LEPTOSPIROSIS CASES JUMP AFTER FLOODING
The Department of Health recorded 8,317 leptospirosis cases from January 4 to September 5, 14 percent more than during the comparable period last year. The sharpest warning is in the recent trend: 2,374 cases were reported from August 9 to 22, more than four times the number in the previous two weeks.
The DOH recorded 457 deaths. That is lower than the 772 reported during the comparable period in 2025, but it still means hundreds of families lost someone to a disease that often follows contact with floodwater contaminated by animal urine. Metro Manila had the highest number of cases, followed by Central Luzon and Calabarzon.
Leptospirosis may begin with fever, severe headache, muscle pain, red eyes, chills or vomiting. A person who walked through floodwater should not wait for yellow skin, kidney problems or other severe symptoms before seeking medical advice. Preventive antibiotics are not for everyone and should be taken only after assessment by a health professional.
WHAT TO WATCH
New DOH surveillance figures after the latest floods, local announcements on free consultation or preventive treatment, and symptoms appearing within days or weeks of flood exposure.
