Coccidioidomycosis (also called Valley fever) is caused by a soilborne fungus, Coccidioides spp., in arid regions of the southwestern United States. Though some who develop infections from this fungus remain asymptomatic, others develop respiratory disease as a consequence. Less commonly, severe illness and death can occur when the infection spreads to other regions of the body. Previous analyses have attempted to connect the incidence of coccidioidomycosis to broadly available climatic measurements, such as precipitation or temperature. However, with the limited availability of long‐term, in situ soil moisture data sets, it has not been feasible to perform a direct analysis of the relationships between soil moisture levels and coccidioidomycosis incidence on a larger temporal and spatial scale. Utilizing in situ soil moisture gauges throughout the southwest from the U.S. Climate Reference Network and a model with which to extend those estimates, this work connects periods of higher and lower soil moisture in Arizona and California between 2002 and 2014 to the reported incidence of coccidioidomycosis. The results indicate that in both states, coccidioidomycosis incidence is related to soil moisture levels from previous summers and falls. Stated differently, a higher number of coccidioidomycosis cases are likely to be reported if previous bands of months have been atypically wet or dry, depending on the location.

球孢子菌病（谷热）的发生与土壤水分状况有关。

球孢子菌病（也称为谷热）是由土壤传播的球孢菌（Coccidioides spp ）引起的。，在美国西南部的干旱地区。尽管有些人感染了这种真菌后仍然没有症状，但其他人却因此患上了呼吸道疾病。较不常见的是，当感染扩散到身体的其他区域时，可能会导致严重的疾病和死亡。先前的分析试图将球孢子菌病的发生率与广泛可用的气候测量方法（例如降水或温度）联系起来。但是，由于长期就地土壤水分数据集的可用性有限，因此无法在较大的时空范围上直接分析土壤水分水平与球孢子菌病发生率之间的关系。在美国西南部各地使用原位土壤湿度计 气候参考网络和一个可以扩展这些估计值的模型，这项工作将2002年至2014年期间亚利桑那州和加利福尼亚州土壤湿度较高和较低的时期与所报道的球孢菌病发病率联系起来。结果表明，在这两个州中，球孢子菌病的发病率均与以前夏季和秋季的土壤水分含量有关。换句话说，根据位置的不同，如果以前几个月的波段非典型地潮湿或干燥，很可能会报告更多的球虫病病例。
