on blood samples face challenges in many malaria-epidemic areas.
