An inmate at Rikers Island in New York City is ill with swine flu.

City Correction Department spokesman Stephen Morello says the inmate complained of a cough and fever on Wednesday and went to a Queens hospital. He was confirmed to have swine flu on Friday. Morello says his condition is not serious.

Morello says the inmate entered the jail about a month ago. He did not know why he was in custody. Correction officials examined about 70 other prisoners the inmate had come into contact with during his stay and none have the flu.

An assistant principal in Queens remains hospitalized in critical condition after he was confirmed to have swine flu. Mitchell Wiener went to one of six schools closed this week in the latest outbreak in the city.
