It is not too early to do some contingency planning as to the measures that might need to be taken where you are responsible for emergency management. I remember how people discounted the potential arrival of ebola here in the United States and the turmoil that the relatively few cases caused within the medical community, especially when it came to infection control.
From the Centers for Disease Control and Prevention (CDC):
"2019 Novel Coronavirus (2019-nCoV) is a virus (more specifically, a coronavirus) identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China. Early on, many of the patients in the outbreak in Wuhan, China reportedly had some link to a large seafood and animal market, suggesting animal-to-person spread. However, a growing number of patients reportedly have not had exposure to animal markets, indicating person-to-person spread is occurring. At this time, it’s unclear how easily or sustainably this virus is spreading between people."
Significantly, there is this news, "Ma, the Chinese health minister, told reporters Sunday that the virus is infectious during its incubation period, meaning that a person could spread it to others before experiencing symptoms. That's a significant difference from the SARS (severe acute respiratory syndrome) coronavirus, which began in China in 2002 and spread globally, killing 774 people."
