What does visceral leishmaniasis do?
Visceral leishmaniasis, the most severe form of leishmaniasis also known as kala-azar, is a life-threatening disease caused by Leishmania parasites which are transmitted by female sandflies. Visceral leishmaniasis causes fever, weight loss, spleen and liver enlargement, and, if not treated, death.

Visceral leishmaniasis (VL), also known as kala-azar is fatal if left untreated in over 95% of cases. It is characterized by irregular bouts of fever, weight loss, enlargement of the spleen and liver, and anaemia.
What are the clinical features of visceral leishmaniasis?
American visceral leishmaniasis (AVL) is a systemic protozoan infection characterized by fever, malaise, adynamia, and weight loss, besides splenomegaly, hepatomegaly, anemia, leukopenia, pancytopenia, and hypergammaglobulinemia.
Is leishmaniasis a virus or bacteria?
What is leishmaniasis? Leishmaniasis is a parasitic disease that is found in parts of the tropics, subtropics, and southern Europe. Leishmaniasis is caused by infection with Leishmania parasites, which are spread by the bite of infected sand flies. There are several different forms of leishmaniasis in people.
How long does leishmaniasis last?
Skin lesions may change in size, becoming smaller but often enlarge and do not heal. Sores may be moist and leak fluid (like pus) or may be dry and crust over, and are usually painless. Individuals may develop lesions that are limited to one area of the body and may slowly heal on their own over 6-18 months.
How do you control leishmaniasis?
Spray living/sleeping areas with an insecticide to kill insects. If you are not sleeping in a well-screened or air-conditioned area, use a bed net and tuck it under your mattress. If possible, use a bed net that has been soaked in or sprayed with a pyrethroid-containing insecticide.
What is the life cycle of leishmaniasis?
Life Cycle: Leishmaniasis is transmitted by the bite of infected female phlebotomine sand flies. The sand flies inject the infective stage (i.e., promastigotes) from their proboscis during blood meals .
What are the signs of leishmaniasis?
The signs of Leishmaniasis reflect the distribution of the parasite. They commonly include skin problems (especially around the head and pressure points), enlarged lymph nodes and spleen, eye problems, weight loss, lethargy, reduced appetite, nose bleeds and vomiting and diarrhoea.

Is Leishmania contagious?
Leishmaniasis is not contagious person to person. Sand fly bites are necessary to transfer the parasite from the sand fly to the human. The sand fly is the vector for the disease. The protozoan parasite has a life cycle that requires development in both the sand fly and a mammal (human, dogs and others).
Is there a cure for visceral leishmaniasis?
Visceral leishmaniasis (VL), which reflects dissemination of Leishmania parasites throughout the reticuloendothelial system, is potentially life threatening without treatment (Figure 3). VL is an opportunistic infection in persons with human immunodeficiency virus (HIV)/AIDS or other causes of cell-mediated immunosuppression.
Is the visceral leishmaniasis the same as the cutaneous disease?
(This disease is not the same as cutaneous leishmaniasis, a milder disease caused by another protozoan of the Leishmania genus which also causes skin lesions.) Two species of Leishmania are known to give rise to the visceral form of the disease.
