WUHAN (Caixin Global): New research based on data gathered from more than 1,000 coronavirus patients in China found that the incubation period for the virus was as long as 24 days rather than the previously believed 14 days, and fewer than half of the patients showed fever symptoms when they first saw doctors.
The study, produced by at least three dozen researchers from Chinese hospitals and medical schools led by Dr Zhong Nanshan, a Chinese epidemiologist who discovered the SARS coronavirus in 2003, showed that much is still unknown about the deadly virus named 2019-nCoV.
