Scientists have identified six distinct types of COVID-19 - each with a specific collection of symptoms - in a breakthrough that could help doctors predict which patients are most at risk.

They presented the six distinct clusters - or "types" of COVID-19 - as follows:

1. 'Flu-like' with no fever - Headache, loss of smell, muscle pains, cough, sore throat, chest pain, no fever.

2. 'Flu-like' with fever - Headache, loss of smell, cough, sore throat, hoarseness, fever, loss of appetite.

3. Gastrointestinal - Headache, loss of smell, loss of appetite, diarrhoea, sore throat, chest pain, no cough.

4. Severe level one, fatigue - Headache, loss of smell, cough, fever, hoarseness, chest pain, fatigue.

5. Severe level two, confusion - Headache, loss of smell, loss of appetite, cough, fever, hoarseness, sore throat, chest pain, fatigue, confusion, muscle pain.

6. Severe level three, abdominal and respiratory - Headache, loss of smell, loss of appetite, cough, fever, hoarseness, sore throat, chest pain, fatigue, confusion, muscle pain, shortness of breath, diarrhoea, abdominal pain.

It was discovered that only 1.5% of people with cluster 1, 4.4% of people with cluster 2 and 3.3% of people with cluster 3 required breathing support.

But these figures were 8.6%, 9.9% and 19.8% for clusters 4, 5 and 6 respectively - while nearly half of the patients in cluster 6 ended up in hospital, compared with just 16% of those in cluster 1.

The researchers said that, in general, people with clusters 4, 5 or 6 tended to be older and frailer, and were more likely to be overweight and have pre-existing conditions such as diabetes or lung disease than those with type 1, 2 or 3.

This allowed them to devise a model which they say predicts more accurately - and, crucially, earlier - which cluster each patient falls into and how likely they are to require hospital treatment and breathing support.
