The World Health Organization has declared the crisis a global health emergency, and the first foreign death from the virus was reported in the Philippines on Sunday.
The virus has since spread to more than 24 countries, despite many governments imposing unprecedented travel bans on people coming from China.

The centre confirmed that a suspected case, who returned from China last week, had carried out a routine medical check as requested by his employers, and he showed no symptoms of illness, neither was he diagnosed with the virus.
