Carry malaria medication when traveling to high-risk areas, particularly regions prone to increased rainfall and standing water. Adhere to prescribed malaria prophylaxis (preventive medication), especially for vulnerable groups and individuals residing in or visiting high-risk zones.
Seek prompt medical attention at recognized health facilities when symptoms of malaria such as fever, chills, headache, or body weakness are observed.
Store all medications properly in a safe, cool, and dry place to prevent spoilage, contamination, or loss of effectiveness.
Promote the use of insecticide-treated mosquito nets (ITNs), especially during nighttime, to reduce exposure to mosquito bites. Maintain clean surroundings by eliminating stagnant water and improving sanitation to limit mosquito breeding sites.
Strengthen community awareness and surveillance by encouraging early reporting of suspected malaria cases and supporting public health interventions.
