The first likely case of human West Nile infection in 2004 was reported in Ohio on Tuesday, health officials said. The Ohio Department of Health said a 79-year-old man was believed to be infected with the virus, which first appeared in the United States in 1999 and which has spread coast to coast and to Canada and Mexico. “Today’s development should remind us all of the importance of taking personal protection measures and working to eliminate mosquito breeding sites on and around our properties,” Dr. Nick Baird of the Ohio Department of Health said in a statement.
