Zoonotic Disease


Seasonally during the summer and fall months, Grays Harbor County monitors local areas for mosquito activity.  Specialized traps are set to collect mosquitoes which are then speciated and sent to UC Davis for West Nile Virus testing.  Testing is only conducted on known vector species and no mosquito pools have tested positive for West Nile Virus in Grays Harbor County. 

If you would like to report significant mosquito activity please contact:
