Handa Ka Na Ba? Disaster Medicine Tips Every Filipino Needs

The second day at an evacuation shelter is almost always harder than the first. On day one, people are still in shock — quiet, cooperative, moving on adrenaline. By day two, the reality sets in: supplies are running thin, no one has restocked, and the family in the corner with a feverish toddler is asking if anyone has paracetamol. At center after center, across different types of disasters, the pattern repeats: the medical supplies that were supposedly “prepared” either weren’t packed, got soaked in the evacuation, or ran out within 36 hours. The families who were okay on day two weren’t the ones who had the most stuff. They were the ones who had thought through medical continuity — not just food and water.

This is especially real during typhoon season in the Philippines, when a single storm can cut off a barangay for days. Floodwater doesn’t just damage homes — it creates the exact conditions for leptospirosis, dengue flare-ups, wound infections, and diarrheal disease to spread fast. If someone in your household depends on daily medication, or has children under five, or has a senior member with a chronic condition, medical preparedness isn’t a bonus item on your checklist. It is the checklist.

Build Your Medicine Backup Before the Storm Signal Goes Up

The most concrete thing you can do right now is check your household’s medication supply and build a minimum two-week backup. Two weeks sounds like a lot, but it accounts for the realistic scenario: a major typhoon hits, flooding persists for several days, and your usual pharmacy or RHU (Rural Health Unit) is closed or inaccessible for at least a week after. One week of backup leaves almost no margin.

For maintenance medications — antihypertensives, metformin for diabetes, asthma inhalers, anti-seizure drugs — this backup is non-negotiable. These are not medications you can skip for three days and “catch up” on later. If you or a family member takes these daily, talk to your doctor now, before typhoon season peaks, about getting a slightly larger prescription fill so you can build that reserve. Many PhilHealth-accredited clinics and RHUs will understand this request during the June–November typhoon window.

Separate your backup supply from your regular daily use supply. Keep it in a waterproof container — a resealable dry bag or a hard-sided waterproof case works well — stored at a height above your expected flood line at home. Label the container with the medication names, doses, and the name of the person they’re for. If you evacuate in a hurry, you grab that container and you know exactly what’s inside.

• Maintenance meds: Minimum 2-week backup per person who takes them daily
• Paracetamol (adults and children’s formulation): At least one full box of each
• Oral Rehydration Salts (ORS): At least 10 sachets — this is your first line against dehydration from diarrhea, especially for children
• Antihistamine (e.g., cetirizine or loratadine): For allergic reactions and rashes that appear during prolonged evacuation
• Antiseptic solution and gauze: For wound cleaning — flood water is heavily contaminated
• Thermometer: One working digital thermometer per household

A small waterproof pouch that keeps medications organized and labeled is the kind of item worth having on hand — not for the dramatic worst-case scenario, but for the more likely one where you’re in an evacuation center and someone needs their blood pressure medication at 7 AM and you can’t find it in the dark.

The Rainy Season Diseases That Catch Families Off Guard

The diseases that spread after a typhoon or flood in the Philippines are predictable — which means they are also preventable, if you know what to watch for and when. The two that catch families most off guard are leptospirosis and dengue, and they behave very differently.

Leptospirosis enters through skin breaks or mucous membranes after contact with floodwater contaminated by animal urine — most commonly rat urine in urban flooding. The incubation period is typically 2 to 30 days after exposure, which means symptoms often show up after the flood has receded and families think the danger has passed. Early symptoms look like ordinary flu: fever, headache, muscle pain. The critical window is early treatment — if leptospirosis is caught in its early phase, it responds well to antibiotics. If it progresses untreated, it can become severe. The rule of thumb: if anyone in your household waded through floodwater and develops fever within the following two to three weeks, bring them to an RHU or hospital and specifically mention the flood exposure. Do not wait for the fever to “pass on its own.”

Dengue follows a different cycle. Typhoons and heavy rains create stagnant water in every container, broken gutter, and tire left outdoors — ideal breeding conditions for Aedes aegypti mosquitoes. Dengue cases typically spike two to three weeks after a major rain event, once the mosquito population has had time to breed. The warning signs that require immediate medical attention — not just home rest — are: bleeding from the nose or gums, rash that appears after the initial fever drops, severe abdominal pain, or persistent vomiting. The DOH and your local RHU maintain dengue surveillance data during outbreak seasons, so if your barangay is flagged as having elevated case counts, treat any fever in a child with extra urgency. For real-time health advisories, the Philippine Red Cross (redcross.org.ph) regularly posts outbreak alerts alongside their disaster response updates.

The Misconception That Makes Evacuation Center Illness Worse

Most families think the main health risk at an evacuation center is contaminated food or insufficient water. Those are real problems — but the pattern that appears repeatedly at shelters is different: the biggest driver of illness spread is the assumption that someone else is managing it. No one in the center has the full picture. Barangay health workers may not have arrived yet. The DOH rapid response team may be two barangays away. In that gap, a child with a respiratory infection shares a sleeping mat with four other children, and three days later a third of the center has coughs.

The practical response to this is not to wait for official medical teams to arrive — it is to be the person in your family group who manages containment at the household level. If someone in your group develops diarrhea, isolate their waste immediately and enforce handwashing with whatever soap is available. If someone has a fever, keep them away from infants. If you notice signs of dehydration in a child — dry lips, no tears, no urination for more than six hours — begin ORS immediately and escalate to whoever has medical training in the center. You do not need to wait for a doctor to start ORS.

Medical Needs for Children, Seniors, and Members With Chronic Conditions

The families that struggled most in shelter situations were almost always those with a member whose medical needs didn’t fit the standard “general population” assumption. Infants need formula or the mother needs conditions where breastfeeding is possible. Toddlers with asthma need their inhaler, not just paracetamol. Lolas and lolos on three different maintenance medications need those three medications in the right doses at the right times — not just one of them.

If you have children in the household, their medical preparedness deserves its own sub-list. For a structured approach to preparing children specifically for typhoon season, including how to talk to them about evacuation without causing fear, the guide on typhoon and earthquake preparedness for kids has age-specific guidance that pairs well with the medical layer covered here.

For elderly members and those with chronic conditions, prepare a one-page medical summary card to keep in the waterproof medicine container. It should list: the person’s name, conditions, current medications with doses and timing, known allergies, blood type if known, and the name and contact of their regular doctor. If they end up being treated by an unfamiliar medical volunteer at an evacuation center, this card means the responder can work safely without having to guess.

For members with disabilities — mobility limitations, hearing impairment, visual impairment — the evacuation plan itself is the medical preparedness. An evacuation that goes wrong because a family member couldn’t move fast enough through floodwater is a medical emergency that preparation could have prevented. Identify beforehand who in your household or immediate neighborhood can assist, and where the nearest accessible evacuation route is. Your barangay disaster risk reduction office should have this information; if they don’t, that’s worth raising. See also: how to work with your barangay on disaster preparedness.

PhilHealth and DOH Access When Normal Systems Are Down

One of the least-discussed gaps in disaster medical preparedness is knowing how to access healthcare when your usual channels are unavailable. Your regular clinic may be closed. Your family doctor may have evacuated. Your PhilHealth card may be waterlogged and unreadable.

PhilHealth coverage does not require a physical card during declared disaster situations. During a state of calamity, PhilHealth typically activates its disaster response protocols, allowing beneficiaries to access services at accredited facilities using alternate verification. The key is to know your PhilHealth number — write it on the medical summary card mentioned above, or save it as a note on your phone with a backup somewhere offline. If you’re unsure of your number, log in to the PhilHealth member portal before typhoon season and note it down.

The DOH deploys Doctors to the Barrios and emergency medical teams during major disasters, and Botika ng Bayan outlets sometimes serve as distribution points for essential medicines in affected areas. At the barangay level, the BHS (Barangay Health Station) is often the first functioning medical contact point after a typhoon — before hospital access is restored. Know where your BHS is and who runs it. That relationship, built before the emergency, is worth more than any app during a crisis.

For the latest disaster-related health advisories and alerts from official agencies, monitor both the NDRRMC and your local DOH regional office. Staying ahead of the storm — including knowing when a Signal No. 3 is imminent — is itself a health intervention. The earlier you act, the more options you have.

What NOT to Do — Mistakes That Turn a Manageable Situation Into a Crisis

Wading through floodwater without foot protection is the most direct path to leptospirosis infection — yet almost every flood event sees people doing exactly this, often because they assume the water is “clean enough” or because they feel the situation demands it. If wading is unavoidable, cover all cuts and wounds first, wear rubber boots if available, and wash off with clean water and soap as soon as possible after exposure. Do not wait until you get home.

Do not self-medicate with antibiotics without guidance. At evacuation centers, the pattern of people sharing medications — particularly antibiotics from someone’s leftover prescription — is common and genuinely dangerous. Antibiotics taken at the wrong dose, for the wrong duration, or for a viral illness (where they do nothing) contribute to resistance and can mask symptoms in ways that delay correct treatment.

Do not assume that because a family member’s fever broke, they have recovered from a dengue-suspect illness. The period after the fever drops in dengue — called the critical phase — is when the most serious complications occur. Continued monitoring for the warning signs listed earlier is essential for 24 to 48 hours after the fever resolves.

And do not wait until the storm signal is raised to gather your medical supplies. By the time Signal No. 2 is up, pharmacies near you are already running low on paracetamol and ORS. The families who had what they needed were the ones who prepared on a calm Tuesday in May, not at midnight before landfall.

The One Thing You Can Do in the Next Ten Minutes

Open your medicine cabinet right now and count how many days of maintenance medication each person in your household has. Write the number down. If anyone has less than 14 days of supply, that is your single most urgent medical preparedness gap — and the one action with the highest return. Schedule the prescription refill or RHU visit this week, not next month.

If no one in your household takes maintenance medication, your ten-minute action is this: check that you have at least one box of paracetamol, one pack of ORS sachets, and an antiseptic solution — and that all of them are stored somewhere accessible, not at floor level. That combination alone handles the majority of the minor-to-moderate medical situations families face in the first 72 hours of a disaster.

Medical preparedness doesn’t require a fully stocked field kit or medical training. It requires knowing your household’s specific vulnerabilities — who needs what, when, and how to get it when normal channels are closed. That knowledge, built now, is what makes the difference on day two.
