DESCRIPTION OF CASES OF DENGUE, ZIKA VIRUS, CHIKUNGUNYA AND URBAN YELLOW FEVER IN THE AMAZONAS: A 5-YEAR RETROSPECTIVE LOOK

Abstract

Introduction: Among the main viral infectious diseases that have become more frequent in Amazonas, the most prominent are dengue, zika, chikungunya and also urban yellow fever, caused by the Aedes Aegypti mosquito. All these pathologies present very similar symptoms, such as intense headache and myalgia, high fever and nausea. Objective: To describe a retrospective five-year period of the occurrence of cases of arboviruses of urban occurrence (dengue, zika virus, chikungunya and yellow fever) in Amazonas. Methodology: This is a retrospective, descriptive study with a quantitative approach using existing public data from Sinan/Net for the years 2019 to 2023. Result: In the five-year period (2019 to 2023), 65,580 cases of urban arbovirus infections (dengue, Zika, Chikungunya) were recorded in the state of Amazonas, with 2023 being the period with the highest number of records of these pathologies (19,396 cases = 29.5%). Severe dengue, which required hospitalization, was the most common infection (65.7% of cases), followed by Chikungunya infection (2.5%) and Zika virus (1.8%). Yellow fever, even though it is considered a rare event, there were 8 records of cases (0.01%) in the period. Conclusion: Prevention is the best way to fight the disease. The best way to prevent dengue fever is to prevent the proliferation of the Aedes Aegypti mosquito, eliminating stored water that can become possible breeding grounds
