transmitted by sand flies


Canine visceral leishmaniosis is caused by Leishmania infantum, a pathogen transmitted by phlebotomine sand flies. The transmission mainly occurs when these small (2mm) flies bite and take blood from dogs or humans. Other routes of transmission are possible including reproduction and blood transfusion. In dogs, the clinical signs of this disease are very complex: general signs such as fever, weakness, loss of appetite and weight loss, skin lesions, eye problems, renal issues. When dogs are affected by leishmaniosis, the signs may take several months or even years to appear. During this subclinical phase, dogs are easier to manage for the veterinarian. That’s why early detection is crucial. The treatment is long-life, to improve life’s quality and expectancy. 

As leishmaniosis is easier to prevent than to treat, recommendations, especially in endemic areas, have been established: 

• The combination of a repellent parasiticide with proven efficacy against sand flies all year round, plus considering vaccination as advised by your veterinarian.

• Reduce sand flies favorite developing sites near your home, such as organic material like compost, bins, woodpiles.

• Keep your dog indoor from dusk to dawn.

Geographical distribution

Canine leishmaniosis is mainly present in warm zones where the insect vectors are active. The geographical distribution is constantly evolving on the world map, with the emergence of new endemic and peri-endemic areas because of globalization and climate changes.
