摘要
利什曼原虫可引起皮肤、粘膜皮肤和内脏（黑热病）的利什曼病。每年大约有1千万例皮肤利什曼病和40万例内脏利什曼病。吸血白蛉可传播利什曼病，从被感染的动物传播给人或从人传播给人。注射药物的设备可传播内脏利什曼病。由于生态学的改变，利什曼病例在多数疫区越来越多。
Leishmania parasites cause cutaneous, mucocutaneous and visceral （kala-azar） leishmaniasis. There are about 10 million cases of cutaneous leishmaniasis and 400,000 cases of visceral leishmaniasis per year. Phlebotomine sandflies transmit leishmaniasis, either from infected animals to humans or from person to person. Injecting drug equipment can transmit visceral leishmaniasis. Leishmaniasis is increasing in most endemic areas as a result of ecological change.
