Recent seroprevalence studies in animals detected Rocio virus in regions of Brazil, indicating risk for re-emergence of this pathogen. We identified Rocio virus RNA in samples from 2 human patients for whom dengue fever was clinically suspected but ruled out by laboratory findings. Testing for infrequent flavivirus infections should expedite diagnoses.

2011-2013年，巴西登革热流行期间检测到轮状病毒SPH 34675

最近在动物中进行的血清阳性率研究在巴西地区发现了罗西奥病毒，表明该病原体可能再次出现。我们在2名人类患者的样本中鉴定了Rocio病毒RNA，他们在临床上怀疑有登革热，但实验室检查结果排除了登革热。测试不常见的黄病毒感染应加快诊断速度。
