Hep C - FAQs
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.
Can Hepatitis C be spread within a household?
Yes, but this does not occur very often. If Hepatitis C virus is spread within a household, it is most likely a result of direct, through-the-skin exposure to the blood of an infected household member.
How should blood spills be cleaned from surfaces to make sure that Hepatitis C virus is gone?
Any blood spills — including dried blood, which can still be infectious — should be cleaned using a dilution of one part household bleach to 10 parts water. Gloves should be worn when cleaning up blood spills.
How long does the Hepatitis C virus survive outside the body?
The Hepatitis C virus can survive outside the body at room temperature, on environmental surfaces, for up to 3 weeks.
What are ways Hepatitis C is not spread?
Hepatitis C virus is not spread by sharing eating utensils, breastfeeding, hugging, kissing, holding hands, coughing, or sneezing. It is also not spread through food or water.
Who is at risk for Hepatitis C?
Some people are at increased risk for Hepatitis C, including:
- Current injection drug users (currently the most common way Hepatitis C virus is spread in the United States)
- Past injection drug users, including those who injected only one time or many years ago
- Recipients of donated blood, blood products, and organs (once a common means of transmission but now rare in the United States since blood screening became available in 1992)
- People who received a blood product for clotting problems made before 1987
- Hemodialysis patients or persons who spent many years on dialysis for kidney failure
- People who received body piercing or tattoos done with non-sterile instruments
- People with known exposures to the Hepatitis C virus, such as
- Health care workers injured by needlesticks
- Recipients of blood or organs from a donor who tested positive for the Hepatitis C virus
- HIV-infected persons
- Children born to mothers infected with the Hepatitis C virus
Less common risks include:
- Having sexual contact with a person who is infected with the Hepatitis C virus
- Sharing personal care items, such as razors or toothbrushes, that may have come in contact with the blood of an infected person
What is the risk of a pregnant woman passing Hepatitis C to her baby?
Hepatitis C is rarely passed from a pregnant woman to her baby. About 6 of every 100 infants born to mothers with Hepatitis C become infected with the virus. However, the risk becomes greater if the mother has both HIV infection and Hepatitis C.
Can a person get Hepatitis C from a mosquito or other insect bite?
Hepatitis C virus has not been shown to be transmitted by mosquitoes or other insects.
Can I donate blood, organs, or semen if I have Hepatitis C?
No, if you ever tested positive for the Hepatitis C virus (or Hepatitis B virus), experts recommend never donating blood, organs, or semen because this can spread the infection to the recipient.
What are the symptoms of acute Hepatitis C?
Approximately 70%–80% of people with acute Hepatitis C do not have any symptoms. Some people, however, can have mild to severe symptoms soon after being infected, including:
- Loss of appetite
- Abdominal pain
- Dark urine
- Clay-colored bowel movements
- Joint pain
- Jaundice (yellow color in the skin or eyes)
How soon after exposure to Hepatitis C do symptoms appear?
If symptoms occur, the average time is 6–7 weeks after exposure, but this can range from 2 weeks to 6 months. However, many people infected with the Hepatitis C virus do not develop symptoms.
Can a person spread Hepatitis C without having symptoms?
Yes, even if a person with Hepatitis C has no symptoms, he or she can still spread the virus to others.
Is it possible to have Hepatitis C and not know it?
Yes, many people who are infected with the Hepatitis C virus do not know they are infected because they do not look or feel sick.
What are the symptoms of chronic Hepatitis C?
Most people with chronic Hepatitis C do not have any symptoms. However, if a person has been infected for many years, his or her liver may be damaged. In many cases, there are no symptoms of the disease until liver problems have developed. In persons without symptoms, Hepatitis C is often detected during routine blood tests to measure liver function and liver enzyme (protein produced by the liver) level.
How serious is chronic Hepatitis C?
Chronic Hepatitis C is a serious disease that can result in long-term health problems, including liver damage, liver failure, liver cancer, or even death. It is the leading cause of cirrhosis and liver cancer and the most common reason for liver transplantation in the United States. Approximately 19,000 people die every year from Hepatitis C related liver disease.
What are the long-term effects of Hepatitis C?
Of every 100 people infected with the Hepatitis C virus, about
- 75–85 people will develop chronic Hepatitis C virus infection; of those,
- 60–70 people will go on to develop chronic liver disease
- 5–20 people will go on to develop cirrhosis over a period of 20–30 years
- 1–5 people will die from cirrhosis or liver cancer
Can a person have normal liver enzyme (e.g., ALT) results and still have Hepatitis C?
Yes. It is common for persons with chronic Hepatitis C to have a liver enzyme level that goes up and down, with periodic returns to normal or near normal. Some infected persons have liver enzyme levels that are normal for over a year even though they have chronic liver disease. If the liver enzyme level is normal, persons should have their enzyme level re-checked several times over a 6–12 month period. If the liver enzyme level remains normal, the doctor may check it less frequently, such as once a year.
Who should get tested for Hepatitis C?
Talk to your doctor about being tested for Hepatitis C if any of the following are true:
- You were born from 1945 through 1965
- You are a current or former injection drug user, even if you injected only one time or many years ago.
- You were treated for a blood clotting problem before 1987.
- You received a blood transfusion or organ transplant before July 1992.
- You are on long-term hemodialysis treatment.
- You have abnormal liver tests or liver disease.
- You work in health care or public safety and were exposed to blood through a needlestick or other sharp object injury.
- You are infected with HIV.
What is HIV and Hepatitis C virus co-infection?
HIV and Hepatitis C virus co-infection refers to being infected with both HIV and the Hepatitis C virus. Co-infection is more common in persons who inject drugs. In fact, 50%–90% of HIV-infected persons who use injection drugs are also infected with the Hepatitis C virus
