London. The loss of the senses of smell and taste could be the best way to determine if someone has Covid-19, according to a study of data collected via a tracking application of symptoms developed by british scientists to help monitor the pandemic caused by a coronavirus.
Almost 60% of the patients who tested positive for Covid-19 reported to have lost the senses of smell and taste, according to data analyzed by the researchers. This compares with 18% of those who tested negative.
These results, which were published on the internet but have not been peer-reviewed, had a lot more strength to predict a positive diagnosis by Covid-19 that the report of fever, said researchers from King’s College London.
Of the 1.5 million users of the app between the 24th and the 29th of march, 26% reported one or more symptoms through the device. Of those, a thousand 702 said they had been subjected to the test of the Covid-19, 579 positive, and a thousand 123 negative.
Using all the data collected, the team developed a mathematical model to identify what combination of symptoms -from loss of taste and smell, fever, persistent cough, fatigue, diarrhea, abdominal pain, and loss of appetite – it is more accurate to predict the infection Covid-19.
“When combined with other symptoms, people with loss of smell and taste seems to be three times more likely to have contracted the Covid-19 according to our data and, therefore, should autoaislarse for seven days to reduce the spread of the disease,” said Tim Spector, a professor at King’s who led the study.
The team of Spector applied his findings to the more than 400 thousand people reported symptoms by the ppp and had not yet been made the test of the Covid-19, and found that almost 13% of them were probably infected.
This would imply that about 50 thousand people in the Uk could be infected by the Covid-19 without being confirmed, said Spector.
The official figures showed that the confirmed cases were up 14% in the Uk between Monday and Tuesday, and up to 25 thousand 150 Tuesday 08 hours GMT. The government said that it had died a thousand 789 people by coronavirus in hospitals at 16 hours GMT on the Monday.
