Loss of taste, smell key COVID-19 symptoms -British scientists' study
https://news.trust.org/item/20200331222223-j5t3m

Using all the data collected, the research team developed a mathematical model to identify which combination of symptoms - ranging from loss of smell and taste, to fever, persistent cough, fatigue, diarrhoea, abdominal pain and loss of appetite -was most accurate in predicting COVID-19 infection.

"When combined with other symptoms, people with loss of smell and taste appear to be three times more likely to have contracted COVID-19 according to our data, and should therefore self-isolate for seven days to reduce the spread of the disease," said Tim Spector, a King's professor who led the study.
