MAKATI CITY — Heavy rains sweeping across Metro Manila have brought flooding and disruption, but they have also increased concerns over leptospirosis, a serious disease associated with contaminated floodwater. The Department of Health (DOH) reported 6,253 leptospirosis cases and 378 deaths nationwide from January 1 to August 29, 2026. Floodwater can become contaminated with the urine of infected animals, particularly rats, allowing the bacteria to enter the body through open wounds or through the eyes, nose, and mouth. Although leptospirosis can become severe, it is both preventable and treatable when addressed early. Makati City continues to take steps to protect its residents, while individuals can also reduce their risk by knowing the warning signs and following basic precautions.
Know the Warning Signs
Early recognition of leptospirosis can make a crucial difference. Symptoms may appear suddenly between two and 30 days after exposure to contaminated water. Common symptoms include high fever, severe headache, chills, and muscle pain, particularly in the calves, thighs, and lower back. Some people may also experience red or bloodshot eyes, nausea, vomiting, and abdominal pain. In serious cases, the infection can result in jaundice, characterized by yellowing of the skin and eyes, as well as kidney damage and other potentially life-threatening complications. Anyone experiencing these symptoms after floodwater exposure should seek medical attention immediately.
After Floodwater Exposure, Act Quickly
The DOH advises people who have been exposed to floodwater to consult a healthcare professional as soon as possible, even if they do not have visible wounds. Those who have waded through or otherwise come into contact with floodwater are encouraged to visit the nearest health center, hospital, or YAKAP Clinic for proper assessment. A healthcare professional can determine whether preventive treatment, such as doxycycline, is appropriate. Doxycycline is a prescription antibiotic and should not be taken without medical advice because it may not be suitable for everyone. Anyone who develops fever, muscle pain, headache, or other symptoms following floodwater exposure should not wait for the condition to worsen before consulting a doctor.
Prevention Starts With Awareness
The safest way to avoid leptospirosis is to stay away from floodwater whenever possible. Residents should avoid bathing, playing, or walking in flooded areas. When wading through floodwater cannot be avoided, wearing waterproof boots and other protective equipment can help reduce exposure. Cuts and open wounds should also be covered with waterproof bandages to prevent contaminated water from coming into contact with them. Residents are likewise encouraged to follow health advisories issued by the DOH and Makati City Government for updated safety information. By remaining informed, taking precautions, and seeking medical attention promptly after possible exposure, Makati residents can help protect themselves, their families, and the wider community from leptospirosis.
