BACOLOD City – The Provincial Health Office (PHO) of Negros Occidental has warned residents of increased risks of water- and vector-borne diseases, especially during floods.
In a public health advisory posted in Facebook, the PHO cited information from the World Health Organization (WHO), explaining that floods can lead to a spike in communicable diseases that are either waterborne or vector-borne.
According to the WHO, waterborne diseases such as typhoid fever, cholera, and leptospirosis are often caused by water contamination, which becomes more prevalent during flooding. Meanwhile, vector-borne diseases like malaria, dengue, and yellow fever tend to increase due to stagnant water that serves as breeding sites for mosquitoes.
The PHO warned that symptoms of food and waterborne illnesses may vary, but commonly include diarrhea, vomiting, stomach cramps, fever, nausea, dehydration, headaches, and weakness.
To prevent infection, the PHO advises the public to:
* Wash hands frequently, especially before eating, after using the toilet, and after handling raw food.
* Cook food thoroughly, using a thermometer to ensure it reaches safe internal temperatures.
* Store food properly, refrigerating perishables promptly and avoiding room temperature exposure.
* Avoid cross-contamination, by keeping raw and cooked foods separate, and using different utensils and cutting boards.
* Choose safe water sources, such as bottled or purified water, especially in areas with questionable water quality.
* Handle food safely, including washing fruits and vegetables well, and avoiding raw or undercooked seafood, meat, and poultry.
The PHO also reminded the public to seek medical attention if symptoms occur.
“Antibiotics should only be taken if prescribed by a physician,” the advisory further stated.
In a related development, the Bacolod City Health Office reported 15 leptospirosis cases, including six deaths, from January 2 to July 12, 2025. This reflects a 50% increase compared to the same period last year, which recorded 10 cases and four deaths.
The city has also logged a total of 559 dengue cases with two deaths this year. Health officials noted that the number of dengue cases continues to rise weekly.
The public is urged to stay vigilant, avoid wading in floodwaters, and eliminate mosquito breeding sites to help curb the spread of these illnesses./PN
