Samar logs 225 suspected chikungunya cases, surveillance intensified

TACLOBAN CITY, LEYTE, Philippines — Health authorities in Samar are closely monitoring a surge in suspected chikungunya infections after cases climbed to 225, affecting three municipalities and prompting intensified surveillance and mosquito control measures.

Data from the Provincial Health Office (PHO) showed that Basey recorded the highest number of suspected cases with 124, followed by Gandara with 98, and Paranas with three.

Chikungunya is a viral disease transmitted through the bite of infected Aedes aegypti and Aedes albopictus mosquitoes—the same mosquitoes that spread dengue and Zika. While the disease is rarely fatal, it can cause debilitating joint pain that may persist for weeks or even months.

To confirm the outbreak, the PHO has sent 12 blood samples—six each from Basey and Gandara—to the Research Institute for Tropical Medicine (RITM) for laboratory testing. Results are expected within two to three weeks.

Provincial health records showed that the first suspected cases were reported on Feb. 5, when nine infections were detected in Gandara. No additional cases were recorded in the succeeding months until the disease resurfaced last month, raising concerns about renewed local transmission.

Health officials said the symptoms of chikungunya closely resemble those of dengue and include sudden fever, severe joint pain, muscle pain, headache, skin rashes, and fatigue.

Unlike dengue, however, chikungunya rarely causes severe bleeding or death, but patients often experience prolonged joint pain that can affect daily activities.

In response, the PHO has issued an advisory to all municipalities, particularly Basey, Gandara, and Paranas, urging residents to eliminate stagnant water and other mosquito breeding sites around their homes.

The office also appealed to the public to rely only on information released by the PHO and other health authorities to prevent misinformation and unnecessary panic, and advised residents to avoid self-medication and seek medical consultation if symptoms develop.

Rural health units have likewise been directed to coordinate closely with barangay officials to intensify case monitoring, health education campaigns, and mosquito control measures aimed at preventing further spread of the disease. /cb
