Among the 170 patients under treatment in hospitals, 126, 35, and 9 are in mild, severe, and critical condition, respectively (http://www.thatsmags.com/china/post/30618/new-coronavirus-spreads-to-over-130-in-china-death-toll-rises). In addition, two patients in Thailand, one in Japan, and one in South Korea, were detected positive for 2019-nCoV. They did not visit the specific seafood market, but might have close contact with some pneumonia patients during their trip in Wuhan, raising the concern of limited human-to-human transmission of 2019-nCoV (http://www.thatsmags.com/china/post/30618/new-coronavirus-spreads-to-over-130-in-china-death-toll-rises).
