The above ☝️ study from Slovakia had to contend with three different geographically co-circulating flaviviruses: West Nile Virus, Usutu Virus, and Tick-Borne Encephalitis #Virus.
For comparison, here's a study from the Amazon, looking at cross-reactivity among three different #flavivirus: Dengue Virus, Yellow Fever Virus, and Zika Virus.
