From: Transmission risk of Oropouche fever across the Americas
Enhanced vegetation index (EVI) values across Oropouche virus (OROV) transmission risk map. Vegetation difference between 2019 and 2003 from the MOD13A2 version six products from the MODIS sensor from the TERRA satellite. A Regions with low (green) and high (brown) EVI difference are depicted inside the OROV transmission risk map. B Results of a randomization test using the mean of EVI values from the 35 OROV occurrences (red line) in comparison with 1000 replicates of 35 random draws across the OROV transmission risk map. Note that observations (arrow) fall outside the non-significant region (dashed lines) C Same as B but using the median as observed statistic.
