On 23 January, the US ordered the departure of all non-emergency US personnel and their family members from the city of Wuhan in Hubei province, where the virus originated.
Less than a week later, the US allowed for the voluntary departure of non-emergency personnel and relatives of US government employees from China.
On 30 January, the World Health Organization (WHO) declared a global health emergency over the new virus.
Following this, the US ordered the departure of all US personnel family members under the age of 21 in China.
Any US citizen who has been in Hubei province will be subject to 14 days' quarantine upon returning to the US.
What are other countries doing to stem the outbreak?
On Monday, Hong Kong said it was suspending from midnight local time (16:00 GMT) 10 out of 13 border crossings with mainland China.
Various countries have imposed varying travel restrictions and other preventative measures, including:
Denying entry to all foreign visitors who have recently been to China: US, Australia, Singapore
Denying entry to foreigners travelling from mainland China: New Zealand, Israel. (Russia will also apply these restrictions, though not through Moscow's Sheremetyevo airport)
Denying entry to foreigners who have visited Hubei province: Japan, South Korea
Temporarily suspending all flights to mainland China: Egypt, Finland, Indonesia, the UK, Italy
Closing the border with China: Mongolia, Russia (partially)
The body that represents some of the world's largest cruise ship operators, the Cruise Lines International Association, announced on Monday that passengers and crew members who had recently travelled to China would not be allowed to board vessels.
How did China react to the US measures?
In a news briefing on Monday, Chinese foreign ministry spokesperson Hua Chunying said the US actions "could only create and spread fear" instead of offering assistance.
She said the US was the first country to impose a travel ban on Chinese travellers and the first to suggest a partial withdrawal of its embassy staff.
"It is precisely developed countries like the US with strong epidemic prevention capabilities... that have taken the lead in imposing excessive restrictions contrary to WHO recommendations," Ms Hua said, according to a Reuters report.
But Ms Hua also said that China urgently needed "medical masks, protective suits and safety goggles".
Do the travel bans work?
Global health officials have advised against the bans.
The WHO has warned that closing borders could even accelerate the spread of the virus, if travellers enter countries unofficially.
"Travel restrictions can cause more harm than good by hindering info-sharing, medical supply chains and harming economies," the head of the WHO, Dr Tedros Adhanom Ghebreyesus, said last week.
The WHO instead recommends introducing screening at border crossings.
On Monday, Dr Tedros again praised China for its commitment to fighting the coronavirus, stressing that the only way to defeat it was for all countries to work together "in a spirit of co-operation".
How deadly is the virus?
More than 75,000 people may have been infected in the city of Wuhan, experts say.
But estimates by the University of Hong Kong suggest the total number of cases could be far higher than the official figures.
A report on the early stages of the outbreak by the Lancet medical journal said most patients who died from the virus had pre-existing conditions.
The report found that, of the first 99 patients treated at the Jinyintan Hospital in Wuhan, 40 had a weak heart or damaged blood vessels. A further 12 had diabetes.
Most people infected are likely to fully recover - just as they would from a normal flu.
An expert at China's National Health Commission (NHC) said that one week was sufficient for a recovery from mild coronavirus symptoms.
