out of 5 possible based on

Leishmaniasis- diseases caused by protozoa parasites - leishmania.

Specific carriers of Leishmania- small bloodsucking insects - mosquitoes.

Source of infection in the city- sick people and dogs. In the countryside - all sorts of rodents (gerbils, hamsters). The disease occurs in some areas of Turkmenistan and Uzbekistan, the Caucasus, is common in the states of Africa and Asia. Outbreaks of the disease are common from May to November - such seasonality is related to the biology of its carriers - mosquitoes. Especially high incidence among persons newly arrived in the endemic focus.

There are two main clinical forms of leishmaniasis: internal, or visceral, and dermal.

Internal leishmaniasis

Symptoms and course. A typical sign is a sharply enlarged spleen, along with an enlarged liver and lymph nodes. The temperature is remittent with two or three rises throughout the day. The incubation period lasts from 10-20 days to several months. The disease begins gradually - with increasing weakness, bowel disorder (diarrhea).Spleen and gradually increases to the height of the disease is enormous (in the lowered pelvis) and high density. Increases and liver. There are various types of rash on the skin, mostly papular. The skin is dry, pale earthy color. Typical tendency to bleeding, gradually develops cachexia (weight loss), anemia, edema.

Recognition of leishmaniasis. Accurate diagnosis can be made only later spleen or bone marrow puncture and finding in these organs Leishmania.

Anthroposis (urban type) cutaneous leishmaniasis

The incubation period of 3-8 months. Initially, a tubercle with a diameter of 2-3 mm appears at the site of the pathogen introduction. He gradually increases in volume, the skin over it becomes brownish-red, and after 3-6 months. covered with scaly crust. When removing it appears ulcer having a circular shape, smooth or wrinkled bottom covered with purulent coating. Infiltration appears around the ulcer, with the disintegration of which ulcers gradually increase in size, its edges are eroded, uneven, not detachable. Gradual scarring of the ulcer ends approximately one year after the onset of the disease.The number of ulcers from 1-3 to 10, they are traditionally located on open skin areas accessible to mosquitoes (face, hands).

Zoonotic (rural type) cutaneous leishmaniasis. The incubation period is shorter. A cone-shaped tubercle with a diameter of 2-4 mm appears on the site of the introduction of the pathogen, which quickly grows and in a few days reaches 1-1.5 cm in diameter, necrosis occurs in its center. After rejection of dead tissue, an ulcer opens, which expands rapidly. Single ulcers are sometimes very extensive, with a diameter of up to 5 cm or more. With multiple ulcers, and with all this type of leishmaniasis, their number can reach several tens and hundreds, the size of each ulcer is small. They have uneven, saped edges, the bottom is covered with necrotic masses and copious serous-purulent discharge. By 3 months, the bottom of the ulcer is cleared, granulations expand. The process ends after 5 months. Not often observed lymphangitis, lymphadenitis. In both types of cutaneous leishmaniasis, a chronic tuberculoid form resembling lupus may develop.

The diagnosis of cutaneous leishmaniasisestablished on the basis of a characteristic clinical picture, confirmed by the detection of the pathogen in the material taken from the nodule or infiltrate.
