October 11, Colombo (LNW): Health authorities have issued a public warning over the increasing threat of leptospirosis in several parts of Sri Lanka, particularly with the onset of agricultural activities linked to the Maha cultivation season.
The Epidemiology Unit of the Ministry of Health has identified 12 districts as high-risk zones, where conditions are currently favourable for the spread of the disease.
The districts listed include Galle, Ratnapura, Kalutara, Kegalle, Kurunegala, Matara, Hambantota, Anuradhapura, Polonnaruwa, Badulla, Gampaha, and Monaragala.
These areas, many of which are heavily dependent on paddy cultivation and other forms of agriculture, see increased exposure to waterlogged environments—a key factor in the transmission of leptospirosis.
Leptospirosis, commonly known as rat fever, is a bacterial infection typically spread through water contaminated by the urine of infected animals, particularly rodents. Farmers, field workers, and individuals engaged in outdoor labour are particularly vulnerable during the rainy season.
Dr Thushani Dabarera, Consultant Epidemiologist at the Epidemiology Unit, revealed that nearly 8,000 cases were reported across the island last year, underscoring the need for heightened awareness and preventive action as the new farming season begins.
In response to the escalating risk, a national steering committee has been formed to coordinate prevention and control efforts. Health officials are working with local authorities to distribute protective medication and raise public awareness, especially among farming communities.
Those involved in agricultural work are being strongly advised to obtain prophylactic antibiotics from their nearest public health inspector (PHI) or Medical Officer of Health (MOH) office. Wearing protective gear, such as boots and gloves, and avoiding direct contact with contaminated water can also significantly reduce the risk of infection.
The Ministry of Health has called on the public to take the threat seriously and to seek medical attention promptly if symptoms such as fever, muscle pain, or chills occur after working in wet or muddy conditions. Early diagnosis and treatment are critical to preventing severe complications associated with the disease.
