How Does Hepatitis C Spread

How Is Hepatitis C Transmitted

How is Hepatitis C spread? — Mayo Clinic

Because HCV is primarily spread through contact with infected blood, people who inject drugs are at increased risk for HCV infection. HCV can also be transmitted from an infected mother to child at the time of birth, from unregulated tattoos or body piercings, and from sharing personal items that may be contaminated with infected blood, even in amounts too small to see. Much less often, HCV transmission occurs through sexual contact with an HCV-infected partner, especially among people with multiple sex partners and men who have sex with men. Currently in the United States, health care related transmission of HCV is rare, but people can become infected from accidental needle sticks and from breaches in infection control practices in health care facilities.

Encouraging Others To Get Tested For Hepatitis C

While the odds of passing on the hepatitis C virus are low, you should still tell anyone at risk that you have hepatitis C. You should tell sexual partners, spouses, and family members. Your infection may be difficult to discuss, but anyone at potential risk must know. That way, they can get tested and treated if needed. Read more on why you should get tested for hepatitis C.

Common Symptoms Of Hepatitis C

Hepatitis C symptoms can show up between 2 and 12 weeks after being exposed to the virus. In many cases, though, there are no symptoms at allâuntil the infection causes serious health complications. Itâs possible for people to have HCV for many years and not know it due to the absence of symptoms.

When hepatitis C symptoms do occur, they may include:

  • Joint pain
  • Pain in the upper right part of the stomach
  • Jaundice
  • Nausea

Who Is At Risk For Hepatitis B

Although unprotected sex is the most common way of becoming infected with hepatitis B, infection is more likely for people who have multiple sex partners. Shared needles also are an important means of spreading hepatitis B. Other risk factors are being a health care worker, but infection usually is related to needle sticks. There also is a risk of becoming infected by living with someone who has chronic hepatitis B, in part due to sexual transmission.

What Medications Cure Hepatitis C Infection

How Hepatitis C is Spread: Understanding Transmission

    Interferons, for example, Roferon-A and Infergen, and pegylated interferons such as Peg-IntronT, Pegasys, were mainstays of treatment for years. Interferons produced sustained viral response of up to 15%. Later, peglatedll forms produced SVR of 50%-80%. These drugs were injected, had many adverse effects, required frequent monitoring, and were often combined with oral ribavirin, which caused anemia. Treatment durations ranged up to 48 weeks.

    Direct-acting anti-viral agents are antiviral drugs that act directly on hepatitis C multiplication.

    What Are The Complications Of Undiagnosed Hepatitis C

    • Hepatitis C is known to be associated with two skin conditions, lichen planus and porphyria cutanea tarda.
    • Diabetes, heart disease, and arterial blockage are more common among patients with chronic hepatitis C infection than in the general population. It may be that liver damage and chronic inflammation caused by hepatitis C may affect the levels of blood fats and blood sugar.
    • Low platelet counts may occur as a result of the destruction of platelets by antibodies.

    Common Symptoms Of Hepatitis

    If you are living with a chronic form of hepatitis, like hepatitis B and C, you may not show symptoms until the damage affects liver function. By contrast, people with acute hepatitis may present with symptoms shortly after contracting a hepatitis virus.

    Common symptoms of infectious hepatitis include:

    It is crucial to understand what is causing hepatitis in order to treat it correctly. Doctors will progress through a series of tests to accurately diagnose your condition.

    Hepatitis C And Blood Spills

    When cleaning and removing blood spills, use standard infection control precautions at all times:

    • Cover any cuts or wounds with a waterproof dressing.
    • Wear single-use gloves and use paper towel to mop up blood spills.
    • Clean the area with warm water and detergent, then rinse and dry.
    • Place used gloves and paper towels into a plastic bag, then seal and dispose of them in a rubbish bin.
    • Wash your hands in warm, soapy water then dry them thoroughly.
    • Put bloodstained tissues, sanitary towels or dressings in a plastic bag before throwing them away.

    Treatments For Hepatitis C

    Hepatitis C Spreads Through TN Prisons

    Hepatitis C can be treated with medicines that stop the virus multiplying inside the body. These usually need to be taken for several weeks.

    Until recently, most people would have taken 2 main medicines called pegylated interferon and ribavirin .

    Tablet-only treatments are now available.

    These new hepatitis C medicines have been found to make treatment more effective, are easier to tolerate, and have shorter treatment courses.

    They include sofosbuvir and daclatasvir.

    Using the latest medications, more than 90% of people with hepatitis C may be cured.

    But it’s important to be aware that you will not be immune to the infection and should take steps to reduce your risk of becoming infected again.

    What Are The Signs & Symptoms Of Hcv Infection

    Hepatitis C can be a “silent but deadly” infection. Most people with HCV have no symptoms. But even without symptoms, they can develop health problems decades later and can still pass the disease to others.

    When symptoms do happen , they can be similar to those of hepatitis A and hepatitis B and include:

    • jaundice
    • fever
    • nausea, vomiting, and lack of appetite
    • belly pain
    • joint pain

    Hepatitis B: What Happens

    Many adults who get hepatitis B have mild symptoms for a short time and then get better on their own. But some people are not able to clear the virus from the body, which causes a long-term infection. Nearly 90% of infants who get the virus will carry it for life. Over time, hepatitis B can lead to serious problems, such as liver damage, liver failure, and liver cancer.

    What Are The Treatment Guidelines For Hepatitis C

    Hepatitis C treatment is best discussed with a doctor or specialist familiar with current and developing options as this field is changing, and even major guidelines may become outdated quickly.

    The latest treatment guidelines by the American Association for the Study of Liver Disease and Infectious Disease Society of America recommends use of DAAs as first-line treatment for hepatitis C infection. The choice of DAA varies by specific virus genotype, and the presence or absence of cirrhosis. In the U.S., specific insurance providers also might influence the choice due to the high cost of DAAs. Although the individual, public health, and cost benefits of treating all patients with hepatitis C is clear, the most difficult barrier to treating all people with HCV is the very high cost of the drug regimens. Patients are encouraged to discuss options with their health care professional.

    Treatment is recommended in all patients with chronic hepatitis C unless they have a short life expectancy that is not related to liver disease. Severe life-threatening liver disease may require liver transplantation. Newer therapies with DAAs have allowed more and more patients to be treated.

    What are the goals of therapy for hepatitis C infection?

    The ultimate goals of antiviral therapy are to

    • prevent transmission of hepatitis C,
    • prevent progression to cirrhosis and liver cancer, and
    • improve survival and quality of life.

    Recommendation For Test Of Cure

    Symptoms and warning signs of Hepatitis C
    • Not relevant for these infections.

    • Patients with newly diagnosed infection caused by HBV or HCV should have serological markers of infection measured 3 and 6months later to establish whether the infection has become chronic,,, .

    • Serological follow up after antiviral therapy is beyond the scope of this guideline.

    How Can I Prevent Spreading Hepatitis B To Others

    If you have hepatitis B, follow the steps above to avoid spreading the infection. Your sex partners should get a hepatitis B test and, if they arent infected, get the hepatitis B vaccine. You can protect others from getting infected by telling your doctor, dentist, and other health care professionals that you have hepatitis B. Dont donate blood or blood products, semen, organs, or tissue.

    How Does Hepatitis C Spread

    Hepatitis C is a blood-borne virus, meaning that a person must come into contact with blood that contains the virus to contract it.

    Most new cases of hepatitis C in the U.S. are due to injecting recreational drugs. Transmission can happen when a person with the virus shares needles or contaminated drugs with others.

    The hepatitis C virus is very difficult to kill, and even tiny spots of blood that are invisible to the human eye can contain the virus.

    People can also contract the virus in healthcare settings through exposure to blood that contains the virus, such as through accidental needlesticks.

    According to the , the most common ways for hepatitis C to spread include:

    • using injectable drugs
    • receiving a blood transfusion or organ transplant before 1992, which is before regular blood screens took place
    • being accidentally poked with a used syringe, which can occur in healthcare settings
    • being born to a mother who has hepatitis C

    Hepatitis C can also spread through the following actions, though these are less common:

    • engaging in sexual contact without using barrier protection, especially contact that may involve blood, such as rough or anal sex
    • sharing personal items that may contain blood, such as toothbrushes or razors
    • getting a tattoo or piercing from an unregulated provider

    Hepatitis C often has no symptoms. This means that a person can contract hepatitis C without knowing it. This makes it easier for them to transmit it to others.

    Chronic Hepatitis C Treatment

    Treatment of chronic hepatitis C has evolved, rendering many earlier drugs obsolete. The drugs currently used include pegylated interferon, ribavirin, elbasvir, grazoprevir, ledipasvir, sofosbuvir, paritaprevir, ritonavir, ombitasvir, dasabuvir, simeprevir, daclatasvir. These are always used in various combinations, never alone. Interferon is given by injection while the other medications are pills. Studies have shown that combinations of these drugs can cure all but a small proportion of patients however, serious side effects of treatment can occur.

    Treatment options need to be discussed with a knowledgeable physician, as the appropriate combination is dependent upon multiple factors. These include genotype , prior treatment and results, drug intolerances, presence of compensated liver disease or uncompensated cirrhosis, presence of HIV co-infection, other complicating conditions and liver transplantation.

    Hepatitis C And Health

    How The Hepatitis C Virus Is Spread

    How can health-care personnel avoid exposure to HCV?

    Avoiding occupational exposure to blood is the primary way to prevent transmission of bloodborne illnesses among health-care personnel. To promote blood safety in the workplace, health-care personnel should consult infectious-disease control guidance from the National Institute for Occupational Safety and Health and from CDC. Depending on the medical procedure involved, Standard Precautions may include the appropriate use of personal protective equipment .

    What is the risk of acquiring hepatitis C after being accidentally exposed to HCV-contaminated blood or body fluids in the workplace?

    Although sharps injuries have decreased in recent decades due to improved prevention measures, they continue to occur, placing health-care personnel at risk for several bloodborne pathogens like hepatitis C. A recent analysis of several studies revealed an overall 0.2% risk for infection among those exposed to HCV-antibody-positive blood through needlestick or sharps injuries . Updated guidelines for management and treatment of hepatitis Cexternal icon are available to provide guidance for health-care personnel who become infected via exposure to contaminated blood at the workplace.

    Other than needlesticks, do other exposures place health-care personnel at risk for hepatitis C?

    What Are The Treatments For Hepatitis C

    Treatment for hepatitis C is with antiviral medicines. They can cure the disease in most cases.

    If you have acute hepatitis C, your health care provider may wait to see if your infection becomes chronic before starting treatment.

    If your hepatitis C causes cirrhosis, you should see a doctor who specializes in liver diseases. Treatments for health problems related to cirrhosis include medicines, surgery, and other medical procedures. If your hepatitis C leads to liver failure or liver cancer, you may need a liver transplant.

    Preparation And Use Of Drugs

    Washing hands and using sterile water to prepare and use drugs lower the risk of catching hepatitis A. The use of new paraphernalia for the preparation, injection and inhalation of drugs lowers the risk of catching hepatitis B and C through blood.

    Never share drug paraphernalia. To know the location of distribution points for drug injecting material, call Info-Santé 811.

    Can Hepatitis C Be Prevented

    There is no vaccine for hepatitis C. But you can help protect yourself from hepatitis C infection by:

    • Not sharing drug needles or other drug materials
    • Wearing gloves if you have to touch another person’s blood or open sores
    • Making sure your tattoo artist or body piercer uses sterile tools and unopened ink
    • Not sharing personal items such toothbrushes, razors, or nail clippers
    • Using a latex condom during sex. If your or your partner is allergic to latex, you can use polyurethane condoms.

    Hepatitis C: How Does It Spread

    How is hepatitis C transmitted?

    It spreads through infected blood. In the U.S., sharing needles or other items used to inject drugs is the most common cause of infection. Getting a tattoo or body piercing with an infected needle is another means of exposure. A mother may pass the virus to their child at birth. In rare cases, unprotected sex spreads hepatitis C, but the risk appears small. Having multiple sex partners, HIV, or rough sex seems to raise risk for spreading hepatitis C.

    How Is Hepatitis Diagnosed

    Chronic hepatitis can quietly attack the liver for years without causing any symptoms. Unless the infection is diagnosed, monitored, and treated, many of these people will eventually have serious liver damage. Fortunately, blood tests can determine whether you have viral hepatitis, and if so, which kind.

    Is Hepatitis Testing Recommended For People With Hiv

    Yes. Everyone living with HIV should be tested for HBV and HCV when they are first diagnosed with HIV and begin treatment. People living with HIV who have ongoing risk factors for getting hepatitis B or hepatitis C should be tested annually.

    In addition, new HCV screening recommendations from the Centers for Disease Control and Prevention call for:

    • One-time screening for all adults 18 years and older
    • Screening of all pregnant women during every pregnancy
    • Testing for all persons with risk factors, with testing continued periodic testing those with ongoing risk.
    • People can be sick for a few weeks to a few months
    • Most recover with no lasting liver damage
    • Although very rare, death can occur
    • 15%25% of chronically infected people develop chronic liver disease, including cirrhosis, liver failure, or liver cancer
    • More than 50% of people who get infected with the hepatitis C virus develop a chronic infection
    • 5%-25% of people with chronic hepatitis C develop cirrhosis over 1020 years

    What Do Hepatitis C Symptoms Look Like

    Hepatitis C infection can go through two stages: acute and chronic. In the early, or acute stage, most people don’t have symptoms. If they do develop symptoms, these can include:

    • flu-like symptoms, tiredness, high temperature and aches and pains
    • loss of appetite
    • tummy pain
    • jaundice, meaning your skin and the whites of your eyes turn yellow

    While for some people, the infection will clear without treatment, in most cases, acute infection will develop into long-term chronic infection. Chronic infection may not become apparent for a number of years until the liver displays signs of damage. These symptoms can include:

    • mental confusion and depression these are specific to hepatitis C
    • constantly feeling tired
    • nausea, vomiting or tummy pain
    • dark urine
    • feeling bloated
    • joint and muscle pain

    Without treatment, chronic hepatitis C can cause scarring of the liver , which can cause the liver to stop working properly. A small number of people with cirrhosis develop liver cancer and these complications can lead to death. Other than a liver transplant, theres no cure for cirrhosis. However, treatments can help relieve some of the symptoms.

    Effective Treatments Are Available For Hepatitis C

    Hepatitis A: How is it spread?

    New medication to treat for HCV have been approved in recent years. These treatments are much better than the previously available treatment because they have few side effects and do not need to be injected. There are several direct-acting antiviral HCV treatments that cure more than 95% of people who take them in 8 to 12 weeks. HCV treatment dramatically reduces deaths among people with HCV infection, and people who are cured of HCV are much less likely to develop cirrhosis or liver cancer.
