Everglades virus (EVEV), an enzootic subtype of Venezuelan equine encephalitis virus, along with its endemic mosquito vector, , is known only from South Florida. The taxonomy of is complex and was once synonymous with and . We modeled potential distribution of in Florida and the Caribbean using an ecological niche model and compared this distribution to the recorded distribution of EVEV in Florida as well as historical records of /. We used recent collections and occurrence data from scientific publications and temperature/precipitation variables and vegetation greenness values to calibrate models. We found mean annual temperature contributed the greatest to model performance. Everglades virus in humans and wildlife corresponded with areas predicted suitable for in Florida but not with incidence of antibodies reported in dogs. Most records of / in the Caribbean did not correspond to areas predicted suitable for , which may be due to mean annual temperature values in the Caribbean exceeding values within the calibration region, imposing model constraints. Results indicated that this model may adequately predict the distributions of within Florida but cannot predict areas suitable in the Caribbean.
佛罗里达州和加勒比地区伊蚊病毒的潜在分布与佛罗里达州everglades 病毒的记录分布以及/的历史记录进行了比较。我们使用最近的收集和科学出版物中的发生数据以及温度/降水变量和植被绿色值来校准模型。我们发现，年平均温度对模型性能的贡献最大。人类和野生动物中的佛罗里达州伊蚊病毒与预测适合佛罗里达州伊蚊的区域相对应，但与犬只报告的抗体发病率无关。加勒比地区/的大多数记录与预测适合的区域不对应，这可能是由于加勒比地区的年平均温度值超过了校准区域内的温度值，从而限制了模型的应用。结果表明，该模型可以很好地预测佛罗里达州内的分布，但不能预测加勒比地区适合的区域。
