Seasonal influenza outbreaks - awareness and notification

20 December 2016

As we are now heading into the flu season, we are writing to remind you to be alert for any potential flu (influenza) outbreaks in your school setting, as well as the need to report to your local health protection team as soon as you suspect an outbreak.

Outbreaks often initially present as a sudden or unexpected rise in absenteeism and therefore a high index of suspicion is required. Obtaining information, where possible, about the types of symptoms experienced by individuals can help the assessment of whether or not you have an outbreak.

The definition of a flu outbreak is:

  • Two or more cases of flu-like illness within 48 hours which occur in pupils and/or staff who are in close proximity to each other

Symptoms and signs of flu-like illness include:

  • Fever of 37.8˚C (which usually start suddenly and can last for 3-4 days)
  • Plus one or more of:
    • Dry cough
    • Headaches
    • Chills
    • General muscle aches and pains
    • Runny nose or congestion
    • Sneezing
    • Sore throat
    • Wheezing
    • Some children may also feel sick (nausea) or have diarrhoea

Flu-like symptoms are worse and last longer than the ordinary cold. The fever tends to decrease after the second day when a stuffy nose and a sore throat become more noticeable.

If you suspect your school may have a flu outbreak, then please telephone your local Health Protection team (details below) who will provide you with further advice and support.
