The case of a 10-year-old boy who was diagnosed with the Wuhan coronavirus even though he showed no symptoms is raising concern that people may be spreading the virus undetected by the front-line screening methods implemented to contain the epidemic.
The boy was part of a family who visited relatives in the central Chinese city over the New Year. While his parents and grandparents fell ill and were treated after they returned to their hometown, the 10-year-old appeared healthy and was only diagnosed with the virus after his parents insisted he too was tested, his doctors said, adding that he "was shedding virus without symptoms."
