An unidentified form of pneumonia that recently broke out in the central Chinese city of Wuhan has put neighboring regions on high alert, as authorities in China scramble to identify the source of the mysterious virus.
On Jan. 6, Hong Kong’s public hospitals admitted six more patients who presented symptoms of respiratory infection or pneumonia, bringing the total to 21, according to the city’s Hospital Authority. The patients have been to Wuhan in the past 14 days.
