Hepatitis C is a liver infection caused by the hepatitis C virus (HCV).
Hepatitis C is spread
through contact with blood from an infected person. Today, most people become infected with
the hepatitis C virus by sharing needles or other equipment used to prepare and inject drugs.
For some people, hepatitis C is a short-term illness, but for more than half of people who
become infected with the hepatitis C virus, it becomes a long-term, chronic infection. Chronic
hepatitis C can result in serious, even life-threatening health problems like cirrhosis and liver
cancer. People with chronic hepatitis C can often have no symptoms and don’t feel sick. When
symptoms appear, they often are a sign of advanced liver disease. There is no vaccine for
hepatitis C. The best way to prevent hepatitis C is by avoiding behaviors that can spread the
disease, especially injecting drugs. Getting tested for hepatitis C is important, because
treatments can cure most people with hepatitis C in 8 to 12 weeks.
What is hepatitis?
Hepatitis means inflammation of the liver. When the liver is inflamed or
damaged, its function can be affected. Heavy alcohol use, toxins, some
medications, and certain medical conditions can all cause hepatitis. However,
hepatitis is often caused by a virus. In the United States, the most common
hepatitis viruses are hepatitis A virus, hepatitis B virus, and hepatitis C virus.
What is the difference between hepatitis A, hepatitis B, and hepatitis C?
Hepatitis A, hepatitis B, and hepatitis C are liver infections caused by three
different viruses. Although each can cause similar symptoms, they are
spread in different ways and can affect the liver differently. Hepatitis A is
usually a short-term infection. Hepatitis B and hepatitis C can also begin as
short-term infections, but in some people, the virus remains in the body and
causes chronic (long-term) infection. There are vaccines to prevent hepatitis
A and hepatitis B; however, there is no vaccine for hepatitis C.
The page “What is viral hepatitis?” explains in detail the differences between
hepatitis A, hepatitis B, and hepatitis C.
What is hepatitis C?
Hepatitis C is a liver infection caused by the hepatitis C virus. Hepatitis C can
range from a mild illness lasting a few weeks to a serious, long-term illness.
Hepatitis C is often described as “acute,” meaning a new infection, or
“chronic,” meaning long-term infection.
Acute hepatitis C occurs within the first 6 months after someone is
exposed to the hepatitis C virus. Hepatitis C can be a short-term illness,
but for most people, acute infection leads to chronic infection.
Chronic hepatitis C can be a lifelong infection if left untreated.
Chronic hepatitis C can cause serious health problems, including liver
damage, cirrhosis (scarring of the liver), liver cancer, and even death.
How serious is chronic hepatitis C?
Chronic hepatitis C can be a serious disease resulting in long-term health
problems, including liver damage, liver failure, cirrhosis, liver cancer, and
even death. It is the most common reason for liver transplantation in the
United States. There were 15,713 deaths related to hepatitis C virus reported
to CDC in 2018, but this is believed to be an underestimate.
How likely is it that someone with acute hepatitis C will become chronically
infected?
More than half of people who become infected with hepatitis C virus will
develop a chronic infection.
Is it possible for someone with hepatitis C to get better without treatment
Yes. However, less than half of people who are infected with the hepatitis C
virus clear it from their bodies without treatment. Experts do not fully
understand why this happens for some people.
How common is acute hepatitis C in the United States?
In 2018, a total of 3,621 cases of acute hepatitis C were reported to CDC.
Since many people do not have symptoms, they don’t seek care from a
health provider and don’t get diagnosed with this infection. These cases
aren’t reported to public health authorities and aren’t counted in yearly
totals. CDC believes the actual number of acute hepatitis C cases in 2018 was
probably closer to 50,300.
How common is chronic hepatitis C in the United States?
In 2016, an estimated 2.4 million people were living with hepatitis C in the
United States.
Transmission / Exposure
How is hepatitis C spread?
The hepatitis C virus is usually spread when someone comes into contact
with blood from an infected person. This can happen through:
►Sharing drug-injection equipment.
Today, most people become infected with hepatitis C by sharing needles,
syringes, or any other equipment used to prepare and inject drugs.
►Birth.
Approximately 6% of infants born to infected mothers will get hepatitis C.
►Health care exposures.
Although uncommon, people can become infected when health-care
professionals do not follow the proper steps needed to prevent the spread of
bloodborne infections.
►Sex with an infected person.
While uncommon, hepatitis C can spread during sex, though it has been
reported more often among men who have sex with men.
►Unregulated tattoos or body piercings.
Hepatitis C can spread when getting tattoos or body piercings in unlicensed
facilities, informal settings, or with
non-sterile instruments.
►Sharing personal items.
People can get infected from sharing glucose monitors, razors, nail clippers,
toothbrushes, and other items that may have come into contact with infected
blood, even in amounts too small to see.
►Blood transfusions and organ transplants.
Before widespread screening of the blood supply in 1992, hepatitis C was
also spread through blood transfusions and organ transplants. Now, the risk
of transmission to recipients of blood or blood products is extremely low.
Hepatitis C is not spread by sharing eating utensils, breastfeeding, hugging,
kissing, holding hands, coughing, or sneezing. It is also not spread through
food or water.
Can you get hepatitis C more than once?
Yes. You can be infected again even if you have cleared the virus or were
successfully treated and cured. This is why people who currently inject and
share needles, syringes, or other drug preparation equipment, along with
those who receive maintenance hemodialysis, should be tested for hepatitis
C on a regular basis.
Can hepatitis C virus be spread through sexual contact?
Yes, but the risk of transmission from sexual contact is believed to be low.
The risk increases for men who have sex with men and for people who have
multiple sex partners, have a sexually transmitted disease, engage in rough
sex, or are infected with HIV.
Can you get hepatitis C by getting a tattoo or piercing?
Research has not shown that hepatitis C is spread within licensed,
commercial tattooing facilities. However, transmission of hepatitis C (and
other infectious diseases) is possible at facilities that don’t take the necessary
measures to control infections during tattooing or piercing. Unregulated
tattooing and piercing occurring in prisons and other informal settings may
put a person at risk of infection.
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.
Who is at risk for hepatitis C?
The following people are at increased risk for hepatitis C:
People who use injection drugs or did so in the past, even those who
injected only once many years ago
People with HIV infection
People with certain medical conditions, including those who ever
received maintenance hemodialysis and those with persistently
abnormal alanine aminotransferase (ALT) levels (an enzyme found
within liver cells).
People who have received transfusions or organ transplants, including
those who
o received clotting factor concentrates produced before 1987
o received a transfusion of blood or blood components before July
1992
o received an organ transplant before July 1992
o were notified that they received blood from a donor who later
tested positive for hepatitis C virus infection
Health care, emergency medical, and public safety personnel who have
been exposed to the blood of someone who has hepatitis C (through
needle sticks, sharps, or mucosal exposures)
Children born to mothers who have hepatitis C
Can a person be infected with both HIV and the hepatitis C virus?
Yes. A person can be “coinfected” with both HIV and the hepatitis C virus.
People who are coinfected are more likely to get cirrhosis as a result of their
chronic hepatitis C infection. To learn more about coinfection, read HIV and
Viral Hepatitis.
What is the risk of a pregnant woman passing hepatitis C to her baby?
Of every 100 infants born to mothers with hepatitis C, about six will become
infected with the hepatitis C virus. However, the risk is greater if the mother
has both HIV and hepatitis C.
Can women with hepatitis C breastfeed their babies?
Yes. There is no evidence that breastfeeding spreads hepatitis C, so infected
women can safely breastfeed their babies. However, women with cracked or
bleeding nipples should stop nursing temporarily until their nipples have
healed. Hepatitis C is spread through contact with blood, and not enough is
known about whether this practice is safe.
Can I get hepatitis C from a mosquito or other insect bite?
No. The hepatitis C virus has not been shown to be transmitted by
mosquitoes or other insects.
Can I donate blood if I have tested positive for hepatitis C?
The American Red Crossexternal icon does not accept blood donations from
anyone who has ever tested positive for hepatitis C or from anyone with
current signs or symptoms of hepatitis.
Can someone with hepatitis C donate organs?
According to the U.S. Department of Health & Human Service’s online
information on organ donation and transplantationexternal icon, very few
conditions would prevent someone from being an organ, eye, or tissue
donor. Even with acute or chronic hepatitis C, you may be able to donate
your organs or tissues. The transplant team will determine what organs or
tissue can be used based on a clinical evaluation, medical history, and other
factors.
Symptoms
What are the symptoms of acute (new) hepatitis C?
Many people newly infected with the hepatitis C virus don’t have symptoms,
don’t look or feel sick, and therefore don’t know they are infected. For people
who develop symptoms, they usually happen 2–12 weeks after exposure to
the hepatitis C virus and can include yellow skin or eyes, not wanting to eat,
upset stomach, throwing up, stomach pain, fever, dark urine, light-colored
stool, joint pain, and feeling tired.
What are the symptoms of chronic (long-term) hepatitis C?
Most people with chronic hepatitis C don’t have any symptoms or have only
general symptoms like chronic fatigue and depression. Many people
eventually develop chronic liver disease, which can range from mild to severe
and include cirrhosis (scarring of the liver) and liver cancer. Chronic liver
disease in people with hepatitis C usually happens slowly, without any signs
or symptoms, over several decades. Chronic hepatitis C virus infection is
often not recognized until people are screened for blood donation or from
an abnormal blood test found during a routine doctor’s visit.
Can a person spread hepatitis C without having symptoms?
Yes. If you are infected with the hepatitis C virus, you can spread it to others
even if you have no symptoms.
Tests
Who should get tested for hepatitis C?
CDC recommends hepatitis C testing for:
Are 18 years of age and older (get tested at least once in your lifetime)
Are pregnant (get tested during each pregnancy)
Currently inject drugs (get tested regularly)
Have ever injected drugs, even if it was just once or many years ago
Have HIV
Have abnormal liver tests or liver disease
Are on hemodialysis
Received donated blood or organs before July 1992
Received clotting factor concentrates before 1987
Have been exposed to blood from a person who has hepatitis C
Were born to a mother with hepatitis C
Should anyone be tested for hepatitis C more than once?
Yes. Regular testing is recommended for people who currently inject and
share needles, syringes, or other drug preparation equipment and for those
currently getting maintenance hemodialysis.
If I am pregnant, should I be tested for hepatitis C?
Yes, hepatitis C testing is recommended during every pregnancy.
What tests are used to diagnose someone with hepatitis C?
A blood test, called an HCV antibody test, is used to find out if someone has
ever been infected with the hepatitis C virus. This test, sometimes called the
anti-HCV test, looks for antibodies, which are proteins released into the
bloodstream when someone gets infected with the virus that causes
hepatitis C. People who have positive HCV antibody tests are given a follow-
up HCV RNA test to learn whether they have active infection.
When should I expect to get my test results?
Test results can take anywhere from a few days to a few weeks to come back.
Rapid anti-HCV tests are available in some health clinics, and the results of
these tests are available in 20–30 minutes.
How are hepatitis C test results interpreted?
Your doctor will help interpret the results from your HCV antibody test and
help guide you through next steps. The test can be “non-reactive,” or
“negative,” meaning that you are not currently infected with the hepatitis C
virus. The test can also be “reactive,” or “positive,” which means you have
been infected with the hepatitis C virus at some point in time. It is important
to know that
Once you have been infected, you will always have antibodies in your
blood. This is true if you have cleared the virus, have been cured, or
still have the virus in your blood.
A reactive, or positive, antibody test does not necessarily mean that
you currently have hepatitis C, so a follow-up test is needed.
What should I do if the HCV antibody test is reactive?
If the antibody test is reactive or positive, you need an additional test
to see if you currently have hepatitis C. This test is called a nucleic acid
test (NAT) for HCV RNA, but it can also be called a PCR test.
If the nucleic acid test for HCV RNA (or PCR test) is:
o Negative – this means you were infected with hepatitis C virus,
but the virus is no longer in your body because you were cured
or cleared the virus naturally.
o Positive – this means you currently have the virus in your blood
and are infectious, meaning you can spread the virus to others.
If you have a reactive antibody test and a positive NAT for HCV RNA,
you need to talk to a doctor about treatment. Treatments are available
that can cure most people with hepatitis C in 8–12 weeks.
How soon after exposure to the hepatitis C virus can a test tell if someone is
infected?
After exposure to the hepatitis C virus, it can take 8–11 weeks for an HCV
antibody test to be positive. For most people who are infected, the anti-HCV
blood test will become positive by 6 months after exposure. A special kind of
blood test called a nucleic acid test (NAT) that detects HCV RNA (also called a
PCR test) can tell if a person is infected within 1–2 weeks of exposure.
Can a person have normal liver enzyme level and still have hepatitis C?
Yes. For people with hepatitis C, it is common for liver enzyme levels to go up
and down, sometimes returning to normal or near normal. Some people with
hepatitis C have liver enzyme levels that are normal for over a year even
though they have chronic liver disease.
Treatment
What is the treatment for hepatitis C?
Treatment is recommended for all people, including non-pregnant women,
with acute or chronic hepatitis C (including children aged ≥3 years and
adolescents). Current treatments usually involve just 8–12 weeks of oral
therapy (pills) and cure over 90% with few side effects. The FDA has a list
of currently approved FDA treatments for hepatitis C.external icon
What can people with chronic hepatitis C do to protect the liver?
People with chronic hepatitis C and those with cirrhosis (even if they have
been cured of their hepatitis C infection) should be monitored regularly by a
doctor, because these people have a continued risk of complications of
advanced liver disease, including liver cancer. In addition, people living with
hepatitis C should
be vaccinated against hepatitis A and hepatitis B
avoid alcohol because it can cause additional damage to the liver
check with their doctor before taking any prescription pills, herbs,
supplements, or over-the-counter medications, as these can potentially
damage the liver
be tested for HIV, because people who have both infections are more
likely to get cirrhosis
Prevention
Is there a vaccine that can prevent hepatitis C?
No. Currently, there is no vaccine to prevent hepatitis C.
Hepatitis C and Employment
Should a person infected with the hepatitis C virus be restricted from working in
certain jobs or settings?
CDC’s recommendations for prevention and control of the hepatitis C virus
infection state that people should not be excluded from work, school, play,
child care, or other settings because they have hepatitis C virus infection.
There is no evidence that people can get hepatitis C from food handlers,
teachers, or other service providers without blood-to-blood contact.
