Following the explosive eruption of Kanlaon Volcano in Negros Occidental on Dec. 9, the Department of Health (DOH) has outlined its response plan to address the immediate health risks posed by the disaster.

In a memorandum to DOH Regional Directors Razel Nikka M. Hao (Negros Island), Adriano P. Suba-an (Western Visayas), and Jaime S. Bernadas (Central Visayas), DOH OIC Undersecretary Gloria J. Balboa emphasized the need for preparedness and effective coordination.

The DOH has identified several potential health risks following the volcanic eruption, including respiratory illnesses caused by volcanic ash, which can irritate the respiratory tract, particularly for individuals with pre-existing conditions such as asthma or chronic obstructive pulmonary disease; eye irritation, as ash particles can lead to redness, itching, and pain; skin irritation, with prolonged exposure to ash potentially resulting in rashes; and water contamination, as ashfall increases the risk of waterborne diseases.

The DOH-Central Office has also directed Centers for Health Development (CHDs) or regional offices to ensure an adequate supply of N95 masks, eye protection, water purification tablets or filters, medicines, hand sanitizers, and antiseptic wipes.

The regional offices are also advised to enhance surveillance, prepare for disruptions, and increase coordination with local government units and other agencies.

A cluster approach will be implemented to deliver emergency services in medical care, water, sanitation and hygiene, nutrition, as well as in mental health and psychosocial support.

Hospitals near Mt. Kanlaon have been instructed to prioritize the admission of pregnant women in their third trimester, particularly those at risk of complications. Surge capacity plans should be activated as needed.

Health Secretary Teodoro J. Herbosa urged residents in the affected areas to heed warnings from authorities.

“Our immediate concerns are ash fall and potential lahar should the pyroclastic density currents encounter water," Herbosa said.

He advised those affected by ashfall to stay indoors, close windows and doors, and wear N95 masks if available. If not, any medical mask or even a folded cloth may offer some protection. Eye protection, such as goggles, should be worn, and water contaminated by ash should be avoided.

Frequent handwashing is recommended, and any fruits and vegetables exposed to ash should be thoroughly washed before consumption.

“Seek medical attention for any breathing or eye problems. The DOH is actively monitoring the situation and receiving instructions from President Marcos Jr.,” he added.
