Malaria risk rises across Southern Africa in December as rainy season and holidays begin

December marks the start of the main malaria transmission season across much of Southern Africa, coinciding with the region’s summer holidays and the onset of the rainy season. Warmer weather and increased rainfall create greener landscapes and better wildlife-viewing conditions, but also favour mosquito breeding and malaria transmission. For the African travel trade, this means that malaria remains a key health consideration for clients visiting low-lying areas, national parks and game reserves in December 2026. The risk varies widely between countries and even within countries, so sellers must provide tailored advice for each itinerary.

The groups most affected by malaria risk in December include safari travellers, self-drive holiday makers, business travellers, groups, MICE, students, diaspora and cross-border travellers. Popular destinations such as Kruger National Park, Okavango Delta, Victoria Falls, Hwange, Chobe, South Luangwa, Etosha and Lake Malawi all fall within malaria-risk zones during the rainy season. Urban malaria risk is also present in countries like Mozambique, Malawi and Angola, so even city-based travellers may be exposed. Agencies should remind clients that short stays, luxury accommodation or screened rooms do not eliminate risk, and that the most appropriate preventive measures depend on the full itinerary and individual health circumstances.

For the travel trade, the practical impact is clear: sellers should advise all clients visiting malaria-risk areas to arrange a pre-travel health consultation several weeks before departure. Prescription antimalarial medication is generally recommended for high-risk destinations, with options including atovaquone/proguanil, doxycycline and mefloquine as confirmed by the CDC and WHO. Clients should also use an effective mosquito repellent containing DEET or icaridin (picaridin), wear long-sleeved clothing in the evening, and choose accommodation with air conditioning, screens or insecticide-treated nets. Sellers should brief clients on the symptoms of malaria and the need for urgent medical attention if fever develops during or after travel.

Cross-border itineraries are common during the festive season, with many travellers combining South Africa, Eswatini, Mozambique, Zimbabwe, Botswana, Namibia and Zambia in a single trip. Each country has its own malaria-risk zones and transmission seasons, so risk assessments must cover the entire route. For example, a self-drive holiday from Johannesburg through Kruger, Maputo, Chobe and Victoria Falls will involve multiple malaria-risk areas, each with different levels of risk and preventive recommendations. Agencies should check the latest entry rules, health requirements and recommended medications for each country, and advise clients to carry proof of consultation if required at border crossings.

In comparison with other African markets, Lesotho stands out as malaria-free due to its high altitude and cooler climate, in contrast to its high-risk neighbours. This makes Lesotho a unique option for clients seeking a malaria-free mountain destination. By contrast, East African countries such as Kenya and Tanzania have year-round malaria risk, including in major safari areas and coastal resorts. This highlights the continent-wide challenge of malaria prevention for the African travel trade, and the need for consistent health messaging across all regional destinations.

Background figures from the WHO World Malaria Report 2025 and CDC country pages confirm the official risk classifications for each country. South Africa’s risk is concentrated in the north-east (Kruger, Lowveld, Limpopo, uMkhanyakude District), while Mozambique, Zambia, Malawi and Angola have nationwide risk. Botswana’s risk is seasonal and focused in the north (Okavango, Chobe, Moremi), and Namibia’s risk is highest in the north and north-east (Kavango, Zambezi, Kunene, Omusati, Oshana, Ohangwena, Oshikoto, Omaheke, Otjozondjupa). Zimbabwe’s risk is highest below 1,200 metres, especially in the Zambezi Valley and national parks. The SADC SARCOF-33 climate outlook for 2026/27, released in August 2026, forecasts below-normal rainfall across central and southern SADC due to a strong El Niño, with wetter conditions in the north and north-east. However, established malaria-risk areas remain relevant even in drier years, so sellers should not assume lower rainfall means lower risk.

The history of malaria transmission in Southern Africa explains why December is structurally important. The start of the rainy season brings higher temperatures and increased mosquito breeding, which in turn raises malaria risk in seasonal areas. This period also coincides with the summer holiday season, when regional and international travel peaks. The combination of increased travel and higher transmission risk makes December a critical month for malaria awareness and prevention in the travel trade.

There are several open questions for sellers and travellers. No official malaria burden statistics (case numbers or deaths) were confirmed from background searches, and no safari tourism visitor figures were obtained. Yellow fever entry rules and the timing of required health consultations could not be retrieved from official sources in this session. Agencies should check with national health authorities for the latest entry requirements, vaccination rules and recommended consultation timing. The lack of official data on urban malaria case numbers is a gap, especially for clients visiting cities in Mozambique, Malawi and Angola.

The outlook for the African travel trade is that increased regional travel during the festive season will raise the importance of pre-travel health preparation. Urban malaria risk in Mozambique, Malawi and Angola remains a gap in traveller awareness that the trade can help address. Agencies should continue to provide clear, up-to-date advice on malaria prevention, including the need for antimalarial medication, mosquito-bite prevention and prompt recognition of symptoms. As climate patterns and travel flows change, the trade’s role in supporting safe and healthy travel across Southern Africa will remain essential.
