Flu season is here and there are some steps you can take while it roars on.  Stay away from people who are sick.  If you are out in public keep your hands away from your face until you can wash them.  If you are sick, stay home!  A report from the Montana Department of Public Health and Human Services said that 425 new cases of the flu were report at the end of the first week of January.  All but 3 counties have verified at least one case in influenza.  A total of 237 cases have been reported in Yellowstone County.  According to the Centers for Disease Control and Prevention, this year's immunization is about 30 percent effective.
