The fifth duplicate the symptoms of the previous one, adding confusion, loss of appetite, sore throat, and muscle pain.

In the fourth cluster, the scientists said patients reported loss of smell, cough, headache, fever, hoarseness, chest pain, and fatigue.

And the team behind the study said that while some of the listed symptoms - such as confusion, abdominal pain and shortness of breath - had not been widely linked to COVID-19, they were hallmarks of its most severe forms.

The King's College finding provides insight into six distinctive types of COVID-19, as well as the severity each could achieve depending on the course of the disease in infected patients and thus help the health care team consider who will be more serious.

Experts said the findings could have important implications for identifying and treating those who are more vulnerable and will suffer from a severe type of Covid ahead of a possible second wave. "This approach is helping us to understand the unfolding story of this disease in each patient so they can get the best care".

Apart from fever, cough, and loss of smell - which are known as the key symptoms of novel Coronavirus infection - the app data, analyzed by the scientists, has revealed other symptoms such as headaches, diarrhea, muscle pains, loss of appetite, fatigue, confusion, and breathing difficulties.

The Centers for Disease Control and Prevention in Atlanta has released a report narrowing to three, the most likely symptoms for people who have the coronavirus.

"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 COVID-19 required breathing support". For clusters 4, 5, and 6, the researchers said these figures were 8.6, 9.9, and 19.8 per cent respectively. However, it was not recognised as a symptom during the time when the data was gathered for this analysis so it is now unknown how skin rashes map on to these six clusters.

"This may be more acceptable to the residents and will help reduce the burden on existing facilities for managing suspect / pre-symptomatic / asymptomatic / very mild cases of COVID-19", it said.

Broadly, people with cluster 4,5 or 6 COVID-19 symptoms 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.

Almost half of the patients in cluster six, according to the study, ended up in hospital, compared with just 16 per cent of those in cluster one.

Three "severe" clusters were identified. Shortness of breath was more typically associated with individuals who were hospitalized. "These respiratory symptoms were combined with significant abdominal pain, diarrhoea and confusion when compared with other clusters", according to the study.
