THE Mati City Health Office (CHO) has advised residents of Macambol, Mati City, to stay alert and practice proper hygiene following an outbreak of acute watery diarrhea (AWD) in the area.
On February 24, 2025, the City Epidemiology Surveillance and Response Unit (CESRU) reported 43 AWD cases, which health officials suspect were caused by contaminated water. Sitio Magum 2 recorded the highest number of cases (29), followed by Magum 1A and Magum 1B. With an attack rate of 9.24 percent, Magum 2 remains the highest-risk area.
Symptoms reported by patients included loose bowel movement (98 percent), changes in stool consistency (67 percent), abdominal pain (56 percent), fever (23 percent), and vomiting (21 percent). The most affected group is children aged one to five, with a higher incidence among females.
Water testing confirmed the presence of E. coli and coliform bacteria in some sources, including household faucets and water pipes. According to the CHO’s preliminary investigation, a recent change in the water distribution system may have allowed contaminants to enter the supply.
By February 25, the number of affected individuals had risen to 45, but 39 had already recovered. Six active cases remain—two hospitalized and four under home monitoring. No fatalities have been reported.
The CHO has launched active case finding and environmental surveys, distributed oral rehydration solutions (ORS), zinc, and multivitamins, collected water samples for bacteriological testing, and conducted a large-scale clean-up and sanitary inspection.
Awareness campaigns on hygiene and water treatment are also underway.
Authorities have advised residents to avoid using the contaminated water supply and instead rely on alternative sources or boil water before consumption.“ Health officials are advising residents in affected areas to remain vigilant, report symptoms immediately, and practice proper hygiene to mitigate further spread of the illness,” the CHO said.
To prevent future outbreaks, the CHO and local government plan to strengthen water treatment facilities and improve sanitation infrastructure. RGP
