In late March, ZOE, a research team from the UK and the US, launched a COVID-19 symptom-tracking app for Android and iOS platforms. Preliminary results from the UK region show that 9 per cent of users in each region may have been infected with the new coronavirus.
The study, which found that 6.2 per cent of 14,124 app users in Birmingham, the UK’s second-largest city, had COVID-19 symptoms. It is unclear whether this proportion can be applied to Birmingham, a city of 1.1 million residents, and the actual number of new crown patients may need to be adjusted.
The researchers behind the app told CNN a few days ago that it was like a radar. In data released on April 1, researchers revealed that 59 percent of those who tested positive for the coronavirus said they had lost their sense of smell or taste, making it a very good indicator of whether you have the disease.
Lead researcher Professor Tim Spector, from King’s College London, commented
All we share today is the preliminary results from 2 million people who follow their symptoms every day.
With so many people across the country potentially contagious, we have to rethink our policy of testing everyone and come up with other ways to quickly understand the state of every part of our country.
Obviously, the level sparing lying across the country is very different. We would like to thank everyone who has been involved and call on everyone else to download this APP, whether you have any symptoms or good condition, to be tested every day.
Over time and with more user downloads, the results that researchers can use will become more accurate, potentially opening up new ways to stop transmission and ultimately help ingres normal. It is expected that researchers will release similar data from the United States in the coming days and weeks.
