RESUMEN
The author describes a protracted epidemic of measles in the district of Liptovský Mikulás in the Central Slovakian region where between May 5, 1988 and July 11, 1988 30 children, mosth of them not immunized against measles, mostly from the gipsy community in Vazec contracted the disease. The infection was introduced to the community by a child which acquired measles in the Infectious Department in Liptovský Mikulás where from April 26, 1988 several students of the Military School in Liptovský Mikulás were isolated mostly with diagnose of exanthematous diseases, ex post confirmed as measles. The students came from different parts of Czechoslovakia and the first cases developed in two students after their return from the Easter holidays from different regions in the Czech Republic. Measles were not suspected up to June 20, 1988 when in the gipsy community there were already 12 cases of measles and 12 students from the military school were in hospital. This led to the spread of infection of two otherwise separate localities. The epidemiological connection between the disease of students of the military school and the other patients was elucidated at the end of June, when the epidemic was almost over.
