title: Malaria as an Occupational Disease in Polish Citizens.
abstract: Background: Since 1963, malaria has been exclusively recognized in Poland as an imported disease, which has become increasingly frequent in recent years. When associated with performing duties in malaria-endemic areas, malaria is acknowledged as an occupational disease. Methods: Ninety five cases of malaria recognized as an occupational disease in Polish citizens in the years 1984-1993 were studied retrospectively in terms of working conditions, epidemiologic and clinical features, and permanent disability sequelae. Results: Among patients examined, young and professionally active persons who called at tropical ports or who worked in rural areas or in the regions of military conflict were predominant. Most infections were contracted in Africa during the first few months of the stay. The observed morbidity and recrudescence rates were mainly attributable to Plasmodium falciparum. Disregard of prevention and chemoprophylaxis of malaria were key risk factors. In 33% of the patients, severe symptoms and complications occurred and these required long-term therapy. In seven cases, disturbances of the central nervous system, hepatic, renal, or cardiac system occurred 6 months after termination of treatment, and these occurrences resulted in permanent disability and an inability to work. Conclusions: The disability and inability to work and its legal consequences, such as indemnity, demonstrate that malaria may present a serious socioeconomic problem, even in the country where it is an imported disease.
