MANILA - The 2019 Novel Coronavirus has been identified as the cause of an outbreak of respiratory illness that has spread from China and 24 other countries.
As of February 4, it has taken the lives of at least 425 people in China alone.
Here is the timeline of the 2019-nCoV outbreak:
December 31, 2019
China said it is investigating an outbreak of viral pneumonia originating in the city of Wuhan in Hubei province.
At that time, there were at least 27 cases of viral pneumonia in Wuhan.
The outbreak led to speculations of a disease similar to Severe Acute Respiratory Syndrome, a highly contagious respiratory disease, which killed 349 people in mainland China and another 299 in Hong Kong in 2003.
January 5, 2020
The Philippines' Department of Health ordered a tighter screening of travelers amid reports of a "mysterious disease" from China, which has affected 44 persons at that time.
The illness was described as something similar to "viral pneumonia of unknown origin."
January 6, 2019
China said the mysterious viral pneumonia is not the flu-like virus SARS, which killed hundreds in 2003.
Authorities said the infection in Wuhan broke out between December 12 and 29, with some of the patients employed at a seafood market in the city that has since been closed for disinfection.
January 9, 2020
The World Health Organization said the pneumonia cases in China may be due to a new kind of coronavirus.
Coronaviruses are a large family of viruses that can cause infections ranging from the common cold to Severe Acute Respiratory Syndrome (SARS). Some of the virus types cause less severe disease, while some - like the one that causes Middle East Respiratory Syndrome (MERS) - are far more severe.
January 11, 2020
China reported the first death due to the new coronavirus.
The patient was a 61-year-old man who died from pneumonia. He was a regular buyer at the seafood market, who had been previously diagnosed with abdominal tumors and chronic liver disease.
Forty-one others have also been diagnosed with the virus.
January 13, 2020
The World Health Organization confirmed the first case of the new coronavirus in Thailand.
The person travelling from Wuhan, China had been hospitalized in Thailand after being diagnosed with mild pneumonia.

The World Health Organization (WHO) said it was declaring the China coronavirus outbreak that has killed 170 people in China a global emergency, as cases spread to 18 countries.
The United States reported its first case of person-to-person transmission, the fifth country outside China to do so. Experts say cases of person-to-person transmission outside China are especially concerning because they suggest greater potential for the virus to spread further.
The number of confirmed deaths from China's coronavirus outbreak has risen to 212 after worst-hit Hubei province reported 42 new fatalities on Friday.
Meanwhile, Philippine President Rodrigo Duterte ordered a ban on travelers from China's Hubei province as authorities monitor 31 people who traveled to China recently and showed symptoms related to the new coronavirus, the Department of Health (DOH) said.
The tally includes a 38-year-old woman from Wuhan, China -- the epicenter of the outbreak -- who earlier tested positive for the 2019 Novel Coronavirus acute respiratory disease (2019-nCoV ARD) becoming the first confirmed case in the Philippines, said Health Undersecretary Eric Domingo.

Hours before the WHO made the announcement, the Philippine government imposed a ban on travelers from China and its territories as the new coronavirus' toll continued to climb in the mainland.
The ban covers all foreigners arriving from China, Hong Kong and Macau, including those who visited these areas within 14 days, Executive Secretary Salvador Medialdea said in a statement.
