Daniel Pastula, chief of neuroinfectious diseases and global neurology at the University of Colorado School of Medicine and the Colorado School of Public Health, says the state is watching troubling signs as well. “The concern this year,” Pastula said, “particularly along the Front Range in Colorado, is we’ve found many more mosquitoes [that are] positive for West Nile earlier in the season compared with other years.”
