London – Researchers have now indicated that tracking symptoms affiliated with the novel coronavirus (COVID-19) through an app may not be a good predictor of the spread of the disease. Over the course of 2020, as the COVID-19 has spread across the globe causing extensive illness and economic havoc to communities everywhere, health care providers and the general public have been eager to find a way to identify the illness. In the Family Practice study, general practitioners referred to most patients because they were complaining of COVID-like symptoms. “Indeed, nearly half the patients in the sample reported fever (45.4 per cent), reflecting the common reason for doctors to refer patients to testing at the time these data were collected,” the authors wrote. Fever was registered in the app in the Nature Medicine study by only one-third of patients.
