You have to get infected blood into your blood stream. There are several ways to do that, that don't involve IV drug use.
I just wanted to add the with intravenous drug use you are at a higher risk of contracting a super infection which is having more than one genotype.
"Is intravenous drug use the only way to get hepC. genotype 3"
No and all genotypes are spread in the same fashion, blood to blood contacct
Transmission / Exposure
How is Hepatitis C spread?
Hepatitis C is usually spread when blood from a person infected with the Hepatitis C virus enters the body of someone who is not infected. Today, most people become infected with the Hepatitis C virus by sharing needles or other equipment to inject drugs. Before 1992, when widespread screening of the blood supply began in the United States, Hepatitis C was also commonly spread through blood transfusions and organ transplants.
People can become infected with the Hepatitis C virus during such activities as
Sharing needles, syringes, or other equipment to inject drugs
Needlestick injuries in health care settings
Being born to a mother who has Hepatitis C
Less commonly, a person can also get Hepatitis C virus infection through
Sharing personal care items that may have come in contact with another person’s blood, such as razors or toothbrushes
Having sexual contact with a person infected with the Hepatitis C virus
Can Hepatitis C be spread through sexual contact?
Yes, but the risk of transmission from sexual contact is believed to be low. The risk increases for those who have multiple sex partners, have a sexually transmitted disease, engage in rough sex, or are infected with HIV. More research is needed to better understand how and when Hepatitis C can be spread through sexual contact.
Can you get Hepatitis C by getting a tattoo or piercing?
A few major research studies have not shown Hepatitis C to be spread through licensed, commercial tattooing facilities. However, transmission of Hepatitis C (and other infectious diseases) is possible when poor infection-control practices are used during tattooing or piercing. Body art is becoming increasingly popular in the United States, and unregulated tattooing and piercing are known to occur in prisons and other informal or unregulated settings. Further research is needed to determine if these types of settings and exposures are responsible for Hepatitis C virus transmission.
