The Department of Health (DOH) on Tuesday assured those affected by the Kanlaon Volcano eruption that there are enough supplies of N95 masks.

It also ordered its central office (CO) to remind Centers for Health Development (CHDs) or regional offices to ensure an adequate supply of eye protection or goggles, water purification tablets or filters, medicines, hand sanitizers, and antiseptic wipes.

The CO also reminded CHDs “to enhance surveillance, prepare for potential disruptions, increase coordination with local government units and other agencies.”

The DOH said CHDs will also be implementing a cluster approach to delivering emergency services for medical and public health; water, sanitation, and hygiene; nutrition; and mental health and psychosocial support.

Meanwhile, the Health department reminded hospitals and health facilities near Mt. Kanlaon to prioritize the admission of pregnant women in their third trimester, particularly those at risk of complications.

Hospitals were also reminded to activate their surge capacity plans as needed.

"To those near Kanlaon volcano, and along the forecast path of winds: listen to advice from Philippine Atmospheric, Geophysical and Astronomical Services Administration and your local governments,” DOH Secretary Ted Herbosa said.

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

Residents in areas affected by ash fall are advised to “stay indoors, close all doors and windows.”

"Use N95 masks if available; any medical mask or even folded clothes may help if N95 masks are not on hand. Use eye protection like goggles. Do not use water that may have been contaminated by ash,” Herbosa said.

"Wash hands frequently with soap and water. When preparing food, wash and clean fruits and vegetables that may have been exposed to ash,” he added.

Kanlaon Volcano erupted on Monday afternoon, prompting the Philippine Institute of Volcanology and Seismology (Phivolcs) to place it under Alert Level 3 or "high level of volcanic unrest."

State volcanologists also warned of potential similar or stronger eruptions in the coming days.

Phivolcs also cautioned about lahar or muddy streamflows, which may occur due to heavy rains and thunderstorms.

Potential health risks following the volcanic eruption include respiratory illnesses (volcanic ash can irritate the respiratory tract, especially for individuals with pre-existing conditions like asthma, chronic obstructive pulmonary disease, or the like); eye irritation (ash particles can cause redness, itching, and pain in the eyes); skin irritation (prolonged ash exposure may lead to skin rashes); and water contamination (ashfall increases the risk of waterborne diseases).

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

No immediate reports of casualties or damage as of writing.
