Abstract:
Zika virus (ZIKV) is a mosquito-borne viral disease associated with fetal microcephaly and other central nervous system (CNS) symptomatology. It was first identified in a Rhesus macaque in Uganda in 1947 and later in humans (Zika fever). In 2015, ZIKV was notified in Northeast Brazil where it was associated with CNS alterations and with rapid epidemic spread. Considering that ZIKV infects Old World monkeys, the aim of this study was to follow its potential in neotropical primates. Here, we show the detection of ZIKV in marmosets and capuchin monkeys captured in Ceara state, Northeast Brazil. Nine (9/132) samples were positive by quantitative RT-PCR assay. Neutralizing antibodies in primates for ZIKV were also detected by PRNT. The ZIKV-positive samples were obtained from peridomestic animals captured in proximity to humans in areas with reports of ZIKV-associated microcephaly cases during the epidemic period. These results reiterate the molecular evidence of ZIKV infection in neotropical primates, and the temporal detection suggests that detection in primates occurred during the epidemic period in humans. However, a continuous surveillance is necessary to exclude the possibility of virus circulation and transmission in wild environments.
