According to the Department of Public Health and Environment, the Mead resident became ill on July 27 and was hospitalized the next day. Tests confirmed that the person had the neuro-invasive form of the virus.
It's the first human case of the virus in Colorado for the 2018 mosquito season.
Most people who are bitten by an infected mosquito either have no symptoms or have temporary, flu-like symptoms while others contract a much more severe illness.
"Luckily, the summer to this point hasn't been extremely wet, which has limited prime breeding conditions for mosquitoes", Callanan said.
"If there is a four-fold increase in the antibody count in the second sample, only then can we say it is a West Nile infection". It's infected more than 150 people in the state over the past six years. According to the Centers for Disease Control and Prevention, most people infected with the virus may not show any symptoms but some may experience fever along with body aches, joint pain, headaches, vomiting and diarrhoea.
There are no medications to treat or vaccines to prevent infection.
Things like bird baths should be changed at least weekly. Do not forget to drain water from tires, cans, flowerpots, clogged rain gutters, rain barrels, toys and puddles.
Avoid the outdoors from dusk until dawn.
"Public Health thanks the community for being diligent in removing standing water and eliminating the places where mosquitoes can breed", Callanan said.
