PEDROZO, María Esther et al. Intensified surveillance of public health events in communities displaced by floods in Paraguay, 2015-2016. Rev. salud publica Parag. [online]. 2018, vol.8, n.2, pp.34-39. ISSN 2307-3349.


The importance of epidemiological surveillance of morbidity and mortality related to disasters is that it is essential to organize and manage resources, equipment and personnel necessary to respond effectively to emergencies. The implementation of an intensified surveillance system in populations displaced by flooding in the affected regions of Paraguay during the 2015/2016 period is described.

Materials and methods:

Descriptive study of cross section, between 12/28/2015 and 7/12/2016, throughout the national territory. As data sources, the planning of the daily notifications of diseases is used, the consolidation of the situation of the shelters. A web data loading system was designed. For the analysis of the data, it is the Epi Info 7.1.5 computer program, with measures of central tendency such as means, medians, and proportions.


68,699 affected people were registered. Of which, 32.4% were under 5 years old; 48.0% were housed in formal shelters and 36.7% in informal camps, both of which identified a deficit of basic sanitary conditions. There were 23,877 queries. The most frequent diseases: Acute respiratory infection, pneumonia (33%), hypertension (19%), influenza-like illness (14%), skin lesions (6%) and diarrhea (6%). 3% corresponded to the acute febrile syndrome, two confirmed cases of leptospirosis. There were no outbreaks of infectious diseases.


The implementation of intensified surveillance during the flooding event allowed a better understanding of the general situation of the displaced population, as well as the identification of risk groups and their most frequent health problems. This was instrumental in guiding the prevention and control efforts during the disaster.
