Cases of human and equine West Nile virus (WNV) disease reported in Texas in 2002 were analyzed to assess their temporal relationship. For each human case with a known residential location, the closest equine case (within a 5 km radius) was selected. A total of 80 human-equine case pairs were identified, 51 (64%) of which were located in urban areas. Dates-of-onset of human and equine cases were positively correlated (r(SP)=0.494, P<0.001). Although overall there was no significant (P=0.207) difference between the dates-of-onset of human and equine cases, in urban areas of Texas equine cases were reported significantly (P=0.011) earlier (August 7) than corresponding human cases (August 19). Monitoring equine populations that are susceptible to WNV disease within close proximity to urban human populations might be useful for predicting disease risk in human populations.
对2002年在得克萨斯州报告的人类和马的西尼罗河病毒（WNV）病病例进行了分析，以评估它们的时间关系。对于每个已知居住地点的人类病例，选择距离最近的马病例（在半径5公里范围内）。总共确定了80对人-马病例，其中51对（64%）位于城市地区。人类和马病例的发病日期呈正相关（r(SP)=0.494，P<0.001）。虽然总体上人类和马病例的发病日期没有显著差异（P=0.207），但在得克萨斯州的城市地区，马病例的报告时间（8月7日）明显早于相应的人类病例（8月19日）（P=0.011）。在城市人群附近监测易感染西尼罗河病毒病的马群，可能有助于预测人类人群的疾病风险。
