In an attempt to curb the rapid spread of coronavirus, which health officials determined can move from human to human through the air or by touch, many popular attractions in and around China have been closed or are preparing to close to the public.
Health officials have refused to comment on reports of several potential cases under observation.
The North Carolina Division of Public Health is arranging testing for the novel coronavirus at the Centers for Disease Control and Prevention (CDC). Overall, the CDC is now investigating 63 people (including the two that tested positive) in 22 states for a possible infection with the new virus. Most people who contract the virus appear to experience milder symptoms. Roughly 35 million people live in the quarantined cities, near Wuhan, where the virus is thought to have emerged.

Testing for the 2019 coronavirus is only available at the CDC now.
The virus infects the lungs, and symptoms start with a fever and cough.
While human-to-human transmission has been reported within China, Ghebreyesus said, it so far seems to be mostly limited to close family members and health-care workers.
More than 2,000 returning travellers had been screened at airports across the US.
