Introduction: Arboviral diseases have a high incidence and constitute a permanent threat to health globally.
Objective: Characterize from the epidemiological perspective patients with clinical suspicion and diagnosis of arbovirus in Granma province during 2019.
Methods: An observational, descriptive, cross-sectional study was conducted in the period between January 1st and December 31st, 2019. The variables studied were: age, sex, municipalities, ways of identifying signs and symptoms, dengue positivity and months of study of patients.
Results: In the cases studied due to suspicions, 41.43 % belonged to Bayamo municipality and 51.85 % (9180) were female patients. The predominant age range was ≤ 20 years (n = 8340; 47.10 %). In 87.07% (15417) of patients, the identification of signs and symptoms suggestive to arbovirus was through investigations. Dengue positivity was found in 25.00% of patients (4427), of which 53.87% (2385) were female patients. The age range most affected by arbovirus was 41-60 (n = 1422; 32.12%). September was the month with the highest number of cases both studied by suspicions (n = 3720; 21.01%) and confirmed with dengue (n = 1341; 30.29%). In the province, the incidence rate of dengue was 54.0 per 10,000 inhabitants.
Conclusions: The importance of the investigations as a method to identify signs and symptoms suggestive to arboviral diseases was evidenced. The calculated incidence rates indicated the most affected territories by dengue, which constitutes a starting point for the implementation of health strategies focused on arboviral prevention.
