Researchers examined patients at a temporary field hospital that had been set up at the peak of the pandemic in Madrid, Spain.
They analysed 666 coronavirus patients with mild to moderate pneumonia.
The mean age of the patients was 56 and 58 per cent of them were female.
Experts revealed that 46 per cent of patients had some form of mucocutaneous manifestation (immune deficiency syndrome), with the hands and feet being particularly affected.
They also found that 26 per cent of patients had a rash inside the mouth and the most common in the mouth was transient lingual papillitis.
This is also known as lie bumps and is small red or white bumps on the tongue.
The experts added that skin rashes were “relatively uncommon” with just 11 per cent of participants experiencing this.
It comes after experts at King’s College London said skin rashes should be considered as the fourth official coronavirus symptom.
At present the NHS lists a new persistent cough, a lost of taste and smell or a high temperature as the key symptoms.
Researchers said they identified eight different types of skin rash which could be a potential sign of Covid-19.
The experts from King’s College London, who run the Covid Symptom Tracker app, noticed a rise in users reporting the unusual reaction.
They found that nine per cent of people who had tested positive for coronavirus also had either a body rash or a rash on their fingers or toes.
Researchers said rashes were twice as common in children as in adults and may be a better predictor of having a swab test than a fever or cough.
According to the data, rashes may appear before, during or after the presence of other Covid symptoms and sometimes many weeks later.
Rashes were also the only sign of infection for 21 per cent of people with a positive nasal swab.
In July doctors also warned that a rash in the mouth could be a sign of the virus
Experts in Spain examined the mouths of 21 coronavirus patients who had rashes on their skin to see if they had enanthem (oral cavity lesions) or a rash inside the body on the mucous membrane.
The mucous membrane lines many tracts in the body and is found in the mouth, nose, eyelids and lungs.
Coronavirus patients at Roman y Cajal University Hospital in Madrid, Spain were given dermatology appointments between March 30 and April 8.
Researchers found that 29 percent of the patients had some form of enanthem in their mouths.
