Overview of Malaria in Zambia

Malaria is a prevalent disease in Zambia and poses a significant health risk to travelers. It is a mosquito-borne infectious disease caused by the Plasmodium parasite. The most common species of Plasmodium in Zambia is Plasmodium falciparum, which is known to cause severe malaria.

Transmission of Malaria

Malaria is transmitted through the bites of infected female Anopheles mosquitoes. These mosquitoes are prevalent in Zambia, particularly in rural and peri-urban areas with abundant standing water. The risk of contracting malaria is highest during the rainy season when mosquito populations thrive.

Prevalence of Malaria in Zambia

Malaria is hyperendemic in Zambia, meaning that it is present throughout the year and poses a significant public health burden. According to the World Health Organization (WHO), Zambia accounted for approximately 4% of the global malaria cases in 2019. The disease is a major cause of illness and death, particularly among young children and pregnant women.

High-Risk Areas

While malaria is present throughout Zambia, certain regions have a higher prevalence of the disease. The provinces most affected by malaria include Luapula, Northern, and Muchinga. Additionally, rural areas, particularly those near bodies of water, are at an increased risk of malaria transmission.
