Malaria: Prevention, Symptoms, and the Necessity of Professional Medical Care

Malaria is a life-threatening parasitic disease transmitted by Anopheles mosquitoes. It requires prompt diagnosis and prescription antimalarial treatment. Self-treatment is dangerous.

Prevention (ABCD)

• Awareness of risk (destination, season).
• Bite avoidance: DEET/picaridin repellent, permethrin-treated nets/clothing, screens, air conditioning.
• Chemoprophylaxis: Atovaquone-proguanil, doxycycline, mefloquine, or tafenoquine per CDC/WHO guidelines for region.
• Diagnosis promptly if fever develops during/after travel to endemic area.

Symptoms

• Cyclic fever, chills, sweats (classic but not universal).
• Headache, myalgia, fatigue, nausea, vomiting.
• Severe malaria: cerebral involvement, severe anemia, AKI, ARDS, hypoglycemia.

Critical Actions

1. Seek medical care immediately for fever within 3 months of travel to malaria zone.
2. Request blood smear or rapid diagnostic test (RDT).
3. Complete full course of prescribed artemisinin-based combination therapy (ACT) or alternative.
