State health officials say two men from eastern Montana have died after contracting West Nile virus.
The Department of Public Health and Human Services says a man in his 80s died in Treasure County, while a man in his 70s died in Yellowstone County. An obituary in The Billings Gazette said 79-year-old Clyde Stanhope of Billings died Sunday of West Nile virus.
State officials say 15 cases of West Nile have been reported since early this month, including the two deaths.
Most people exposed to the mosquito-transmitted virus experience no symptoms. Some develop a mild illness, while fewer than 1 in 150 may become severely infected with encephalitis or meningitis.
