There's still a lot we don't know about the coronavirus, and scientists internationally are racing to gather data and develop a treatment.
Here's what we can tell you so far:
From CNN Business' Laura He in Hong Kong
Chinese stocks plunged Monday on the first day investors could react to the coronavirus outbreak in more than a week.
The Shanghai Composite opened 9% lower. The Shenzhen Component Index also plummeted 9% at open. Both are still down more than 7%.
Stock exchanges in Shanghai and Shenzhen had been closed since January 24 for the Lunar New Year. Markets elsewhere fell sharply last week as fears about the virus escalated. More than 14,300 people have been infected, the vast majority of them in mainland China.
China said before markets opened that it would pump billions of dollars into its markets to keep them stable. The People's Bank of China said Sunday that it would inject $1.2 trillion yuan ($173 billion) into the Chinese markets using the purchase of short-term bonds to shore up banks' ability to lend money. The measure will help maintain "reasonably ample liquidity" in the banking system and keep currency markets stable.
The net amount of liquidity being injected into the markets will be much lower. According to Reuters calculations using central bank data, more than $1 trillion yuan worth of other short-term bond agreements will mature Monday. That brings the net amount of cash flooding into the markets down to 150 billion yuan ($22 billion).

The first case of coronavirus was detected in central China in early December. Now, nearly two months later, it's a full-blown global emergency, with more than 17,205 confirmed cases across the world.
Here's a look back at how we got here:

Canadian officials have fielded 325 requests for departure assistance from Hubei province in China due to the Wuhan coronavirus, according to a statement obtained by CNN from Global Affairs Canada. Ottawa is attempting to charter a plane to take Canadians from Wuhan back to Canada, the statement said.
There are currently 543 Canadians in Hubei who have registered with the voluntary Registration of Canadians Abroad service. Since registration is voluntary, this number is not a complete picture of Canadians in the region or in China, according to the statement.
Only Canadian citizens who have entered China with a Canadian passport will be allowed to board the plane back to Canada, Global Affairs Canada said. Additionally, Canadian citizens will need to have a valid Canadian passport along with a valid Chinese visa to board the plane. Canadians appearing with symptoms will not be able to board the aircraft, according to Global Affairs Canada. The country is still determining protocols for Canadians once they arrive in Canada.

Gross gaming revenue in the Chinese territory of Macao, the world's biggest gambling destination, was down 11.3% in January 2020 compared to January 2019, authorities there said Monday.
Macao has confirmed several cases of the virus, and the outbreak has had a devastating impact on tourism in the gambling enclave, which relies heavily on mainland Chinese visitors.
The government in the city has taken significant steps to stop the spread of the virus. All residents of Hubei province and non-residents who traveled to Hubei in the past 14 days will be denied entry to Macao, until they show a doctor's letter certifying they are clear, according to Secretary for Administration and Justice Cheong Weng-chon.

China’s National Health Commission said that at the end of Sunday, the total number of confirmed coronavirus cases in mainland China stands at 17,205, up 2,829 from the previous day.
The death toll in China stands at 361 as of Sunday, more than the amount of people who died in the country during the 2003 SARS outbreak. One person died as a result of the virus in the Philippines on Saturday -- the death reported outside China.

Doctors in Thailand say they have successfully treated one Wuhan coronavirus patient with a combination of antiviral drugs, according to a briefing on Sunday from the Ministry of Health.
Dr. Kriangsak Atipornwanich, a doctor at Rajavithi Hospital in Bangkok, said he treated a 71-year-old female patient from China with a combination of drugs used in HIV and flu treatments. He said the patient had previously been treated with only anti-HIV drugs.
“I had treated a patient with severe condition, and the result has been very satisfactory. The patient’s condition has improved very quickly within 48 hours. And the test result has also changed from being positive into negative within 48 hours as well,” Atipornwanich said.
Officials at the press conference said the latest lab test has showed there’s no trace of the virus in the patient’s respiratory system.
Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases at the US National Institutes of Health, told CNN last week there are currently no proven effective drugs to treat the virus.
Hospitals in Beijing have reported using the same drugs given to HIV and AIDs patients are part of treatment for the Wuhan coronavirus, though it is unclear if they have been successful.
