Outbreaks in Europe, the Middle East and Asia are fueling global fears that the virus is taking root far beyond China. An Iranian lawmaker said 50 have died in the city of Qom, though the Health Ministry disputes that claim. Meanwhile, Italy's now home to 150 cases — forcing officials to lock down 10 towns and cancel Venice's famous carnival — while South Korea's infections have jumped to 833. Back in China, authorities eased some emergency measures as the number of new cases continues to fall.
How are countries responding? Many have imposed travel restrictions for visitors from China or Asia, though the outbreak could pose entirely new policy challenges for a politically chaotic country like Italy.
