West Nile Virus Discovery

The discovery of West Nile virus was largely accidental, initially overlooked in favor of more prominent mosquito-borne diseases. It wasn't until the 1950s that significant outbreaks were recognized, particularly in Israel, where a staggering attack rate highlighted the virus's potential for widespread impact. Early research revealed that many infected individuals showed no symptoms, while the ecology of the virus was linked to various bird and mammal species, paving the way for a deeper understanding of its transmission.
