Since youngsters under 19 often have no or very mild coronavirus symptoms, many of them may be silent spreaders of the disease, a study warns.
The study led by Prof. Han Mi-seon at Boramae Medical Center analyzed 91 patients under 19 from Feb. 18 to March 31.
It found that 57 of them only had mild symptoms that did not require treatment and 20 had none at all.
Yet they were contagious for an average of 17.6 days, suggesting there is a higher risk of asymptomatic youngsters spreading the virus.
"Young patents seem to be contagious for longer than adults," Han said. "Thorough testing of youngsters is needed to prevent community infections."
