In Wuhan, the central Chinese city that's ground zero of the deadly new virus spreading through the country, a sense of fear is rapidly taking hold.
On Thursday morning, the city's some 11 million residents woke to learn it's now on lockdown, with public transport halted, flights out canceled and trains not running right on the eve of the Lunar New Year holiday that traditionally unites families for days of feasting.
It's a dramatic escalation for Wuhan, which has found itself at the epicenter of a potentially global health crisis after a market selling freshly slaughtered meat and live animals was identified as the source of an outbreak that's killed over a dozen people and sickened hundreds.
