The Department of Health (DoH) has said there was no outbreak of cholera in Iligan City despite earlier reports of nine cases among evacuees. Between May 26 and June 28, nine confirmed cases of cholera were reported involving children aged nine months to six years, and a 62-year-old female. The victims manifested symptoms such as diarrhea, vomitin, and/or abdominal pain before testing positive for Vibrio cholerae Ogawa, the cholera-causing bacteria. Of the nine, four of them were reported from evacuation centers while the rest were home-based, residing in various villages. After review of the data, however, neither Region 10 nor Iligan has declared a cholera outbreak. Despite this, Health Secretary Paulyn Ubial called on local health authorities to be vigilant against the emergence of disease outbreaks, and ordered health responders for a house-to-house visit to home-based refugees and provide them health services. As of June 26, at least 27 Marawi City refugees staying in evacuation camps had died of various diseases with the most common being acute gastroenteritis, upper respiratory tract infection, diarrhea and skin problems.
