As researchers fight to stop the spread of a novel coronavirus that originated in a seafood market in the central Chinese city of Wuhan, they are facing a counter-intuitive problem: the symptoms can sometimes be so mild in patients that the virus is very difficult to detect. The coronavirus initially came to authorities' attention in December after patients began exhibiting symptoms of viral pneumonia, including fever, cough and shortness of breath. But researchers, including those at the U.S. Centers for Disease Control and Prevention (CDC), have noted that some of those with the Wuhan coronavirus have shown “little to no symptoms.” A study published in the medical journal the Lancet on Jan. 24 reported that a 10-year-old who was infected with the virus had no symptoms at all. “We have seen patients, especially children, who have pneumonia, but have no symptoms, no fever or cough, which means that it’s not easy to recognize these cases of novel coronavirus infection, which makes the control of this outbreak more difficult,” says Yuen Kwok-yung, a microbiologist at the University of Hong Kong, and one of the authors of the Lancet study.
