The Mati City government has declared a diarrhea outbreak in Sitio Magum, Barangay Macambol, Mati City.
The Mati City Health Office and the Davao Oriental Provincial Health Office have initiated immediate intervention.
The Mati City Epidemiology Surveillance and Response Unit has recorded 45 cases of acute watery diarrhea in the area as of Feb. 25.
Health officials suspect that contaminated water was the primary source of the illness.
Initial investigation indicated that recent modifications to the local water distribution system may have introduced pollutants. Tests conducted on water samples from affected areas revealed the presence of E. coli and coliform bacteria in household faucets and water pipes.
The highest concentration of cases was in Sitio Magum 2 with 29 infections. Other affected locations were Magum 1A and Magum 1B. The attack rate in Magum 2 is 9.24 percent, making it the most vulnerable area.
Common symptoms reported by 98 percent of the patients were loose bowel movement, stool consistency changes (67 percent), abdominal pain (56 percent), fever (23 percent), and vomiting (21 percent).
Most patients were children between one- to five-years-old. Most of the cases were females.
The Mati CHO has implemented the following measures in response to the outbreak – conducting case investigations and environmental assessments; distributing oral rehydration solutions, zinc supplements, and multivitamins; collecting additional water samples for bacteriological analysis; organizing sanitation inspections and community cleanup efforts; and educating residents on proper hygiene and safe water practices.
Thirty-nine individuals have recovered and six remain under observation – two receiving hospital care and four under monitoring at home. No fatalities have been recorded.
Due to leaks and contamination risks, the city government advised against using the current water distribution system and residents were encouraged to source water from alternative supplies or boil their drinking water to prevent infection.
The Mati CHO seeks to enhance water treatment facilities and upgrade sanitation infrastructure. The local government plans to implement stricter regulations to guarantee access to safe drinking water and prevent similar health crises.
Health officials urged residents in affected areas to stay alert, report any symptoms promptly, and maintain proper hygiene practices to curb the spread of the illness.
