Official state bird is ‘super spreader’ of West Nile virus, researcher says

The official state bird of Wisconsin is being called the primary culprit in spreading a deadly virus across the Northeast and Midwest. The American robin is being called the West Nile “super spreader,” based on research conducted by a team headed by UW-Madison infectious disease expert Tony Goldberg. “Robins are in the sweet spot,” Goldberg said in a news release from UW-Madison. “They are abundant, mosquitoes like to feed on them and they happen to support virus infection better than other species.”
