Another Oklahoma school district is canceling or postponing classes and other activities because of a high incidence of influenza.

Porum Superintendent Rick Antle told the Muskogee Phoenix that his district will cancel classes for the rest of the week because of an increasing number of flu-related absences. Antle says 130 of the district's 500 students were absent Monday, and that number jumped to 196 on Tuesday.

He says teachers and bus drivers also have been affected.

Officials of the Thomas-Fay-Custer School District canceled classes on Friday after more than 100 of the 450 students were out the previous day.

Other districts that closed because of the flu last week were Binger-Oney, Dewar and Stroud.
