Flu or Flu-like illness in chronically ill or disabled children

What is flu or flu-like illness?

Flu-like illness is a non-specific collection of symptoms, including cough, fever, and muscle aches, which is often caused by infection with the influenza or other viruses. 

We therefore often refer to people as having a ‘flu-like illness’ rather than just ‘flu’ because it is difficult to say exactly which virus is causing their symptoms.

We asked Dr Kay Wang a GP and researcher with a specialist interest in flu and other viruses to help explain what a ‘Flu-like illness’ is, and to clear up some misunderstandings about the condition.
