Primary Modes Of Hepatitis C Transmission
Any activity that exposes you to blood infected with the hepatitis C virus puts you at risk. [2]
This can include several activities, from sexual practices to injected drug use. [2]
1. Sexual Activity
Contracting hepatitis C during sex is quite uncommon, but it can still happen. An HCV infection can occur if your partner is infected with the virus and spreads it through an open wound or sore.[3]That said, there are several factors that can put you at a higher risk of acquiring hep C transmission sexually. These include [3]:
- Having a sexually transmitted infection (STI)
- Having sex with multiple partners
- Having anal sex
- Having sex while menstruating
- Having sex without protection, like a condom
- Having rough sex that causes tears or scratches
Studies have also found that men who have sex with men (MSM) are also at a higher risk of contracting the virus through sexual transmission. [3]
To lower your chances of acquiring hepatitis C through intimacy, avoid any sex acts that may cause bleeding, such as using toys or drugs while having sex. Fortunately, a hepatitis C infection can not be spread through physical contact like hugging or kissing. [2]
2.Blood Transfusion
Worldwide, blood transfusions are one of the main causes of the spread of hepatitis C, particularly in developing countries.4 Fortunately, in the United States, advances in blood transfusion technology and regular HCV antibody (Ab) blood screenings have greatly reduced the number of blood transfusion hepatitis C cases. [5]In contrast, studies conducted during the ‘60s and ‘70s identified that 25% of patients with the hepatitis C virus were infected through transfusion-transmission.5 These numbers only decreased as medical personnel became more stringent with their donor qualifications. Namely, they excluded those who tested positive for hepatitis B, which is primarily transmitted through sexual activity, and human immunodeficiency virus (HIV). [5]
All that said, hepatitis C can still be transmitted in the early stages of the infection when the virus does not appear on blood screenings. [5]
It’s also believed that the virus can survive outside of the body, within dry patches of blood, for weeks. [6]
3. Injection Drug Use
Sharing unsterilized syringes and needles to inject drugs puts drug users at a significant risk of contracting hepatitis C if they’re using the same equipment as a person with the virus.7 In a study that observed hepatitis rates in 88 countries (which comprises 85% of the global population), researchers found that 0.2% of patients who contracted the virus also injected drugs. [7]Drug use is considered the leading risk factor for contracting hepatitis C in the United States. And, within the country, a third of young people who inject drugs have been exposed to the virus.[8] Injection drug use is also correlated with opioid misuse, unemployment, poverty, incarceration, and homelessness.
