Abstract

This paper describes the characteristics of an outbreak of salmonellosis among the students from one primary school in Belgrade, which took place in the period 1013.05.2018. year. In this paper, we used the descriptive and analytical methods. Data sources for an outbreak of salmonellosis were informationson epidemiological research and results of microbiological research from the Institute of Public Health of Belgrade. Data from outbreaks of salmonellosis were collected from targeted epidemiological questionnaire. In total, 49 people (48 students and one teacher) were affected by an outbreak, 'the rate of occurrence' in this outbreak amounted to 64.5%. The incubation period in patients ranged from 782 hours. 'The rate of occurrence' for male was 60.5% and for female 68.4%. The sick students were aged 910 years. A significant relative risk was obtained for the two types of food consumed: veal soup with vegetables (RR 1.6, 95% CI: 1.05 to 2.55) and cabbage salad (RR 1.6, 95% CI: 1.06 to 2.40). The source of infection was not detected. The presumed pathway of infections in this outbreak was the food consumes on May 9, 2018. year as a lunch on a oneday excursion.
