Malaria Tablets

• Infected Mosquito Bites: The primary transmission route is the bite of an infected female Anopheles mosquito. Unlike daytime-biting mosquitoes that transmit dengue, Anopheles mosquitoes are crepuscular and nocturnal feeders, with peak biting activity occurring from dusk through the night until dawn.

• Rare Transmission Routes: In very rare cases, malaria can be transmitted via blood transfusions, organ transplantation, sharing contaminated needles, or vertically from an infected pregnant mother to her unborn child (congenital malaria).

Symptoms of malaria typically appear between 7 to 30 days following an infective mosquito bite, though certain species can lie dormant in the liver and cause illness months later. Common signs include:

• Sudden high fever, shaking chills, and profuse sweating cycles.

• Severe headache, fatigue, nausea, and vomiting.

• Muscle aches, general body pain, and abdominal discomfort.

• Anaemia and jaundice (yellowing of the skin and whites of the eyes) in more pronounced or severe cases.

Note: Malaria is a medical emergency. If left untreated, certain strains (such as Plasmodium falciparum) can rapidly progress to severe complications, organ failure, and fatal outcomes within hours.

Because malaria can escalate rapidly and there is no 100% effective vaccine for all travellers, protection relies heavily on the ABCDE approach (Awareness, Bite prevention, Chemoprophylaxis/Tablets, Diagnosis, and Early treatment):

1. Malaria Tablets (Chemoprophylaxis): Taking prescription anti-malarial tablets (such as Atovaquone/Proguanil, Doxycycline, or Mefloquine) tailored to your destination significantly suppresses the parasite and prevents infection if you are bitten.

2. Rigorous Nighttime Bite Avoidance: Because the vector mosquitoes feed after dark, physical barriers are vital:

   • Apply high-strength DEET-based insect repellent to all exposed skin from dusk onwards.

   • Wear long-sleeved clothing, long trousers, and socks after sunset.

   • Sleep under an insecticide-treated bed net (ITN) if your accommodation lacks air conditioning or secure window screens.

Malaria is endemic in tropical and subtropical regions across the globe. High-risk zones include:

• Sub-Saharan Africa: Bears the vast majority of the global malaria burden, with high transmission rates across West, Central, East, and Southern Africa.

• South and Southeast Asia: Rural and forested regions across parts of India, Indonesia, Myanmar, Cambodia, Vietnam, and Laos.

• Central and South America: Select tropical rainforest and rural agricultural regions in countries like the Amazon basin (Brazil, Peru, Venezuela, and Colombia).
