Who is At Risk for Hepatitis C?

Knowing who is at risk for hep C is one of the most important steps in preventing its spread. Hepatitis C is a contagious liver disease caused by the Hepatitis C virus (HCV) that can cause serious complications including cirrhosis and liver cancer if left untreated. According to the Public Health Agency of Canada, an estimated 250,000 Canadians are living with hepatitis C, and many remain undiagnosed. Canadian Addiction Treatment Centres offers same-day hepatitis C screening with results from a simple finger poke.
How is Hep C Spread?
One of the most common ways Hep C is spread is through contact with blood from an infected person. This includes sharing needles, syringes, or other drug equipment. Although rare, sexual transmission is also possible, as well as being born to a mother who has Hepatitis C. It can also be spread by coming into contact with contaminated objects such as razors or toothbrushes. Additionally, receiving tattoos in unsterile environments may increase the risk of contracting hepatitis C if there was blood present that was previously exposed to HCV-infected blood.
While it’s possible for Hepatitis C to be transmitted through saliva and other bodily fluids, this type of transmission is one of the less common ways Hep C is spread—as long as there are no open sores or cuts in the skin that could allow infected fluid to enter the body. Healthcare workers are at a higher risk of exposure than most people, due to their frequent contact with patients’ blood and bodily fluids while on duty. However, proper safety protocols including sterile gloves should reduce any potential risks significantly.
It is important for anyone who may have been exposed to the virus—even if they do not currently show symptoms—to get tested and seek treatment right away before any complications arise. This will prevent the infection from spreading further in their bodies.
Can You Be Asymptomatic and Spread Hepatitis C?
It’s possible to be infected with the Hepatitis C virus and be asymptomatic—meaning you have no symptoms of the infection. Most people who are infected with HCV do not experience any symptoms for several months or even years after being exposed to the virus. That means that many individuals may unknowingly spread the virus without realizing they have it due to a lack of noticeable signs and symptoms.
Being asymptomatic does not mean that an individual cannot transmit hepatitis C through contact with their bodily fluid. Those who are unaware they have contracted HCV could potentially spread it more easily than someone who has been diagnosed and is taking steps to prevent transmission. Therefore, it is important to understand how Hepatitis C can be passed between people even if neither person experiences any visible signs or symptoms of the disease.
How Soon Will Hep C Show Up After Exposure?
Knowing how soon HCV will show up after exposure to the virus is important for those at risk. They must seek treatment right away before any complications arise from the infection spreading further in their bodies.

Who is Most at Risk for Hepatitis C?
People who use injection drugs are particularly vulnerable to the Hepatitis C virus due to their increased likelihood of sharing needles, which can spread the virus if they come into contact with infected blood. People who received a blood transfusion before 1992 may also be at high risk, as safety protocols were not yet available that could adequately screen out potentially contaminated donations during this period.
Additional groups with elevated risk of hepatitis C exposure include people born between 1945 and 1965, people who have been incarcerated, people living with HIV, and people on hemodialysis. According to PHAC, people who inject drugs account for the majority of new HCV infections in Canada.
Can You Get Hep C More Than Once?
Yes, it’s possible to contract Hepatitis C (HCV) more than once. While the virus typically remains in an infected person’s body for life, recurrence of HCV infection is not unheard of.
Transmission of hepatitis can occur more than once if a person encounters the virus again and has weakened immunity due to other conditions. If their immune system does not recognize it or cannot fight off the new strain, they may be re-infected. Additionally, individuals who have undergone organ transplants may also encounter this issue, since there is potential for exposure through donor tissues containing traces of Hepatitis C.
How to Prevent Hepatitis C
One of the most important steps to prevent Hepatitis C (HCV) is to be aware of the potential risks associated with contracting this virus and take action to protect oneself from exposure. Those at high risk for Hepatitis C infection must take extra precautions when engaging in activities outside their home which may place them at greater risk of coming into contact with contaminated objects or fellow individuals carrying the virus. This includes avoiding sharing needles/syringes used for injection drugs, having protected sexual activity, and only receiving tattoos from reputable tattoo shops.
Additionally, those living in close quarters, such as military personnel, inmates, and students attending college dormitories should also maintain personal hygiene regularly. This includes washing hands frequently and using disposable paper towels instead of cloths.

Testing options include rapid point-of-care tests available at clinics like CATC, as well as comprehensive laboratory screenings that track viral load over time and help monitor response to treatment.
Knowing your status is the first step toward protecting your health and preventing transmission to others.

Frequently Asked Questions: Who Is at Risk for Hep C?
Q: Who is most at risk for hep C in Canada?
A: The highest-risk group is people who inject drugs and share needles or equipment. Other at-risk groups include people who received blood transfusions before 1992, people living with HIV, people on hemodialysis, those who have been incarcerated, and people born to a parent with hepatitis C.
Q: Can you have hep C and not know it?
A: Yes. Most people with hepatitis C have no symptoms for years or even decades. This is why testing is recommended for anyone who may have been exposed, even if they feel completely healthy.
Q: How soon after exposure will hep C show up on a test?
A: Symptoms can appear anywhere from two weeks to six months after exposure, though some people never develop noticeable symptoms. Antibodies typically appear in the blood within 8 to 11 weeks. Follow-up testing may be recommended if an initial test comes back negative shortly after a potential exposure.
Q: Can you get hep C more than once?
A: Yes. Successfully clearing a hepatitis C infection does not provide immunity. Reinfection is possible if exposure occurs again, which is why ongoing harm reduction practices remain important.
Q: Where can I get tested for hep C in Canada?
A: Canadian Addiction Treatment Centres offers same-day hepatitis C screening with results from a simple finger poke. Testing is also available through your family physician, community health centres, and public health units across Canada.
