December marks the heart of the rainy season across much of Southern Africa - and with it comes an increase in malaria transmission. Warm temperatures, higher humidity, and regular rainfall create ideal breeding conditions for mosquitoes. For travellers planning festive-season safaris or beach holidays, understanding malaria risks and how to stay protected is essential.
Malaria risk areas in Southern Africa
Malaria transmission in Southern Africa remains concentrated in low-lying, humid regions where the Anopheles mosquito thrives.
Countries where malaria is present include Angola, Zambia, Zimbabwe, Malawi, Mozambique, northern Namibia, northern Botswana, and eSwatini, as well as the northeastern parts of South Africa. In South Africa, malaria occurs mainly in Limpopo, Mpumalanga, and the far north of KwaZulu-Natal, including the world-famous Kruger National Park and surrounding reserves.
Mozambique and Zimbabwe experience widespread malaria, particularly along river valleys and coastal plains. Travellers heading to Victoria Falls, the Zambezi floodplains, or Okavango Delta should take extra care, as these areas are among the region’s highest-risk zones during December.
By contrast, destinations at higher altitudes - such as Johannesburg, Windhoek, Gaborone, and Lusaka - are malaria-free year-round.
Why December matters for malaria awareness
December is one of the peak malaria months in Southern Africa. Heavy rains, lush vegetation, and warm nights provide perfect conditions for mosquito breeding. As a result, mosquito numbers surge, and malaria transmission reaches some of its highest levels of the year.
Many travellers underestimate the risk during the festive season. Family trips to game reserves, coastal getaways, and cross-border road journeys often coincide with increased exposure to mosquito bites — especially around dusk and dawn.
Health authorities across the region, including the World Health Organization (WHO) and South Africa’s National Institute for Communicable Diseases (NICD), continue to warn that December to April represents the peak malaria season in Southern Africa. Raising awareness this month is critical, as early preventive action can dramatically reduce infections.
Malaria prevention tips for travellers
With proper precautions, malaria can be prevented. Whether you’re heading out on safari, exploring wetlands, or visiting family in rural areas, these steps will help keep you safe:
- Consult a travel health professional:
- Before travelling, seek advice on antimalarial medication suitable for your itinerary. Preventive treatment is strongly recommended for travel to high-risk areas such as Kruger National Park, northern Namibia, Mozambique, and Zambia.
- Avoid mosquito bites:
- Apply insect repellent containing DEET, picaridin, or IR3535 to all exposed skin.
- Wear long sleeves, trousers, and light-coloured clothing, especially in the evenings.
- Sleep under insecticide-treated mosquito nets or in rooms with screened windows and air conditioning.
- Use a fan or coil to reduce mosquito activity indoors.
- Monitor for symptoms:
- If you experience fever, chills, headaches, or fatigue during or after your trip, seek medical attention immediately. Malaria symptoms can develop up to several weeks after returning home.
- Plan smart for families:
- Families with young children, pregnant travellers, or elderly relatives should take extra care, as these groups are more vulnerable to severe malaria. Always ensure your travel insurance covers medical treatment and evacuation from remote areas.
Final thoughts
December is a beautiful month to explore Southern Africa - from lush national parks to vibrant coastlines - but it is also one of the highest-risk months for malaria. With rising mosquito activity and holiday travel at its peak, preparation is vital.
By identifying malaria zones, staying informed, and taking consistent preventive measures, travellers can enjoy a safe and healthy holiday season across Southern Africa’s stunning landscapes.
