These first cases of West Nile virus are earlier than those of the first reported cases in 2017.
In 2017, the CDC reported 47 states confirmed 2,002 cases of West Nile.
Last year, eight people in Eastern Washington contracted West Nile from mosquitos, and five Washington residents were infected outside the state.
The California Department of Public Health West Nile Virus Program notified the County of Santa Cruz on Thursday of this summer's first find of a WNV-positive dead bird in the county. Symptoms may last from a few days to a few weeks.
No vaccine or specific antiviral treatment for West Nile virus exists, and people with weak immune systems, health conditions, and people older than 60 could be at higher risk for severe illness if they contract the virus, according to the U.S. Centers for Disease Control and Prevention. In rare cases, severe illness including meningitis or encephalitis, or even death, can occur.
REDUCE - make sure doors and windows have tight-fitting screens. Fix or replace screens that have tears or holes.
The public is asked to protect themselves from mosquito bites and to drain any standing water around their homes and report mosquito biting and standing water or green swimming pools in their neighborhood. Consult a physician before using repellents on infants.
"We can't stress the draining of standing water enough", he said. The local health department or city government may be able to add larvicide to the water, which will kill any mosquito eggs.
A resident submitted the dead American Crow to health officials on June 13 after finding it near 30th Avenue between Moran Lake and Pleasure Point, officials said.
Heavy rain tends to disrupt mosquito breeding spots, and warmer temperatures tend to speed up both the life cycle of mosquitoes and the replication of West Nile virus, Blackford said.
