Epidemic of cutaneous leishmaniasis: 109 cases in a population of 500.

In February 2004, 4 patients aged 10-15 years presented at the Pakistan Institute of Medical Sciences with non-healing multiple ulcers on exposed parts. On the basis of history, clinical assessment and fine needle aspiration cytology, they were diagnosed as having cutaneous leishmaniasis. We were informed that several similar cases were present in their village. A team of doctors and technicians visited the area. A survey was conducted and another 105 cases with various morphological presentations were identified. The area was visited several times to find the vector, reservoirs and source of infection and to advise on controlling the epidemic.
