Influenza is often diagnosed by symptoms, but other respiratory viruses can mimic similar flu-like symptoms. Accurate and precise diagnosis requires lab tests for the presence of an influenza virus.

What is Influenza-Like-Illness (ILI)?

Influenza-like-illness(ILI) is an acute respiratory illness with a fever of ≥ 38°C and a cough, starting within the last 10 days. Severe acute respiratory infection (SARI) is also included in these symptoms but require hospitalisation.

What are the symptoms of Influenza-Like-Illness (ILI)?

The symptoms for influenza-like-illness include:

  • High-grade fever above 38.0ºC
  • Cough
  • Headache
  • Chills
  • Sore throat
  • Nasal congestion
  • Muscle or body aches
  • Fatigue

Gastrointestinal symptoms such as nausea, vomiting and diarrhoea can occasionally accompany influenza, especially in children.

In most cases, the symptoms subside within 10 days. However, for some, the symptoms could worsen within 48 hours.

Who are at risk of ILI?

The following group of individuals are at risk of ILI:

  • Children
  • Elderly population
  • Pregnant women
  • People with underlying medical conditions such as diabetes and heart disease

What can I do to prevent ILI?

Here are a few preventive measures that you can take to prevent ILI. They are similar to the steps taken to prevent other respiratory infections.

  • Practice social distancing.
  • Use a face mask if in contact with anyone.
  • Avoid going out if you are unwell.
  • Wash and sanitise hands regularly.
  • Keep your surrounding environment clean.
  • Adopt a healthy and active lifestyle.

Should I get vaccinated against influenza?

Another measure that can aid in preventing the severity of ILI would be influenza vaccination.

Getting an influenza vaccine may not prevent you from contracting the disease but it can prevent severe complications of the disease.

Consult your doctor on the influenza vaccine that would be suitable for you.

What should I do if I suspect I have influenza?

If you are showing any influenza-like symptoms and you suspect that you have influenza infection, you should seek medical attention.

You would also need to quarantine yourself and stay home to avoid contact with other people.

Most people with influenza have mild symptoms and do not require hospitalisation or antiviral drugs. However, if your symptoms worsen, seek medical attention immediately.
