Influenza Preparedness 2018-2019
Case Definition of Influenza Like Illness (ILI)
Sudden onset of symptoms
And
At least one of the following four systemic symptoms:
• Fever or feverishness
• Malaise
• Headache
• Myalgia (muscle pains)
And
At least one of the following three respiratory symptoms:
• Cough
• Sore throat
• Shortness of breath
Influenza Preparedness 2018-2019
Influenza in the Elderly
• In older adults, symptoms may initially be very subtle and
difficult to recognise. Elderly residents may present only
with
– cough, fatigue and confusion.
– fever response may be more blunted.
– Influenza may present in the elderly patient as an exacerbation
of an underlying condition
• If an increased number of residents become unwell over
a short period of time with respiratory illness, influenza
should be suspected.
Influenza Preparedness 2018-2019
Three or more cases (amongst residents and/or staff) of
influenza like illness (ILI) or influenza or respiratory illness
• within the same 72 hour period in the RCF,
• which meet the same clinical case definition and
• where an epidemiological link can be established.
