Oropouche Virus Detection in Febrile Patients’ Saliva and Urine Samples in Salvador, Bahia, Brazil
Oropouche virus (OROV) is a negative-sense, single-stranded RNA arbovirus transmitted to humans by the midge Culicoides paraenesis, causing Oropouche fever.

| description | Oropouche virus (OROV) is a negative-sense, single-stranded RNA arbovirus transmitted to humans by the midge Culicoides paraenesis, causing Oropouche fever. Reports of its outbreak in Brazil have so far been restricted to the Central-Northern region of the country. However, its incidence is underestimated, mainly due to its clinical similarities with other arbovirus diseases, including dengue (DENV), chikungunya (CHIKV), and zika (ZIKV), and the lack of specific diagnostic tests. Here, we report for the first time, the detection of OROV in saliva and urine samples, and cases of autochthone OROV infections in Salvador Metropolitan region, Bahia, a Northeastern capital in the coast of Brazil. Serum, saliva, and urine samples negative for DENV, CHIKV, and ZIKV were tested for OROV using a reverse transcription nested polymerase chain reaction (RT-nested-PCR) protocol, and 2 serum, 2 saliva, and 1 urine samples were positive. This report shows the need for an efficient surveillance system for controlling the spread of this virus, and suggests the use of saliva and urine as alternative samples for OROV detection in the absence of serum samples. |
