Losing your sense of smell and style may be one of the best ways to tell if someone has COVID-19, according to a study of data collected through a symptom tracker app built by British scientists to help monitor the pandemic brought on by the new coronavirus.
Nearly 60% of sufferers who had been subsequently shoed as positive for COVID-19 had reported losing their sense of taste and smell, the data analyzed by the researchers showed.
These outcomes, which had been posted online; however, it not peer-reviewed, have been much stronger in finding a positive COVID-19 diagnosis than self-reported fever, the researchers at King’s College London stated.
Of 1.5 million application users between March 24 and March 29, 26% posted one or more symptoms via the app. Of these, 1,702 also reported having been diagnosed with COVID-19, with 579 positive outcomes and 1,123 negative outcomes.
Using all the data gathered, the analysis team built a mathematical model to establish which combination of symptoms – starting from lack of smell and taste to fever, persistent cough, fatigue, diarrhea, stomach pain and lack of appetite -was most accurate in predicting COVID-19 infection.
Spector’s staff utilized their findings to over 400,000 people reporting symptoms through the app who had not yet had the coronavirus test, and located that nearly 13% of them are likely to be infected.
This is able to suggest that around 50,000 individuals in Britain may have as yet unconfirmed COVID-19 cases, Spector stated.
