Health Warning Issued for Leptospirosis Risk in Flooded Areas of Ratchaburi

On October 19, 2026, Dr. Pajaree Areerob, the Ratchaburi Provincial Public Health Officer, issued a public health advisory for residents in flood-affected areas, particularly in the Photharam district. Following nearly two weeks of stagnant, foul-smelling floodwaters, officials are concerned about the increased risk of waterborne illnesses.

According to the report from Khaosod Online, the primary concern is the spread of leptospirosis, a bacterial infection that can be contracted through contact with contaminated water, especially if individuals have open wounds on their feet. Health authorities emphasize that prolonged exposure to floodwater significantly increases the risk of skin infections and leptospirosis.

Residents and visitors in affected areas are advised to wash their feet thoroughly with soap after any contact with floodwater and to regularly inspect their skin for wounds. The health department has explicitly warned that anyone who has been exposed to floodwaters and subsequently develops a high fever or experiences unusual pain in their calves should seek medical attention immediately for a blood test. Early diagnosis is considered critical for effective treatment. While this warning is specific to the current situation in Ratchaburi, it serves as a general reminder for those in any flood-prone region of Thailand to exercise caution. It remains to be confirmed how many cases have been officially diagnosed in the area to date.
