B.C. has recorded its first case of novel coronavirus from China, B.C. Provincial Health Officer Bonnie Henry says.
The patient, a man in his 40s who regularly visits China, is “doing well in isolation at home,” Henry told a news conference at the B.C. Centre for Disease Control in Vancouver Tuesday.
B.C.’s first patient visited Wuhan, the Chinese city where the new virus was first identified, and reported symptoms after he returned to his home in the Vancouver Coastal Health Region.
The man was aware of the risk and “self-isolated” after his return, Henry said. “This person was not symptomatic on his flight, and there is no risk” to other people, she said.
Canada’s Foreign Minister Francois-Phillippe Champagne said Tuesday the federal government is in contact with Chinese authorities and is part of an international effort to control the spread of the new respiratory virus.
Health officials say the world-wide sharing of information and speed of diagnostic tests has improved greatly since the 2003 outbreak of another new viral strain, called severe acute respiratory syndrome (SARS).

Henry warned against social media rumours about the spread of the disease, and said the public’s best source of information is the frequently updated coronavirus page at the B.C. Centre for Disease Control.
Henry said B.C.’s first confirmed patient arrived back in the Vancouver area last week, but declined to say which day. The patient underwent testing that indicated he has the coronavirus strain that has prompted China to isolate several cities to contain its spread.

Henry, who worked on the 2003 SARS epidemic and also on containing the ebola virus in Africa, said the novel coronavirus is less easily transmitted than common influenza, because its receptors are deeper in the lung. That makes it less likely to contract it from touching contaminated surfaces rather than direct contact.
“As long as you clean your hands before you touch your face or your mouth, you’re not going to get that virus inyour body,” Henry said.
People who have respiratory symptoms can reduce their risk of transmitting it by covering their mouths when they cough or wearing a mask. If they have travelled to affected areas, they should call 8-1-1 to report any symptoms.

In February 2003, the Chinese government notified the World Health Organization of 305 cases of SARS, with five deaths and 105 health-care workers infected. In the early stages, China provided information to WHO only on Guangdong province, where the virus was believed to have originated, and discouraged news reports of other infection sites in the country.
SARS spread to Hong Kong and from there to Toronto, from people who came into contact with each other at the same Hong Kong hotel. More than 400 Canadians were eventually diagnosed with SARS and 44 died in an epidemic that killed 800 people world-wide.
