The Illinois Department of Public Health is asking residents to stay vigilant against the rise of norovirus. In a Facebook post on Monday, department officials said the virus is making its rounds across the state.

Cook County Public Health officials report, as of the end of December, they have seen 57 cases of norovirus, characterized by vomiting and diarrhea, in suburban areas and elsewhere.

Health officials said Monday that a patient in Louisiana with a severe case of bird flu has died, the first reported human death from the disease in the U.S.

More should be done to control the spread of bird flu among animals to avoid more cases in humans, the World Organisation for Animal Health (WOAH) said on Wednesday, following the first death of a patient from the virus in the United States.
