DOH regional director Susana Madarietta said shigella flexneri, amoeba and e-coli are the kinds of bacteria that contaminated the drinking water of residents in Loon brought about by their unsanitary practices.
DOH confirmed the presence of bacteria in 12 out of the 14 rectal swabs from the diarrhea patients in the place.
Test results showed that amoeba, e-coli and shigella flexneri bacteria have caused bacillary dysentery or diarrhea among the patients. Compared to amoeba, shigella flexneri spreads very easily.
The presence of the bacteria means that the water source of Loon has been contaminated.
"The presence of shigella flexneri means water contamination from human feces," Madarietta said.
Loon Mayor Cesar Lopez, a doctor, said the bacteria came mostly from fecal oral root, which means that "it came from water and that it spreads through person-to-person contact."
However, DOH is still awaiting the results of the water analysis from at least three water sources of Loon and two refilling stations. The water analysis is being conducted at the Vicente Sotto Memorial Medical Center.
Even if DOH officials have already pinpointed the bacteria, they will still need the results of the water analysis for comparison.
Madarietta said they have already put in place a command outpost in Loon that will provide medicine, fluids and needles to the residents, adding that they are visiting every household to educate them on proper sanitation and distribute packs chlorine.
Aside from boiling the water, DOH also recommended proper hygiene such as constant hand washing as well as proper waste disposal.
Lopez said the public can already get water from their water source but for safety measures, each household should also practice self-chlorination.
He said one of the major problems in the town is that some houses, especially those in the mountain barangays, do not have toilets.
Because of this, residents are used to disposing of their human wastes outside their homes. The incessant rains last December until the early part of January could have caused the fecal matter to seep into the water sources.
Lopez said with this development, the local government should implement the Sanitation Code of the Philippines, explaining that under the law, each household should have its own sanitary toilet.
He said since Dec. 25, there have been 408 victims of the diarrhea outbreak with two fatalities - a three-year-old girl and a 57-year-old woman. But he added that the 58-year-old woman reported as the latest fatality died of infection in the upper respiratory system.
At least 369 patients were admitted to different hospitals in Bohol. As of yesterday, some 80 patients remain at the Natalio Castillo Memorial Hospital. - Jasmin R. Uy
