Prevention of West Nile Virus
Community-level mosquito control programs Personal protective measures to avoid mosquito bites No West Nile virus vaccines are licensed for use in humans. Personal protective measures to decrease exposure to infected mosquitoes, includingdiethyltoluamide(DEET), mosquito netting, and protective attire, should be used. Blood and some organ donors are screened for West Nile virus by nucleic acid–based tests. Healthcare professionals should remain vigilant for the possible transmission of West Nile virus through blood transfusion or organ transplantation. There is no evidence that humans acquire West Nile virus infection from handling dead or infected birds, but the CDC still recommends wearing gloves when handling dead birds (or any animal).
