ABSTRACT

Background: acute respiratory infections are among the leading causes of morbidity and mortality worldwide.
Objective: to characterize acute respiratory infections in the context of the influenza pandemic in Cienfuegos province.
Methods: A case series study including 844 inpatients diagnosed with influenza-like illness, 806 suspected cases and 38 confirmed cases of pandemic influenza, was conducted. An analysis of the acute respiratory infections was performed, describing the pandemic in space and time. Suspected and confirmed cases were compared according to general variables, risk factors and interesting clinical features. Virus isolation and classification of confirmed cases considering source of infection and progress over time were showed. Data was collected from the Statistics Department of the Provincial Hygiene and Epidemiology Center and the inpatient database. Percentages, rates, the mean, standard deviation and Chi-square test with a 5 % margin of error were used.
Results: acute respiratory infections morbidity increased since 2008, largely because of the impact of the pandemic and the increased clinical and epidemiological surveillance. Its association with risk factors such as pregnancy, chronic diseases and traveling abroad was demonstrated. Circulation of the pandemic influenza virus with displacement of seasonal viruses and prevalence of indigenous cases were observed.
Conclusions: the characteristics of pandemic influenza in the province do not differ greatly from those described nationally and globally.
