Malaria in Southern Africa in January: What travellers should know!

January sits right at the heart of the malaria season in Southern Africa. Warm temperatures, frequent rains, and high humidity combine to provide perfect breeding conditions for the mosquitoes that transmit malaria. For travellers heading to the region - whether for safari, beach vacations, or exploring rural landscapes - staying informed and taking preventive measures is essential.

Malaria risk areas in Southern Africa
In January, malaria risk remains high in many of the region’s low-lying, warm and humid zones where the malaria-carrying Anopheles mosquitoes thrive.

Key high-risk areas include:

• Kruger National Park and surrounding lowveld regions in South Africa - including the provinces of Limpopo and Mpumalanga, plus the far northern part of KwaZulu-Natal.
• Border regions and cross-border corridors connecting South Africa to neighbouring countries such as Mozambique, Zimbabwe, Zambia, Malawi, or Namibia.
• Other malaria-endemic zones in Southern Africa — including parts of northern Namibia (e.g. Zambezi / Caprivi region), northern Botswana, and rural wetlands, floodplains, river valleys or low-altitude zones across the region.

By contrast, many high-altitude or drier inland areas - such as large parts of central South Africa, and major cities like Johannesburg or Windhoek - remain low-risk or malaria-free, even during the season.

Why January matters for malaria awareness

• January typically marks the peak of malaria transmission in many parts of Southern Africa. The combination of warm summer temperatures, high humidity and persistent rainfall creates ideal conditions for mosquito breeding and survival.
• For travellers - especially those on safari, visiting river valleys, wetlands, or exploring rural zones - January is one of the riskiest months. Many journeys also coincide with the holiday season or school holidays, increasing the likelihood of travel to high-risk zones.
• Because mosquitoes bite mostly from dusk to dawn, travellers may underestimate the risk -particularly if they spend daytime hours outdoors. Yet nighttime bites are common, so protective measures remain essential throughout the evening and overnight hours.
• Returning travellers who develop a fever - even several weeks after leaving a malaria area - should remain alert. Malaria may not always strike immediately, and delayed diagnosis can be dangerous. Medical attention should be sought promptly if symptoms such as fever, chills or flu-like illness appear.

Malaria prevention tips for travellers
If you're planning a trip to Southern Africa in January - be it for safari, nature, or visiting relatives - the right precautions can greatly reduce your risk. Here’s what to do:

• Consult a travel-health professional before your trip. For stays in high-risk zones (e.g. Limpopo, Mpumalanga, Kruger National Park, border areas, wetlands), prophylactic antimalarial medication may be recommended.
• Avoid mosquito bites, especially between dusk and dawn. Wear long sleeves and long pants, preferably light-coloured, covering ankles and wrists.
• Use a mosquito repellent on exposed skin with proven active ingredients such as DEET.
• Sleep under insecticide-treated bed nets or use screens on windows and doors. Staying in lodgings with fans or air-conditioning further reduces mosquito activity.
• Avoid outdoor exposure at night, especially near wetlands, riverbanks, or floodplains. If you're walking or travelling after dusk, ensure you’re fully covered and use repellent.
• Know the symptoms and act fast: Fever, chills, headache and malaise - even weeks after leaving a malaria-endemic area - can be signs of malaria. Seek medical attention without delay.

Final thoughts

January in Southern Africa is a beautiful time to travel - lush landscapes, vibrant wildlife and warm weather. But it’s also when the risk of malaria is at its highest across many parts of the region. Whether you’re heading out on a safari, visiting remote communities or exploring rivers and wetlands, taking malaria seriously and preparing properly can help ensure a healthy, enjoyable trip.

Plan ahead, stay informed and protect yourself - so you can enjoy everything Southern Africa has to offer without compromising your health.
