A diarrhea outbreak was declared in a barangay in Mati City, Davao Oriental.

Contaminated water reportedly caused the outbreak.

Data from the City Health Office (CHO) showed at least 45 cases were recorded in Barangay Macambol as of February 25, 2025.

Of the 45 patients, 39 have already recovered, two are still admitted, and four are being monitored at home.

Most of them are children, one to five years old. They experienced loose bowel movement, stomachache, vomiting, and fever.

CHO was alarmed of the number of cases, prompting the office to declare an outbreak in the area.

According to the City Epidemiology Surveillance and Response Unit, the disease was caused by contaminated water.

“Water testing in affected areas detected the presence of E. coli and coliform bacteria in some sources, including water pipes and household faucets,” the city government said in a Facebook post.

Getting water from the water reservoir is currently prohibited due to leaks and contamination risks.

Households have been advised to get water from alternative sources or boil the water before drinking.

In response to the outbreak, CHO conducted active case finding and an environmental survey; provided oral rehydration solutions and multivitamins to those affected; and launched a massive cleanup drive and sanitation inspections.

CHO also planned to improve the water treatment facilities and sanitation infrastructure.
