This unseasonably warm winter we've been having has been nice, but doctors say it could be leading to a huge influx in very sick kids in the Chippewa Valley. Pediatricians at Mayo Clinic Health System say the past few weeks they've seen a spike in upper respiratory illnesses like RSV and pneumonia, and they theorize it's the mild weather that may be at fault…“There’s been a real explosion in the area with really sick kids with respiratory problems, primarily RSV, we've also had pneumonia,” pediatrician Dr. John Plewa says.
