Find out more about Influenza-Like-Illness (ILI) and its symptoms and what you can do to prevent it.

Influenza-Like-Illness (ILI) can occur throughout the year in Malaysia. ILI is similar to COVID-19 whereby it is spread through direct contact with respiratory droplets from coughing and sneezing.

Influenza-Like-Illness (ILI) symptoms

Symptoms include:

  • High-grade fever above 38ºC
  • Cough
  • Headache
  • Chills
  • Sore throat
  • Nasal congestion
  • Muscle aches
  • Fatigue

Gastrointestinal symptoms that occasionally accompany influenza, especially in children:

  • Nausea
  • Vomiting
  • Diarrhoea

ILI symptoms subside within 10 days in most cases. However, they could worsen within 48 hours for some people. Seek medical attention if the symptoms worsen.

Individuals 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

Prevention of ILI

Preventive measures for ILI are similar to the steps taken to prevent COVID-19 infections, such as:

  • 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

Vaccination against influenza

Getting yourself and your loved ones vaccinated against influenza is another measure that can help in preventing the severity of ILI.

Although getting an influenza vaccine may not prevent you from ILI infection, it can prevent severe complications of the disease. 

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

What to do if you suspect you have influenza

If you are showing any influenza-like symptoms and you suspect that you have influenza, 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.
