Traditional Outdoor Activities for the 4th of July Weekend Are Cause
to Remember Precautions
This 4th of July weekend, while out enjoying the holiday, Boulder
County Public Health officials would like to remind residents that West
Nile virus (WNV) is still a very real threat, and they should take
action to protect themselves. The recent wet weather, followed by hot
temperatures has created the right conditions for mosquito breeding.
Boulder County is seeing a rise in the Culex mosquito population, which
is known to carry and transmit the virus.
Boulder County has reported no human cases, and no positive horses,
mosquito pools, or birds. Statewide, Colorado has reported the first two
human cases of the year; a 50 year-old female from Weld County and a 17
year-old male from Ft. Collins. Additionally only 1 positive bird and no
positive mosquito pools or horse cases have been reported.
Across the U.S, one human death has been reported from Missouri and two
other human cases have has been reported from Kansas and California.
California and Arizona are the most active states with numerous counties
reporting positive birds, sentinel chickens and mosquito pools.
