The death of a North Bergen kindergartner over the weekend may have been flu-related, officials said Monday.

The superintendent of North Bergen Schools confirmed the death occurred over the weekend. A cause of death has not been released, but the school did allude to the possibility of complications from the flu.

"Today is a sad day in the North Bergen School District as we have lost one of our own. I would like to express on behalf of the entire North Bergen School District, our deepest sympathies for the family of the student, our hearts, thoughts and prayers are with you during this difficult time," Superintendent Dr. George Solter said in a statement.

Solter added that Lincoln School, the elementary school that the student attended, has been disinfected with bleach.

New Jersey health officials have called this one of the worst flu seasons that they have ever seen, with thousands of confirmed cases statewide.

A 4-year-old girl from central New Jersey died in January from flu complications.
