Malaria risk areas in Southern Africa in August!

Malaria remains a serious health concern for travellers to certain parts of Southern Africa, even during the dry season. While August generally sees a decrease in mosquito activity compared to the wetter months, it is important not to become complacent. If you're planning to travel to malaria-prone areas this month, staying informed and prepared is key. Here's what you need to know about malaria risk areas in Southern Africa in August, why June and early winter remain relevant for malaria awareness, and how to prevent infection while travelling.

Malaria Risk Areas in Southern Africa:

Although winter continues across much of Southern Africa in August, malaria transmission can still occur, particularly in low-lying, warmer regions where mosquitoes survive the dry season. Key malaria-endemic areas include:

• Northern and Eastern Namibia, especially the Zambezi Region (formerly Caprivi Strip), Kavango East and West, and parts of Ohangwena and Oshikoto.
• Northern Botswana, including Chobe National Park, the Okavango Delta, and surrounding areas.
• Zimbabwe’s northern regions, including Victoria Falls, Hwange, Mana Pools, and the Zambezi Valley.
• Mozambique, especially along the coastline and in northern provinces such as Cabo Delgado, Nampula, and Zambézia.
• Malawi, particularly the lakeshore regions and Lower Shire Valley.
• Parts of Zambia, including South Luangwa National Park, Lower Zambezi, and Western Province.
• South Africa, specifically the far northeastern regions of Limpopo, Mpumalanga, and northern KwaZulu-Natal, including areas in and around Kruger National Park, Tembe Elephant Park, and Ndumo Game Reserve. 

While transmission risk is generally lower in August due to drier and cooler conditions, localised outbreaks and residual mosquito populations can still pose a threat.

Why August Still Matters for Malaria Awareness:

While August falls within the dry winter season in much of Southern Africa, malaria awareness remains important. Here's why:

• Mosquitoes haven’t disappeared completely—residual populations can survive in warmer, low-lying regions, especially near water sources.
• August is a peak travel month, with many visitors exploring remote wilderness areas where malaria transmission still occurs.
• Occasional winter rainfall or standing water from earlier in the season can continue to support breeding.
• Cross-border movement from high-transmission areas like Mozambique, Angola, or the DRC may contribute to sustained risk in border zones.

In short, even in August, travellers should not let their guard down. Malaria prevention remains essential, particularly for those heading into endemic regions off the beaten track.

Malaria Prevention Tips for Travellers:

Preventing malaria is much easier than treating it. Whether you're visiting the Okavango Delta or exploring the Zambezi River, use these essential malaria prevention tips:

Consult a travel health professional

• Visit a travel clinic at least 4–6 weeks before departure.
• Discuss appropriate antimalarial medication based on your itinerary.
• Some options include atovaquone/proguanil, doxycycline, or mefloquine.

Use mosquito repellent

• Choose one with DEET (?30%), picaridin, or oil of lemon eucalyptus.
• Reapply as instructed, especially after swimming or sweating.

Wear protective clothing

• Opt for long sleeves, long trousers, and light-colored clothing.
• Consider insecticide-treated clothing for extra protection.

Sleep under mosquito nets

• Always use a permethrin-treated mosquito net, especially in rural or remote lodges.
• Ensure the net is properly tucked in and has no holes.

Stay in screened or air-conditioned rooms

• Accommodation with mosquito-proof screens or air conditioning reduces risk significantly.

Be alert to symptoms post-travel

• Malaria symptoms can appear 7–30 days after infection.
• Watch for fever, chills, headaches, and flu-like symptoms.
• Seek immediate medical attention if symptoms arise, even after returning home.

August may be considered a lower-risk malaria month in many parts of Southern Africa, but the risk is not eliminated. By understanding where malaria is still active, recognising the value of early-season awareness, and following preventative measures, you can enjoy your travels safely and confidently.

Stay informed. Stay protected. And enjoy the best of what Southern Africa has to offer this dry season.
