Leptospirosis Cases Rise in Negros Occidental Following Typhoon Tino Floods

The Negros Occidental Provincial Health Office (PHO) has alerted the public to promptly seek medical evaluation if exhibiting symptoms of leptospirosis amid a notable increase in cases admitted at Corazon Locsin Montelibano Memorial Regional Hospital (CLMMRH) in Bacolod City. This rise in leptospirosis infections follows the extensive flooding triggered by Typhoon Tino (international name Kalmaegi) on November 4, which affected multiple areas across central and southern Negros.

In a statement released Monday, the PHO reiterated the Department of Health's warning that complications from leptospirosis can be life-threatening. They advised individuals exposed to contaminated water or soil to immediately contact emergency services via 1555 and press 2 for a free consultation.

Recent data from CLMMRH showed that as of 11 p.m. on November 23, there were 22 confirmed leptospirosis admissions, a significant increase from the initial eight cases reported earlier. Among these, 18 patients hail from southern Negros, while four are from Bacolod City, with ages ranging between 8 and 66 years old. Tragically, a child has succumbed to the disease.

Between November 1 and 22 alone, the hospital recorded 26 leptospirosis cases—double the 13 cases documented throughout October. This marks a stark contrast to previous months, which typically saw zero to two cases.

The regional hospital issued a public advisory over the weekend noting a rise in leptospirosis referrals, including moderate to severe conditions mostly from southern Negros Occidental. To manage the influx effectively, the hospital is prioritizing severe cases and has established dedicated wards for both adult and pediatric leptospirosis patients.

Meanwhile, in Isabela town, the Ignacio L. Arroyo Sr. Memorial District Hospital has urged residents who have come into contact with floodwaters to obtain prophylactic medication from nearby rural health units or hospitals. Hospital chief Dr. Gabby Palacios emphasized the recent surge in suspected leptospirosis cases and underscored the importance of protecting the community through timely intervention.

Health authorities continue to monitor the situation closely as they advocate for awareness and preventive measures against this potentially fatal disease.
