New York - The CIA is investigating whether a recent outbreak of West Nile-like fever in New York might have been an attempt at bio-terrorism, the New Yorker magazine reported yesterday.
The virus, which killed five people and made at least 27 others ill, is believed to have been passed to people via mosquitoes that bit infected birds.
The magazine describes CIA analysts as having a "whiff of concern" that it might have been sent deliberately to the US.
