There is no need to cancel your trip to Wuhan, where a viral disease outbreak has occurred, but do follow the advice from the Ministry of Health (MOH) and monitor the situation there, said Professor Leo Yee Sin, executive director of the National Centre for Infectious Diseases (NCID).

As of yesterday morning, 44 patients had been hit by the mysterious flu-like virus of "unknown origin", and 11 of them were critically ill, according to the latest statement from the Wuhan Municipal Health Commission. It also said that fever was the main symptom, and a few patients had difficulty breathing.
