RESTREPO, Berta Nelly et al. Importance of clinical and laboratory characteristics in the diagnosis of dengue and chikungunya co-infection: Probable case report. Biomed. [online]. 2020, vol.40, n.3, pp.472-478.  Epub 30-Jun-2020. ISSN 0120-4157.  https://doi.org/10.7705/biomedica.5085.

We report the case of a 38-year-old woman who initially consulted for an undifferentiated fever. Although her clinical condition evolved with signs and symptoms compatible with dengue with alarm signs and that the anti-dengue IgM detection in a single sample indicated it was a probable case that could have happened during the previous three months, the patient kept consulting due to little improvement.

On the tenth day after the onset of symptoms, she presented with painful polyarticular symmetric edema, as well as hyperpigmented lesions in the nasolabial fold. Chikungunya diagnosis was confirmed by the presence of IgM antibodies. In endemic countries for dengue and chikungunya, the possibility of co-infection exists, but it may go unnoticed. On the other hand, the co-infection may worsen the clinical course of these diseases. Therefore, physicians should evaluate the clinical and laboratory characteristics of both infections to be able to diagnose the coinfection for adequate management and to minimize complications.
