The Silent Danger in Floodwaters: Rise of Leptospirosis in the Philippines

Wading through floodwaters in the Philippines is no longer just an inconvenience – it has become a harsh reality for countless Filipinos. With persistent rains, poor drainage, and inadequate flood control, water can rise quickly without warning, disrupting classes, work, and daily routines. A short but heavy downpour could turn a simple trip to school or work into a difficult and dangerous journey through murky water.

Floodwaters carry all kinds of danger – sharp debris, exposed manholes, and even live wires – making every step a gamble with your safety. Yet what makes flooding even more alarming are the perils you cannot see. Floodwaters are often contaminated with garbage, sewage, and animal waste, making them breeding grounds for disease, particularly leptospirosis.

What is Leptospirosis?

According to WebMD, leptospirosis is a bacterial infection caused by Leptospira interrogans, which is often found in the urine of infected rodents and farm animals. This bacteria can contaminate soil and water. People who wade in floodwaters are at risk of infection when the bacteria come in contact with the skin, especially when there are cuts, wounds, and dry areas.

Symptoms typically appear 5-14 days after exposure, and may include headache, muscle pain, skin rash, vomiting, diarrhea, and jaundice. If untreated, it can lead to severe complications like kidney damage, meningitis, liver failure, or even death.

Leptospirosis is treated with antibiotics, such as doxycycline. It should be initiated as soon as a healthcare provider identifies the risk of infection.

Rising Cases in Flood-Affected Areas

In recent weeks, recurring floods in Metro Manila and nearby provinces have led to a significant rise in leptospirosis cases. To address this surge, several government hospitals began setting up dedicated “fast lanes” since August, designed to provide quicker risk assessments and more efficient treatment for those exposed to floodwaters or already exhibiting symptoms of the disease.

The DOH warns the public that delaying treatment or seeking medical care only after severe symptoms appear puts one at greater risk of life-threatening complications and even death. According to the Department of Health (DOH), the Philippines has recorded 4,859 leptospirosis cases since June, with 52 deaths linked to the disease.

In situations like this, having an emergency health card in the Philippines can be a game-changer. The ER Guard Plus by Medicare Plus can provide emergency care and in-patient care when it matters most—serving as your reliable health anchor and providing peace of mind amid the silent dangers brought by floods.

A Guide to Staying Safe

What To Do

Avoid wading in floodwaters whenever possible. If unavoidable, the Centers for Disease Control and Prevention (CDC) advises people to wear waterproof protective clothing and shoes to reduce skin contact.
Wash thoroughly with soap and clean water after contact with floodwaters.
Cover wounds or cuts with waterproof bandages before going out during floods.
Keep an eye out for possible symptoms.
Seek medical care if symptoms appear. Early diagnosis and treatment can prevent severe and life-threatening complications.
Take prophylaxis (such as doxycycline) only when prescribed by a healthcare professional, especially if you are in high-risk areas.
Stay hydrated and rest to support recovery if already undergoing treatment.

What Not To Do

Do not ignore early symptoms or assume that they will go away on their own, especially after a known exposure to floodwaters. Delaying treatment of leptospirosis can lead to severe complications and even death.
Do not take antibiotics without consulting a doctor. Improper use can lead to antibiotic resistance.
Don’t drink water or eat food that may have been contaminated with floodwater.
Don’t touch your eyes, nose, or mouth to prevent the bacteria from entering through your mucous membranes.

Conclusion

Leptospirosis is a serious public health concern in the Philippines, made worse by frequent flooding and inadequate flood control. The rising number of cases and deaths emphasizes the need for awareness, timely intervention, and above all, a proactive approach to protect yourself and your family from the threat of leptospirosis.
