Abstract
RAMIREZ-ORREGO, Lourdes et al. First report of a dengue outbreak in balsas, Amazonas, Peru, during 2021 and 2022. Rev. Fac. Med. Hum. [online]. 2023, vol.23, n.3, pp.28-34. Epub Sep 21, 2023. ISSN 1814-5469. http://dx.doi.org/10.25176/rfmh.v23i3.5846.
Introduction:
The increase in dengue cases in Amazonas represents a public health risk. In 2021, Balsas reported a dengue outbreak for the first time.
Methods:
The population included patients who met the case definition between December 2021 and February 2022. Serotype identification was determined using a multiplex qRT-PCR.
Results:
A total of 72 patients were identified, of which 53 (74%) were confirmed by serology (NS1 Ag). The prevalent serotype was DENV-2 (94%), and 6% were DENV-1. Patients aged 19 to 45 years had the highest percentage of cases (59%). The most frequent symptoms were headache, myalgia, fever, and arthralgia; 23% had intense abdominal pain.
Conclusion:
This was the first confirmed dengue outbreak in the Balsas district, with DENV-2 being the main cause of the outbreak, highlighting the need to improve surveillance in areas without autochthonous transmission of the disease.
