First Human West Nile Virus Case This Year Found in Delta County

The Delta County Department of Health is reporting the first human case of West Nile virus. This case is a resident from the North Fork region of the county.  The first case is a female diagnosed August 9th and is recovering from West Nile Virus febrile illness.

“West Nile Virus can be a serious illness and residents should understand the health risks associated with this virus" said Delta County Environmental Health Director Ken Nordstrom. "August through September are when most human cases of West Nile virus have been reported in Colorado."

Health officials say most people bitten by a West Nile virus infected mosquito show no symptoms of illness; however, some people may develop symptoms 3 to 15 days after being bit by an infected mosquito. About 1-in-5 infected persons will have mild illness with fever, and about 1-in-150 infected people will become severely ill. Physicians are urged to test patients for the West Nile virus in the summer months if they show signs of fever, altered mental status, suspected meningitis or encephalitis, or sudden painless paralysis in the absence of stroke.


The public is encouraged to take preventative measures against the virus. The following prevention tips are encouraged:

  • Drain standing water on property.
  • Dusk and Dawn- avoid being outdoors at this time when mosquito activity is high.
  • DEET is an effective ingredient to look for in bug repellent.
  • Dress in long sleeves and pants during dusk and dawn and in areas where mosquitoes are active, and open windows should be tightly screened.
