COVID-19

Also called Coronavirus, SARS-CoV-2, or Covid

COVID-19 is an infection of the airways and lungs caused by the SARS-CoV-2 coronavirus. Most people have mild, cold or flu-like symptoms and recover within a few days to weeks. Older people and those with weakened immune systems or certain long-term conditions are more likely to become seriously ill.

What it is

Vaccination lowers the risk of serious illness. Antiviral treatments are available for some people at higher risk if started early.

Some people have symptoms that last for weeks or months after the infection, known as long COVID.

Common signs

  • High temperature or shivering
  • A new, continuous cough
  • Loss or change in sense of smell or taste
  • Shortness of breath
  • Tiredness, aches, headache, sore throat

How it is usually diagnosed

  • Lateral flow (rapid) test
  • PCR test

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Positive test results with dates
  • Vaccination records
  • Hospital discharge summaries, if admitted
  • Notes on any lasting symptoms

Questions to ask your doctor

  • Am I eligible for antiviral treatment?
  • When should I get my next vaccine?
  • What should I do if symptoms last more than a few weeks?

When to get help right away

Call 112 or go to the nearest emergency department if you have:
