On December 31, 2019, a cluster of cases of pneumonia was reported in Wuhan, China, and the cause has been confirmed as a new coronavirus that has not previously been identified in humans. This virus is now known as the 2019 Novel Coronavirus or 2019-nCoV.
On January 25, 2020, the Government of Ontario reported the first case of 2019 nCoV in Canada. The case occurred in a person who had been in the city of Wuhan in the 14 days prior to becoming ill. Appropriate infection prevention and control measures were followed. On January 27, the Government of Ontario reported that the individual’s wife tested positive for the 2019-nCoV. She has been in self-isolation at home since her husband was identified as a case. Close contacts of these cases will be notified, monitored for signs of illness, and given instructions for what to do if they become ill by local public health authorities.
