Abstrakt:	Introduction: Dengue is a disease transmitted by mosquitoes of the Aedes genus; this has presented a historical increase in cases in South America, which represents a public health problem. From the Febrile Emergency Unit (UFU) of Hospital Muñiz, the laboratory results were analyzed and the circulating serotype was identified at the level of the Autonomous City of Buenos Aires (CABA), confirming the proportion of indigenous cases, recording symptoms and epidemiology. The objective of this analysis is to highlight the increase in indigenous cases of dengue in CABA. Methods: An observational and retrospective study was carried out, from January 1 to May 8, 2023, of the positive PCR results for dengue. Results: 1159 patients with febrile symptoms were assisted, of which 554 (47.7%) were probable cases while the remaining 542 (46.7%) were febrile syndromes of another etiology. Of the probable cases, 162 with positive PCR results (29%) were evaluated, of which 18 (11%) were imported and 144 (89%) native. DENV-2 predominated (86% of confirmed cases). The clinical manifestations were fever (100%), myalgia (100%), headache (98%), arthralgia (87%), nausea (46%), and retroocular pain (39%). Discussion: For 10 years, there has been an increase in the number of indigenous dengue cases in CABA. In the analysis of this article, autochthonous dengue appears as an outbreak at the city level. Notification of the clinic and epidemiology is important to consider public health strategies in the fight against dengue and possible new studies related to outbreaks and epidemics.
