First Human Case of West Nile Virus Becomes First Death in 2022

September 9, 2022

The Illinois Department of Public Health (IDPH) has confirmed the first human case and first human death of West Nile virus in Illinois for 2022, which occurred in Cook County.

So far this year, mosquito batches have tested positive for the virus in 30 counties and eight birds have tested positive in six counties. In 2021, IDPH reported 65 human cases and five deaths.

Although it is now September, the weather is still warm and mosquitos still pose a risk for spreading the virus. Remind patients to continue to take precautions to protect themselves from mosquitoes.

Access IDPH’s guidance for healthcare professionals and view the Department’s 2022 West Nile Virus Surveillance Data, which is updated weekly.
