Lilongwe, Malawi: Malawi has taken the lead in utilizing the Global Task Force for Cholera Control tool to pinpoint priority areas for multi-sectoral interventions, known as PAMIs or hotspots, marking a significant step towards comprehensive cholera control.

Spearheaded by Dr. Fred Kapaya, a cholera expert from the World Health Organization(WHO) African Regional Office, this data-driven approach incorporated extensive geographical data and vulnerability indicators. By focusing on incidence, mortality, persistence, and cholera test positivity, a numeric threshold categorized priority areas, resulting in the identification of hotspot regions.
 
Moreover, Mangochi, Nsanje, Chikwawa, and parts of Lake Chirwa in Zomba were among the districts recognized with recurrent cholera cases, typically linked to the rainy season and inadequate waste management and sanitation practices. Multi-sectoral interventions have proven effective in reducing cases. Nsanje, for instance, saw a decline in sporadic cases through these measures, with the district’s proximity to Mozambique contributing to cross-border cases.
 
Chikwawa, bordering Mozambique as well, drew attention to the significance of continuous cholera supply distribution and the upgrading of treatment centers. Multi-sectoral approaches combining infrastructure, behavior change campaigns, and cholera supplies played a pivotal role in controlling the disease in this district.

Strategy to Control Cholera

Furthermore, WHO Malawi’s Country Preparedness and IHR Officer, Dr. Gertrude Chapotera explains that the mapping process is a crucial step in generating data and developing a multi-year cholera control plan. Also, PAMI utilizes geographical maps derived from the national census survey by the National Statistical Office to categorize data at the Traditional Authority level. This approach allows for the identification of areas most affected by cholera, enabling precise prioritization of interventions by different partners and stakeholders.

Malawi’s multifaceted approach sets an example for other nations grappling with cholera. It accentuate the necessity of multi-sectoral involvement and tailored strategies to address the diverse challenges of water, hygiene, sanitation, climate change, disaster management, infrastructure, cross-border relations, logistics, and financing.
