Take a look at these descriptions of mild, moderate and severe COVID-19. At the end, tell us which one best describes how you’re feeling now.
How it feels: You’ll have flu-like symptoms, which can include cough, mild fever, headache, muscle pain and tiredness. You won’t be short of breath in general. You shouldn’t have a high fever. Keep yourself hydrated and rest. More info...
How it feels: You’re more breathless and feel your heart beat faster when you move around. The cough is more noticeable. You’ll be coughing many times an hour and it’s probably making you tired. You may have symptoms of a fever like shivering and chills. More info...
How it feels: You’re going to feel very breathless (even when you’re resting), and might find it hard to finish sentences. Along with chest, stomach or back pain when you breathe, these can be signs you’ve developed pneumonia. You will not be eating and drinking normally. Other signs include a high fever. More info...
Warning: If you’re feeling increasingly breathless, can’t manage basic things like showering and eating, or if you can’t speak in whole sentences without taking extra breaths, call your local health service right away.
