The community in Kalaki is expressing gratitude for the ongoing Indoor Residual Spray (IRS) program, which aims to combat malaria in the district.
IRS is a vital public health measure involving the application of insecticide to interior surfaces such as walls, ceilings, and grass-thatched roofing to eliminate mosquito populations that transmit malaria and other diseases.
In Kalaki’s four sub-counties, the Ministry of Health is utilizing Prallethrin, a highly effective insecticide known for controlling mosquito infestations.

The program, launched on December 13, 2024, in Ochelakur Sub-county, has already made a significant impact in previous exercises by reducing malaria cases and improving the health of local communities.
Judith Amuge, a resident of Olepu West in Ochelakur, expressed her excitement upon seeing the IRS team visit her home. “I’m so happy to see the team here. It feels good to know that we are being supported in the fight against malaria,” she said.
In Olilimo village, Grace Achen, who lives near the lake, emphasized the program’s importance in preventing malaria. Having previously tested positive for malaria along with her baby, she is optimistic about the initiative. “This spray will definitely help in fighting malaria,” she remarked.

Many other residents echoed similar sentiments, noting fewer visits to health facilities and a significant drop in malaria cases in their households.
Esther Akota, from Achilo village, explained that before the IRS program, she visited the health facility every two weeks for malaria treatment. “Since the program began, these visits have significantly reduced, and fewer people are testing positive for malaria,” she shared.
The program’s impact extends beyond reducing malaria cases, strengthening community efforts to combat the disease.
Daniel Eriku, the Vice Chairperson of Opundi village, welcomed the launch of the program at his home and encouraged residents to cooperate with Village Health Teams (VHTs). “We must all help by removing our belongings from inside the house so that the spraying can be done smoothly,” he urged.
Malaria focal point person and vector control officer, Jimmy Ariong, who coordinates the IRS program, called on the community to embrace the initiative fully. He highlighted the ongoing threat malaria poses, particularly to children under five, and noted that mosquito nets are also provided to pregnant women to enhance protection.
Dr. Anthony Eriatu, the District Health Officer for Kalaki, explained that the IRS treatment remains effective for 6 to 9 months, killing mosquitoes that come into contact with treated surfaces. He advised homeowners to clean their walls before spraying to maximize its efficacy.

The program targets four sub-counties—Bulululu, Ochelakur, Anyara, and Ogwolo—which consistently report high malaria burdens in the district.
“In areas like Ochelakur, where malaria prevalence remains high, it’s crucial to continue these efforts,” Dr. Eriatu emphasized.
For maximum effectiveness, IRS is conducted just before the peak malaria transmission seasons, which in Uganda occur twice a year: between April and June, and September and November. These periods coincide with the rainy season, which creates ideal breeding grounds for mosquitoes.
In 2023, Kalaki District recorded a malaria prevalence rate of 76%, meaning 76 out of every 100 people tested were positive.
Despite its success, the IRS program has faced minor challenges, such as residents’ discomfort with moving household items before spraying. However, the overall reception remains positive, with communities recognizing the initiative’s role in reducing malaria cases and enhancing public health.
