A new study of COVID-19 determined that there are six distinct “types” of the disease involving different clusters of symptoms.
This is study is based on data from a symptom tracker app
The discovery could potentially open new possibilities for how doctors can better treat individual patients and predict what level of hospital care they would need.
Researchers from King’s College London studied data from approximately 1,600 U.K. and U.S. patients who regularly logged their symptoms in the COVID Symptom Tracker App in March and April.
The study, which has not been peer-reviewed, says the six different “types” of COVID-19 can vary by severity and come with their own set of symptoms.
Bob Lahita, who is not affiliated with the study, told CBSN that “Among the patients I see, those who recovered, many of them present different ways: some people with fever and some without fever, and some with nausea and vomiting, some people with diarrhoea, etc.”
The six clusters of symptoms outlined in the study are:
- 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.
The U.K. researchers also found that only 16% of patients with type one COVID-19 required hospitalization, compared with nearly half of the patients with type six.
