Epidemiological comments Active serological surveillance for antibodies against leishmaniosis of free-roaming dogs was carried out. Out of 116 dogs which have been tested, only 3 dogs have detectable levels of antibodies against leishmaniosis with the IDEXX test kit or IFAT. No additional positive cases have been detected since 1 Sep 2020. These findings suggest that the seroprevalence of canine leishmaniosis in the local free-roaming dog population is low. There continues to be no reports in the local owned dog population. Annual targeted active surveillance and passive surveillance of dogs for leishmaniosis, and vector surveillance, will continue.
