A lesser known COVID-19 symptom to look out for

While fever, tiredness and a dry cough are the most common symptoms associated with COVID-19, the respiratory illness caused by the new SARS-CoV-2 coronavirus, evidence is beginning to show that a sudden loss of smell or taste could also be a sign.


The latest researchers to report that a loss of smell and taste could be associated with COVID-19 are a team from King’s College London. They looked at responses from more than 400,000 people with suspected COVID-19 symptoms who entered how they were feeling into an app.


Of the people who had tested positive for COVID-19 (579 individuals), three-fifths (59%) reported a loss of smell or taste.


While a loss of smell or taste have not yet been added to the official list of COVID-19 symptoms published by the NHS or Public Health England, it is important to note that the current situation is rapidly evolving and this could change at any time.


The King’s College researchers say that a loss of smell or taste should not be used on their own, but could be useful when considered alongside other important symptoms such as a dry cough and fever.


Speaking about their findings, lead researcher Professor Tim Spector said: “When combined with other symptoms, people with loss of smell and taste appear to be three times more likely to have contracted Covid-19 according to our data, and should therefore self-isolate for seven days to reduce the spread of the disease.”
