Deadly mosquito-borne virus claims first life in major US city as cases spread

A Chicago resident has died from West Nile virus, marking the city’s first death linked to the mosquito-borne illness this year, according to the Chicago Department of Public Health.

Several other cases have been reported throughout Illinois.

The virus is most commonly spread to people through the bite of an infected mosquito, although the disease cycle also includes infected birds. When mosquitoes feed on infected birds, they can pick up the virus and transmit it to humans.
