Malaria in Southern Africa: What travellers need to know in May!

May signals the end of the rainy season across much of Southern Africa, but the risk of malaria remains real for travellers. As the climate shifts and mosquito habitats expand, it’s more important than ever to stay informed and take proactive health measures.
Whether you're planning a safari, beach holiday, or cross-border adventure, here’s everything you need to know about malaria in Southern Africa in May 2025.

Malaria risk areas in Southern Africa:

Even though rainfall begins to taper off in May, lingering humidity and standing water mean mosquito populations—and malaria risk—persist in many regions. The following areas remain particularly vulnerable:

• Mozambique: Central and northern provinces remain malaria hotspots. The humid post-rainy conditions continue to support high transmission rates.
• Zimbabwe: Northern destinations such as Victoria Falls, Hwange, and Mana Pools National Park still report malaria cases. Risk is lower than peak season, but caution is essential.
• Botswana: The Okavango Delta, Chobe, and other northern regions retain moisture, making them susceptible to mosquito-borne diseases.
• Namibia: Malaria remains a concern in the Zambezi Region (Caprivi Strip) and along river systems near the Angolan border.
• South Africa: Areas in Limpopo, Mpumalanga, and the Kruger National Park still experience malaria transmission, though less intensely than during March or April.
• Zambia & Malawi: Malaria cases continue in the Lower Zambezi, South Luangwa, and Lake Malawi areas due to mild temperatures and post-season water accumulation.

Why May still matters for malaria awareness:

May may not be the height of malaria season, but residual risks remain. The drop in rainfall does reduce breeding grounds, but mosquitoes and transmission can persist into the early dry season.
In fact, travellers often become complacent in May, thinking the danger has passed. However, mosquito activity continues, especially in low-lying, humid, and poorly drained areas. Don’t drop your guard just yet!

Malaria prevention tips for travellers:

If you are planning a trip to malaria-endemic areas in May, consider the following precautions:

• Take antimalarial medication: Consult a travel health professional for recommended prophylactics such as Malarone, Doxycycline, or Lariam, depending on your health condition and travel duration.
• Use mosquito repellent: Apply DEET-based repellents to exposed skin and clothing.
• Wear Protective Clothing: Long-sleeved shirts and long pants reduce mosquito bites, especially in the evening.
• Sleep under a mosquito net: When staying in high-risk areas, opt for accommodations with insect-proof measures and use bed nets.
• Choose air-conditioned rooms: Mosquitoes thrive in warm, humid environments; air-conditioned rooms provide extra protection.
• Be vigilant after travel: If you experience fever, chills, or flu-like symptoms after returning from a malaria-endemic area, seek medical attention immediately.

May brings milder malaria risks, but it’s not yet the end of the danger zone. Whether you're exploring game reserves, riverbanks, or tropical beaches, proactive protection is your best travel companion.
