  • Sore throat
  • Nasal congestion

  • 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 COVID-19 infections.

  • Practice social distancing
  • Use a face mask if in contact with anyone
  • Avoid going out if you are unwell

Should I get vaccinated against influenza?

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