Small bumps on tongue could be latest coronavirus symptom, doctors warn

Small bumps on the tongue have been identified as a potential new symptom of coronavirus in a study which looked at hundreds of patients.

Researchers, who examined the Covid-19 carriers in a temporary field hospital in Madrid, Spain, found a quarter had a rash in the mouth.

The most common form was transient lingual papillitis which shows itself as small red or white bumps on the tongue.

Doctors often examine the mouth as a way to determine the overall health of a patient as it can give strong indicators of their current wellbeing state.

The study looked at patients who had a mean age of 56, with 58% of them female.

Research by King’s College London and the British Association of Dermatologists study has also linked skin rashes to coronavirus.

Veronique Bataille, consultant dermatologist, who led the Covid skin study, said: “Our research shows that rashes can be more predictive of Covid-19 than fever and cough, particularly in children.

“We found that one in six children gets a rash without any other classical symptoms. For most, Covid-19 rashes last for a few weeks and eventually disappear. In some cases, prescribed medication may be needed if the rash is very itchy.”

Images were collected via the Covid Symptom Study app, which was launched in March to help scientists gather information about the symptoms of Covid-19.

They showed that eight types of rash could be signs of Covid-19, including red toes and fingers, chest eczema and pityriasis rosea.

The app also revealed that around 9% of coronavirus patients reported a body rash or a rash on their fingers or toes, and rashes were twice as common in children.

Rashes can appear before, during or after other symptoms, and sometimes weeks later.

Dr Tanya Bleiker, President of the British Association of Dermatologists, said: “The association between certain rashes and Covid-19 has become increasingly clear, and being able to recognise these is crucial for reducing the spread of the disease.”
