A total of 4,626 mammals were serologically tested for antibodies to Sin Nombre virus. All nonrodent species were antibody negative. Among wild rodents, antibody prevalence was 8.5% in murids, 1.4% in heteromyids, and < 0.1% in sciurids. Of 1,921 Peromyscus maniculatus (deer mice), 226 (11.8%) were antibody positive, including one collected in 1975. The highest antibody prevalence (71.4% of 35) was found among P. maniculatus on Santa Cruz Island, off the southern California coast. Prevalence of antibodies among deer mice trapped near sites of human cases (26.8% of 164) was significantly higher than that of mice from other sites (odds ratio = 4.5; 95% confidence interval = 1.7, 11.6). Antibody prevalence increased with rising elevation (> 1,200 meters) and correlated with a spatial cluster of hantavirus pulmonary syndrome cases in the Sierra Nevada.
总共对4626只哺乳动物进行了血清学检测,以检测其是否含有针对辛诺柏病毒的抗体。所有非啮齿类动物的抗体检测均为阴性。在野生啮齿动物中,家鼠科动物的抗体阳性率为8.5%,更格卢鼠科动物为1.4%,松鼠科动物则小于0.1%。在1921只白足鼠(鹿鼠)中,有226只(11.8%)抗体呈阳性,其中包括1975年采集的一只。在南加利福尼亚海岸外的圣克鲁斯岛上的白足鼠中,抗体阳性率最高(35只中有71.4%)。在人类病例附近捕获的鹿鼠中,抗体阳性率(164只中有26.8%)显著高于其他地点捕获的小鼠(优势比=4.5;95%置信区间=1.7, 11.6)。抗体阳性率随海拔升高(>1200米)而增加,并且与内华达山脉汉坦病毒肺综合征病例的空间聚集相关。
