The coronavirus moved uncomfortably closer to B.C. last week, with one confirmed case in the Seattle area, and another suspected case in Vancouver.
And while that is reason for concern, it is certainly no reason for panic.
The numbers add to a growing list of individuals now confirmed to have contracted this new and potentially deadly respiratory illness.
At writing, nearly 900 cases had been identified worldwide, resulting in 26 deaths.
Despite a colossal effort in China to contain the outbreak to the city of Wuhan where it was first reported, the disease has spread.
Health officials – both here and internationally – have yet to label the outbreak an “international health emergency”.
But that may change.

This latest virus is part of the same family responsible for SARS (Severe Acute Respiratory Syndrome).
That outbreak, which came from China in 2002, was blamed for 44 deaths in Canada and more than 800 worldwide.
This latest outbreak comes at a dangerous time in China. The Lunar New Year is usually a time of travel, where families attempt to spend time together.
That’s not happening in at least 10 cities where China has imposed a quarantine affecting over 30 million people.
The fear is that human-to-human spread could accelerate transmission of the disease faster than efforts to contain it.
And while we have been fortunate in past outbreaks like SARS and the similar MERS a few years ago, the potential for disaster is real.
Just last year the world marked the centenary of the 1918 influenza outbreak. The spread of that disease, believed to have sprung from the mud and trenches of the First World War, was aided by demobilization. It would eventually kill more people worldwide (40 to 50 million) than the war itself.
Since then our understanding of disease transmission and our ability to respond has improved dramatically. Even China has responded much more aggressively to this outbreak than it did to the 2002/03 SARS outbreak.
There is a fine line health officials must walk between being cautious and alarmist.
Already in Vancouver there are reports that filter masks, normally used for construction, are being snapped up by concerned residents. There are stories, too, about people curtailing travel plans to China.

Vancouver International Airport, meanwhile, has been identified as one of three likely Canadian entry points for the disease. Although YVR has yet to introduce cameras that can detect elevated body temperatures like some U.S. airports, it is working with the Public Health Agency of Canada to introduce several new measures. Anyone experiencing flu-like symptoms, for example, must report that information to a customs officer. There is additional signage, and airport staff have stepped up cleaning of key areas.
But as health officials point out, the best defence against this or any other virus begins with the simple precautions we can take, like washing our hands and coughing or sneezing into our sleeve.
The coronavirus is concerning because we have never seen it before.
However, we do see viruses all the time. The common flu kills up to 650,000 people every year (mostly our most vulnerable), according to the World Health Organization.
There are simple steps we can all take to prevent the spread of these viruses, like vaccinations, proper hygiene, and staying away from others when we are sick.
The coronavirus outbreak is reminder of the importance of these steps.
