The infected man, who is in his 40s, has recovered, according to
Cindy Parmenter, spokeswoman for the state's Department of Public
Health and Environment.
The virus has killed 71 people in the United States and infected
more than 14-hundred people in 30 states and the District of
Columbia. Colorado would become the 31st state.
Cases of the virus began showing up in horses and birds in
Colorado in August. Mosquitos spread the virus after drawing blood
from infected animals.
About 150 people in Colorado have been tested.
The virus is most dangerous for children, the elderly and people
with weak immune systems. It can cause flu-like symptoms and
encephalitis, a potentially fatal brain infection. Most people
bitten by an infected mosquito don't become ill.
