State health officials are confirming Ohio's second human case of West Nile virus this year. A 48-year-old Cuayhoga County man is hospitalized with inflammation of the brain. The first case was confirmed last week in Clermont County involving an 85-year-old man who remains hospitalized. The state says more than 445 mosquito pools have tested positive for the virus so far this year, an increase from nearly sixty at this point last year. Ohio has recorded human cases of the virus each year since 2002. There were 21 cases last year.
