埃尔摩罗峡谷病毒和石灰石峡谷病毒分布广泛，可能引起汉坦病毒肺综合征。为了增加我们的知识，汉坦病毒的地理分布与neotomine或sigmodontine啮齿动物在墨西哥，我们测试了876 cricetid啮齿动物捕获在18个墨西哥州（代表至少44种亚科Neotominae和10种亚科Sigmodontinae）的抗汉坦病毒IgG。在35只（4.0%）啮齿类动物中发现抗汉坦病毒抗体。5种抗体阳性啮齿动物的核苷酸序列数据表明，Sin Nombre病毒（美国汉坦病毒肺综合征[HPS]的主要病因）在墨西哥努埃沃州、圣路易斯波托西州、塔毛利帕斯州和韦拉克鲁斯州流行。然而，这些州尚未报告HPS，这表明在墨西哥东北部，HPS已与其他快速进展，危及生命的呼吸道疾病混淆。对其他19种抗体阳性啮齿动物的核苷酸序列数据的分析表明，El摩罗峡谷病毒和石灰石峡谷病毒在墨西哥的地理分布广泛。
El Moro Canyon virus and Limestone Canyon virus are widely distributed and may cause hantavirus pulmonary syndrome. To increase our knowledge of the geographic distribution of hantaviruses associated with neotomine or sigmodontine rodents in Mexico, we tested 876 cricetid rodents captured in 18 Mexican states (representing at least 44 species in the subfamily Neotominae and 10 species in the subfamily Sigmodontinae) for anti-hantavirus IgG. We found antibodies against hantavirus in 35 (4.0%) rodents. Nucleotide sequence data from 5 antibody-positive rodents indicated that Sin Nombre virus (the major cause of hantavirus pulmonary syndrome [HPS] in the United States) is enzootic in the Mexican states of Nuevo León, San Luis Potosí, Tamaulipas, and Veracruz. However, HPS has not been reported from these states, which suggests that in northeastern Mexico, HPS has been confused with other rapidly progressive, life-threatening respiratory diseases. Analyses of nucleotide sequence data from 19 other antibody-positive rodents indicated that El Moro Canyon virus and Limestone Canyon virus are geographically widely distributed in Mexico.
