Flu Season School Newsletter: What to Send and When to Send It

Flu season is the most predictable health challenge in the school calendar. It arrives every year, it follows a similar arc, and the communication responses that worked last year will work this year. The school nurses who handle flu season well are the ones who communicate early, stay specific, and give families clear guidance before the situation becomes urgent.

Send your first flu newsletter before the season starts

Late October is the right time for your first flu communication of the year. Most flu seasons in the US peak between December and February, but early October cases are common in school settings where students are in close contact all day. A late October newsletter gives families two to three weeks of preparation time before the peak arrives.

This first newsletter should be informational rather than alarming. Cover what flu is, how it spreads in school settings, and what families can do right now to reduce risk. Handwashing, covering coughs, and keeping symptomatic children home are the three most effective things families can control.

Be specific about symptoms and the stay-home threshold

Families cannot make good decisions without clear criteria. Tell them exactly what symptoms require a child to stay home. Fever over 100.4 degrees, body aches, sudden fatigue, and persistent cough are the most important ones to name explicitly. Avoid vague language like "if your child seems unwell." Parents need a specific threshold they can apply at 7am when they are deciding whether to send their child to school.

Explain the return-to-school standard for flu

Flu has a specific return-to-school consideration that differs from some other illnesses. CDC guidance recommends staying home for at least 24 hours after fever resolves without fever-reducing medication. Many families do not know this distinction. State it clearly in your newsletter and explain why: students who return while still contagious spread the virus to classmates even if they feel better because of medication.

Cover what happens during a building outbreak

If you have seen a significant increase in flu-related absences, communicate that directly. Families want to know when something is circulating, and they take prevention guidance more seriously when they know it is an active situation. Share the number of health office visits if that is appropriate for your context, and outline the specific steps the school is taking: increased surface disinfection, health office monitoring, and outreach to families of students with chronic conditions.

Address antiviral medication briefly

Some families do not know that antiviral medications for flu are most effective when taken within 48 hours of symptom onset. A brief mention that a doctor visit early in illness may result in treatment options is useful for families whose children tend to have severe flu symptoms. You are not prescribing. You are giving families information they can act on.

Close with your contact information and the health office hours

Families with a sick child at 6:30am need to know they can call the health office before the school day starts, or that there is a process for reaching you. Close every flu season newsletter with your phone number and the best window to reach you for morning illness questions. That one detail reduces the number of sick children who arrive because their family did not know who to call.
