BEIJING/SHANGHAI (REUTERS) - Police in China have detained a woman for "deliberately concealing" her contact with someone from an area stricken by the coronavirus and jeopardising efforts to stop its spread, the Xinhua news agency reported on Tuesday (Feb 4).

China has imposed sweeping measures to try to halt the virus including virtually locking down the central province of Hubei, where the virus emerged in December, and asking anyone who has visited there to isolate themselves for 14 days.
