Abstract
RW Ashford JA Rioux Lama Jalouk Aida Khiami C Dye Evidence for a longterm increase in the incidence of Leishmania tropica in Aleppo Syria Transactions of The Royal Society of Tropical Medicine and Hygiene Volume 87 Issue 3 MayJune 1993 Pages 247–249 https//doiorg/101016/0035920393901113We report the results of a short study of the epidemiology of Leishmania tropica in the Sheikh Maksoud District of Aleppo Syria The present and past status of infection in a community of about 100 000 people are assessed from prevalence and incidence data obtained by active and passive case detection and from a skin test survey L tropica has apparently been endemic for at least 2–3 human generations in Aleppo and incidence has increased over the past decade The current estimated force of infection is 0·0174/year the incidence is about 5 and the average age of infection is 14 years L tropica has the essential characteristics of a cyclic infectious disease and the recent rise in incidence could be part of a long period cycle A survey of leishmanial scars seriously underestimated the fraction of persons immune as scar surveys usually do We estimate that a passive case registration scheme which has been established in response to growing concern about leishmaniasis in Aleppo succeeds in recording and treating about one in 4 cases
