In early 1985, the Parakana-Apiterewa, a small, primitive Indian tribe, was contacted in the southern Amazon Basin. The tribe was thought to have been totally isolated from civilization until recent development of their land. Blood specimens were collected in 1985, shortly after the discovery of the tribe, and analyzed for the presence of rhinovirus-neutralizing antibody to nine different immunotypes. Six to forty-seven percent of the serum samples tested contained antibody to at least one immunotype of rhinovirus. The prevalence of rhinovirus antibody in the Parakana-Apiterewa Indians was similar to that reported in United States populations, suggesting that there had been considerable direct or indirect contact in the past between tribe members and persons in the outside world.
1985年初，帕拉卡纳 - 阿皮特雷瓦这个小型原始印第安部落，在亚马孙盆地南部被发现。人们认为该部落此前一直与文明社会完全隔绝，直到其土地近期得到开发。1985年，就在该部落被发现后不久，便采集了血液样本，并对其针对九种不同免疫型的鼻病毒中和抗体进行了分析。检测的血清样本中，有6%至47%含有针对至少一种鼻病毒免疫型的抗体。帕拉卡纳 - 阿皮特雷瓦印第安人中鼻病毒抗体的流行率与美国人群中报告的流行率相似，这表明该部落成员与外界人员过去曾有过大量直接或间接接触。
