[Visceral leishmaniasis as a threat for non-endemic countries].
Global warming, globalisation, and constantly increasing number of people involved in long-distance tourism and travel to exotic destinations are likely to increase the number of cases of exotic diseases "imported" to nonendemic countries. One of the often forgotten and neglected diseases has been visceral leishmaniasis (VL or kala-azar). The disease is endemic to 62 countries, with India and Sudan accounting for the majority of the cases. It is typically fatal if left untreated. Each year about 500 000 new cases are reported worldwide, and 50 000 die as a result of the disease. Kala-azar is present in the Mediterranean Europe and 70% of cases are imported to non-endemic countries of European Union from that area. Immunocompromised status of patients, like HIV carriers are the principal prospective target for kala-azar. HIV/VL-coinfected patients have significantly higher relapse rates and decreased life expectancy. There is no formal system of reporting imported cases in Europe, except from Germany. In non-endemic countries, including Poland, there is usually the substantial delay between the onset of symptoms and the final diagnosis, with an average exceeding 3 months. This fact suggests that physicians are not familiar with leishmania infections. Despite progress in vaccine development, the only way to prevent the infection is avoiding sandfly bites. Mosquito nets, wearing appropriate clothes and repellents containing DEET (diethyl toluamide) can reduce number of bites and protect also from the other vector-borne diseases like malaria or dengue. Education concerning kala-azar risk and ways of the disease prevention is a needed for tourists and the other travelers.
