According to British scientists, three new symptoms should be added to the official list of Covid-19 signs to watch out for parents.
As children return to school, experts say diarrhea, abdominal pain and illness have been identified as coronavirus symptoms in children.
The three signs the NHS lists as indicators of coronavirus are fever, cough, and a list of taste or odor.
But scientists at the University of Belfast, Northern Ireland, argue that upset stomach is the main indicator of Covid-19 in children, even more so than coughing.
Dr. Tom Waterfield told it the BBC: “We find that diarrhea and vomiting is a symptom reported by some children, and I think it is worth adding to the list of known symptoms.”
In the Belfast trial, about 1,000 children – with an average age of 10 – were blood tested to determine if they had recently had the bug, of which 68 antibodies with fever were the most common in about a third, according to medRxiv figures.
Cough was also a common feature, although less than a fever, and loss of smell and taste occurred only six times – while about 50 percent of those who tested positive reported being asymptomatic.
13 children said they had diarrhea, vomiting and stomach pain.
None of the 68 subjects had become seriously ill or had to go to hospital.
By analyzing people with a fever, cough, and loss of sensation, Dr. Waterfield and his colleagues correctly detected 76 percent of children with the disease.
And after adding people with stomach problems, it went up to 97 percent.
Dr. Waterfield added, “This study shows that about half of children are asymptomatic when infected with SARS-CoV-2 and that current UK testing strategies will fail to diagnose most pediatric infections.”
An official from the Department of Health and Social Care said the symptoms are under constant review as it continues to understand the virus and urged those with the main symptoms to get tested.
