Night Watch Against Malaria:

Heroes of Chilowa Village

In the heart of Chilowa village, located in the Katete District of Eastern Province, Zambians are waging a quiet but determined battle against malaria. Every day, community members are rising to the challenge, using the knowledge, tools, and technology from the U.S. President’s Malaria Initiative (PMI) to build more resilient communities and help eliminate this deadly disease. These health heroes, trained and supported by PMI, are making a significant impact in their community.

Eless Banda and Sara Banda are Community Mosquito Collectors. Their mission? To collect mosquitoes from households in their community. The mosquitoes collected provide important information to the PMI Evolve Project and the Zambia National Malaria Elimination Programme about the effectiveness of malaria interventions such as indoor spraying and insecticide treated bed-nets.

Eless and Sara use a specialized technique to collect these mosquitos. First they spread white linen on the ground and spray anti-insect spray, causing the mosquitoes to fall from the household’s wall onto the fabric. Next, they carefully pick up the mosquitos and store them in petri dishes before sending them to the PMI-supported molecular laboratory based at the National Malaria Elimination Centre in Lusaka.

The collected mosquitoes make it possible for the Zambia National Malaria Elimination Programme and PMI to analyze the mosquitoes for malaria parasites, assess the mosquito’s age, and study the mosquitos behavior to improve the interventions used to prevent malaria.

Meanwhile, Micheal Banda, from Chilowa, is taking on a different but equally crucial role as a human landing collector. Micheal sits outside (after taking malaria prevention medicine in case he is accidentally bitten by an infected mosquito while working), exposing his skin to mosquitoes and catching them with a mouth aspirator as they attempt to bite. The PMI Evolve project sends these mosquitoes to the PMI-supported lab at the National Malaria Elimination Centre for analysis. The mosquitos that Michael collects provide valuable information about malaria transmission rates and mosquito behavior.

Eless, Sara, and Micheal, along with other community collectors, were given special training by the PMI Evolve project and provided tools like digital hygrometers to record temperature, humidity, and other data during their mosquito collection activities.

Their work not only helps to reduce the burden of malaria in Chilowa village but also contributes to a broader understanding of how best to combat this disease across Zambia. Their work is a testament to the power of community involvement in health initiatives, demonstrating that with the right knowledge, tools, and determination, even the most daunting challenges can be overcome.

As we commemorate World Mosquito Day, we recognize and celebrate the efforts of Eless Banda, Sara Banda, Micheal Banda, and all the health heroes who are making a real difference in their communities and in the fight against malaria.
