China says the Wuhan virus, unlike SARS, is infectious during its incubation period

The Chinese government warned today (Jan. 26) the new coronavirus spreading through the country appears to be contagious as much as two weeks before symptoms appear. In a press briefing, the head of China’s National Health Commission, Ma Xiaowei, said scientists’ understanding of the virus was still “limited” and the outbreak was likely to continue for “some time,” according to the South China Morning Post. Most of the patients originally diagnosed with the virus were exposed at the Huanan seafood market in Wuhan, which also trades in wild animals believed to be the source of the infection.
