Of the investigated cases across 26 states, 32 people had tested negative, the CDC said.
The second patient with a positive test result is the wife of the first patient, who is a man in his 50s. But in Japan, a man in his 60s apparently contracted the virus after driving two groups of tourists from the city earlier in January, the health ministry said. "Given the fact that she has been in self-isolation, the risk to Ontarians remains low".
In a conference call Thursday, Theresa Tam, chief public health officer of Canada, said "there is no recommendation to wear a mask when you're going about your daily regular activities".
"Whether it's novel coronavirus, influenza, other respiratory diseases, if you're sick, stay home and don't go out and socialize", Williams added. It remains to be seen whether the virus is as risky as the common flu, which kills thousands every year in Canada alone. That test has yet to be verified by a federal lab in Winnipeg so the case is being referred to as a "presumptive" case, and not an official one.
The latest presumptive case is a man in his 40s from British Columbia.
"The patient will not be discharged until we can be assured that they are making a full recovery and no longer pose any risk to public health", Jerome Leis, medical director of infection prevention and control at Sunnybrook, said on Sunday.
That meeting was scheduled before the first case of the troubling virus was confirmed in a patient in Toronto. He is recovering at home.
Officials in that country have reported the illness has killed at least 81 people and infected more than 2,700 others. Since then, the man has been in stable condition in isolation at Toronto's Sunnybrook Health Sciences Centre.
"The two cases are a married couple who arrived at Pearson International Airport on January 22", she explained. He did not specify how many people were contacted.
The outbreak prompted officials to cancel Lunar New Year celebrations across China, and quarantine a number of cities within Hubei province, including Wuhan.
The dramatic spread of the coronavirus has paved the way for some comparisons with the SARS outbreak in 2003 which led to the death of as many as 800 individuals around the globe and dozens in Toronto alone.
But Tam said other people on the flight or airport that were not close to the patient should not be overly concerned.
While officials say there's no reason for Canadians to panic over the Wuhan coronavirus, the City of Mississauga says Peel Public Health is monitoring the situation. "People are self-identifying and we continue to make sure the system is working".
Symptoms of the coronavirus can be quite similar to those associated with flu and colds - a fever and/or cough, along with difficulty breathing. World Health Organization says it has been working with Chinese authorities and global experts from the day they were informed, to learn more about the virus, how it affects the people who are sick with it, how they can be treated, and what countries can do to respond.
