Impact

SpreadNotesScore
Spread RateThe disease does not spread readily without a vector. Humans do not shed WNV in secretions or excretions, but the virus can be transmitted by blood transfusions and in organ transplants.4
Spread AmountAll of California can be affected. However, it is unlikely that it will have too significant an impact on agriculture (chickens and turkeys seroconvert but remain asymptomatic).3
DamageNotesScore
EcologicalCan be potentially harmful to wild bird communities.3
AgriculturalSignificant impacts on chicken, egg, and turkey flock production if infected birds discovered as flocks subject to destruction.4

Health0% of infected humans remain asymptomatic; 20% have flu-like symptoms. Less than 1% develop meningitis, encephalitis or acute paralysis, but some of these cases are fatal or result in permanent impairment.3

Ability to Respond

Ease of ResponseNotesScore
DetectionAn easy serological test will detect it.4
ControlThere is no treatment other than supportive care for humans. There is truly no way to control it in animal populations1
Tools in PlaceNotesScore
EntryBecause it is transmitted through mosquitoes, it is impossible to keep out of a state.0
ControlYou are mandated to report a WNV finding within 2 days of detection.4
OutreachThere is an abundance of educational resources.5
