The World Health Organization (WHO) has urged governments around the world to prepare for local outbreaks of the coronavirus.
The February 1 announcement came as China raised the death toll in that country from the virus to 259. China reported 11,791 confirmed cases of the virus, making it worse than the 2002-03 outbreak of SARS, or Severe Acute Respiratory Syndrome.
The WHO earlier in the week declared a global health emergency over the flu-like coronavirus. The organization has expressed concern that some cases outside China could involve human-to-human transmission of the virus.
"Countries need to get ready for possible importation in order to identify cases as early as possible and in order to be ready for domestic outbreak control, if that happens," the WHO representative in Beijing, Gauden Galea, told journalists.
