As September is one of the months when most human cases of West Nile virus have been reported in Delta County and in Colorado, the public is encouraged to take preventative measures against the virus, particularly when outdoors. The following West Nile Virus 4D prevention tips are encouraged: 

  •  Drain standing water on property.  
  • Dusk and Dawn- avoid being outdoors at this time when mosquito activity is high. 
  •  DEET, picaridin, and oil of lemon eucalyptus are effective ingredients in bug repellent. 
  • Dress in long sleeves and pants during dusk and dawn and in areas where mosquitoes are active and open windows tightly screened.
