There is a virus that can sit silently in your liver for decades, causing no symptoms while it does its damage. Roughly 262,000 people in Canada are living with it, and many have no idea.
That virus is hepatitis B, and new reporting from CBC News shows how doctors and researchers in Alberta have rebuilt the way it gets found and treated, putting hepatitis B testing at the centre of a model the rest of the country may want to copy. This is what they changed and why it matters well beyond Alberta.
Why did this need fixing in the first place
Hepatitis B spreads through contact with blood and other body fluids, and when it goes untreated, it can become chronic and silent, eventually causing liver scarring, cirrhosis and liver cancer. It is estimated to be behind 56 percent of liver cancer cases worldwide, and about 34,000 people in Alberta are living with it. The problem was never a lack of treatment, since medication can suppress the virus to undetectable levels. The gap was hepatitis B testing, diagnosis and referral- everything that comes before treatment.
Dr. Abdel-Aziz Shaheen of the University of Calgary worked with geographers to map where cases were concentrated and found hot spots that closely matched where newcomers have settled over the past two decades, which fits the picture since most cases originate outside the province. Dr. Rachel Talavlikar, a family doctor and director at the Calgary Refugee Health Clinic, noted that a typical family doctor with a panel of 2,000 patients might only ever see a handful of cases, which makes it easy to miss, a screening challenge shared with imported infections behind Canada's tightened Ebola border rules. The research also exposed a second gap in testing for hepatitis D, the more aggressive form that can only exist alongside B.
What did Alberta change, and what Alberta changed to close the gap
Two fixes stand out. The first is speed. Hepatologists at the University of Calgary published a study this year showing they had cut the wait to see a liver specialist from over a year and a half down to about six weeks, which Shaheen says makes Calgary the first city in Canada to pull that off, a rare bright spot against the backdrop of long specialist waits nationwide. Talavlikar says that speed is everything for her patients, because people lose contact with the health system while they wait, especially newcomers juggling jobs, family and a new language.
The second fix is structure. Dr. Carla Coffin, a hepatologist and clinician scientist at the University of Calgary, helped create a primary care pathway, a step-by-step guide that tells family doctors exactly who to test, who benefits from treatment and how to follow up. One built-in change addresses the delta gap directly, since the pathway now recommends automatic hepatitis D testing whenever someone tests positive for B. Coffin says that gap is closing, with a fourfold increase in referrals for delta testing.
What does this mean for you, and what this means for you wherever you live
The lesson in this story is that this is a silent disease, and silence is exactly why testing matters. By the time symptoms appear, serious liver damage may already be underway, while a simple blood test can catch it years earlier, when treatment can suppress the virus completely. It is the same silent-until-late pattern seen in other conditions worth catching early, like the public health emergencies that build before anyone notices.
If you are wondering whether hepatitis B testing applies to you, a few simple risk factors answer it. If you were born in a country where hepatitis B is common, if you have never been tested, or if you are unsure whether you were vaccinated as a child, that is a quick and worthwhile conversation with a doctor. Canada has had universal infant vaccination since the 1990s, so the highest-risk group is adults who arrived before or outside that coverage.
Frequently asked questions
Who should get hepatitis B testing in Canada?
Testing is worth discussing if you were born in a country where hepatitis B is common, have never been tested, or are unsure whether you were vaccinated as a child. Because most cases in Canada originate outside the country and the infection is often silent, adults who arrived before or outside routine infant vaccination are a key group to test.
Why is hepatitis B so dangerous if it has no symptoms?
It can sit silently in the liver for decades while causing damage, so people often feel fine until scarring, cirrhosis or liver cancer has set in. It is estimated to be behind 56 per cent of liver cancer cases worldwide. A simple blood test can catch it years earlier, when medication can suppress the virus completely.
What is hepatitis D and why does it matter?
Hepatitis D, also called delta, can only infect people who already have hepatitis B. It is the more aggressive form, with a higher likelihood of serious liver damage and cancer. Testing for it has historically been scattered, which is why Alberta's new pathway recommends automatic hepatitis D testing whenever someone tests positive for hepatitis B.
How did Calgary cut the liver specialist wait to six weeks?
University of Calgary hepatologists redesigned the pathway from referral to specialist and published results showing the wait dropped from over 18 months to about six weeks, which researchers say makes Calgary the first Canadian city to achieve it. A structured primary care pathway telling family doctors who to test and treat was central to the change.
Where to get tested
If you do not have a family doctor, you can find a walk-in clinic near you with current wait times, or read more conditions and treatment coverage on the Medimap Health Hub, so getting that test on the books takes minutes instead of months.
