Clarification: Big Lake School Nurse Nadynne Dziura wrote in about last week’s article on influenza. “When the public schools report to the Minnesota Health Dept. because we have five percent or more of our students out at the same time with influenza like illness--cough, sore throat, fever, headaches, body aches and fatigue--the report is because we have an outbreak. We would not define an outbreak as an epidemic,” she says. Epidemiologists at the Minnesota Dept. of Health, who monitor the state and use their critical analysis to confirm data, make the evaluations which go into calling larger outbreaks an epidemic if they meet the criteria, Dziura says.
