New York State Health officials say a second outbreak of influenza is landing more people in the hospital in the first week of April than in January.

Officials say most cases of the flu at the start of the season were recorded as the Influenza A virus, H1N1 while most of the cases in the second wave are Influenza B.

Even people who have had the flu already this season can get it again, especially if they have not been vaccinated.

2,500 cases of flu were reported in the first week of April, resulting in the admission of 648 New Yorkers to the hospital.

Health officials are continuing to advise people to get flu shots if they have not done so this season.
