All schools in the Millburn School District were open on Monday following cleaning over the weekend, but absences remained high at the middle school.

Millburn Middle School was closed on Friday to be cleaned following a spike in absences, which were at 170 on Thursday. The average is 40. School officials also confirmed two cases of H1N1, commonly known as the swine flu.

Nancy Dries, school public information officer, said there were 176 students absent at the middle school Monday, which was up by six from Thursday's figure. The elementary schools were "holding their own," and the high school is in the middle of exams while seniors are not attending school, she said.

While Millburn Middle School was closed on Friday for cleaning, all schools were cleaned over the weekend. All desks were washed and floors were bleached as part of the process.

Schools Supt. Richard Brodow is expected to give an update during Monday's school board meeting. The board meets at 7:45 p.m. at the Education Center.

Also on Monday, state health officials reported the first death linked to H1N1 in New Jersey, according to a Star Ledger report. A 49-year-old Essex County man died due to complications connected to the disease at Mountainside Hospital in Montclair, according to the article.
