The author presents the analysis of cases of malaria acknowledged as occupational diseases in soldiers in the period of 1996–2006. In almost all cases, soldiers were infected in the region of tropical Africa in the course of an observatory mission of the Organization of United Nations. Occupational diseases were acknowledged in twenty four cases. Plasmodium falciparum was the most frequently diagnosed species. The average time from engagement to manifestation of the disease was 7.3 months. Serological examinations resulted in positive findings of IgG antibodies in 20 soldiers. The findings were negative only in 9 soldiers (i. e. in 45% of examined soldiers). The author underlines the importance of health documentation on diagnostics and treatment of malaria in the place of engagement and a limited significance of the serological examination for the purpose of acknowledgment of the occupational disease.
