Scientists identify six strains of coronavirus

The data revealed people infected with COVID-19 reported additional symptoms on top of the previously recognised cough, fever, and loss of smell.

These symptoms can be grouped into six distinct clusters, according to a statement published by the COVID Symptom Study after the researchers analyzed the results.

The six clusters or types of COVID-19 are:

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

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

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

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

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

6. Severe level three, abdominal and respiratory

“These findings have important implications for care and monitoring of people who are most vulnerable to severe COVID-19,” Dr. Claire Steves, a consultant geriatrician and a member of the team working on the study said.
