LONDON (Reuters) - "Losing your sense of smell and taste may be the best way to tell if you have COVID-19, according to a study of data collected via a symptom tracker app developed by scientists in Britain and the United States to help monitor the coronavirus pandemic.
Almost 60% of patients who were subsequently confirmed as positive for COVID-19 had reported losing their sense of smell and taste, data analysed by the researchers showed. That compared with 18% of those who tested negative. These results, which were posted online but not peer-reviewed, were much stronger in predicting a positive COVID-19 diagnosis than self-reported fever, researchers at King's College London said."
