The Department of Health (DOH) has noted a rapid growth in the number of typhoid fever cases in Guihulngan City, Negros Oriental.
From June to July 2011 alone, there were already 78 recorded typhoid fever cases in the province.
Barangay Poblacion, with 30, topped the list of having most number of cases reported.
Investigations conducted by the Regional Epidemiology and Surveillance Unit (RESU) revealed that the drinking water of some Guihulngan City residents is contaminated with fecal coliform, a bacteria that can be found in human feces.
RESU has advised the local government to set up an improvised chlorinator for the water reservoir in order to manage the contamination.
According to DOH, should the number of cases continue to increase in the upcoming days, they will be forced to declare a typhoid outbreak in the locale. (source)
