WDH: Season's first case of West Nile reported in state

Jul 14, 2015 From staff reports

The season's first case of West Nile virus in Wyoming has been detected in Sheridan County.

"We want to remind residents to take steps to protect themselves and their families from mosquito bites," said Katie Bryan, WDH epidemiologist.

Mosquitoes spread West Nile virus when they feed on infected birds and then bite people, animals and other birds.

Bryan said at least two states surrounding Wyoming also have had confirmed West Nile virus cases so far this season.

In Wyoming last year, five human West Nile virus cases were reported. Since West Nile virus first appeared in Wyoming in 2002, reported human cases within a year have ranged from two with no deaths to 393 and nine deaths.

Most people infected with West Nile virus don't have symptoms. Among those who become ill, symptoms include fever, headache, body aches, skin rash and swollen lymph nodes.

A small number develop West Nile neuroinvasive disease with symptoms such as severe headache, fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions and paralysis.
