An Oxford-Made Algorithm Will Calculate Your Personal COVID-19 Risk

Posted on 13 November 2020

Oxford researchers have developed an algorithm, QCovid, that will calculate an individual’s risk of catching and dying from COVID-19 during a 90 day period.

The algorithm takes into account a variety of factors that contribute to COVID-19 mortality such as age, body mass index and medical history. It was derived and validated using COVID-19 test result and death registry data from 1205 general practices in England. 

The creators warn that the QCovid risk calculator is not intended for use in supporting or informing clinical decision making. Calculations are made based on data from the early stages of the pandemic, and will change as new data becomes available.

It’s also important to remember that even if your risk of dying from COVID-19 is very low, that doesn’t necessarily mean you won’t suffer very unpleasant symptoms with lasting health consequences, and you can still transmit the virus to those who are at significant risk.
