9 deaths, 376 leptospirosis cases recorded in Cagayan; Lasam has the highest number

TUGUEGARAO CITY, Cagayan — Nine people have died and 376 cases of leptospirosis have been recorded in Cagayan from January 4 to September 26, 2026, according to the latest surveillance report of the Cagayan Provincial Health Office (PHO).

The PHO report, released on October 5, showed that the province’s 376 cases were down by 57, or 13.2 percent, from the previously reported 433 cases.

Despite the decline in cases, the nine recorded deaths underscore the continuing health risk posed by leptospirosis, particularly among people exposed to contaminated floodwater, mud and soil.

Lasam records most cases

Lasam recorded the highest number of leptospirosis cases in the province with 46, followed by Gattaran with 42, Baggao with 35 and Allacapan with 29.

The concentration of cases in these municipalities highlights the continuing need for residents to take precautions, particularly during and after flooding and heavy rainfall.

Leptospirosis is a bacterial disease that can be contracted through contact with water or soil contaminated with the urine of infected animals, particularly rats. The risk increases when people wade through contaminated floodwater, especially when they have open wounds or cuts.

National cases up 49 percent

The Cagayan figures come amid an increase in leptospirosis cases nationwide.

The Department of Health recorded 12,654 cases and 664 deaths from January 4 to September 30, 2026, compared with 8,511 cases and 899 deaths during the same period in 2025.

This represents a 49 percent increase in cases, although deaths declined by 26 percent. The national case fatality rate also fell from 10.56 percent to 5.25 percent.

PHO urges early consultation

The Cagayan PHO urged residents who develop symptoms associated with leptospirosis, particularly after exposure to floodwater or muddy areas, to seek immediate medical attention at the nearest health facility.

Residents were also advised to avoid unnecessary contact with floodwater and mud, particularly during heavy rains and flooding, and to keep wounds and cuts protected from potentially contaminated water.

Early consultation and treatment are important because leptospirosis can become severe and may lead to complications affecting the kidneys, liver and other organs.
