Ways To Contract Hepatitis C

Tests To Diagnose Hepatitis C

How Do You Catch Hepatitis C?

How is Hepatitis C diagnosed?

There are two main blood tests typically used to diagnose Hepatitis C. First, youll have a screening test that shows if youve ever had Hepatitis C at some point in your life. If this test is positive, youll have a second test to see if you have Hepatitis C now. These blood tests are described below:

Hepatitis C antibody test

This is the screening test used by doctors to show whether or not you have ever been exposed to Hepatitis C at some time in your life, by detecting antibodies in your blood. Antibodies are substances your body makes to fight off all kinds of infections. If you were ever infected with Hepatitis C, your body would have made antibodies to fight the virus.

If the test result is:

  • Negative, it means you have not been exposed to Hepatitis C and further testing is usually not needed.
  • Positive, you have had Hepatitis C at some point. However, it does not tell you whether you have it now. Youll need to see your doctor for another test the Hepatitis C RNA test to determine if the virus is still active and present in your blood.

Hepatitis C RNA Qualitative Test

This test will determine whether or not you are currently infected with Hepatitis C. It is often called the PCR test because of the process used . It looks for the genetic material of the Hepatitis C virus in your blood.

How To Prevent Hepatitis B

Hepatitis B is a liver infection caused by a virus . It can be serious and theres no cure, but the good news is its easy to prevent. You can protect yourself by getting the hepatitis B vaccine and having safer sex. If you have oral, anal, and vaginal sex, use condoms and dental dams to help stop the spread of hepatitis B and other STDs.

What Medications Cure Hepatitis C Infection

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.

How Is Hepatitis C Transmitted

The way the virus does spread is through contact with the blood of someone who is infected. Most commonly, this occurs through one of the following methods.

Intravenous drug usePeople who share needles or other supplies while injecting drugs like cocaine and heroin have a high risk for contracting hepatitis C. Even if you only used these types of drugs once years ago, there is still a chance you are infected.

Needlestick injuriesHealth care or other safety workers may come into contact with an infected persons blood if theyre accidentally stuck with a contaminated needle or other sharp object. Parents often worry about their children developing hepatitis C after finding a needle on the ground or at the beach. While thats possible, its unlikely, Dr. Nachman saysthe most commonly discarded needles are insulin needles, which typically dont contain enough blood to transmit hepatitis C. Plus, the virus can only survive about a day outside of the body.

Medical proceduresNow, donated blood and organs are screened for the hepatitis C virus. However, before 1992, that wasnt the case, so people who received blood transfusions or an organ transplant before that time might have become infected.

Tattoos and piercingsThese days, licensed and regulated tattoo parlors dont pose much of a danger. However, piercings or tattoos received in unregulated settings, such as prisons, may spread hepatitis C, Dr. Kodali says.

Activities That Can Pass Hepatitis C

Hepatitis C Basics: For People Who Use Drugs by Harm ...
  • Sharing personal care items: Shared razors, toothbrushes, nail clippers and other household items that might have infected blood on them can pass hepatitis C.
  • Condomless sex: In general, sexual transmission of hepatitis C is not common. The risk increases when certain factors are present, such as condomless anal sex, HIV, sexually transmitted infections, sex where blood is present, group sex and chemsex . Thus, the risk of transmission may be higher among some groups of men who have sex with men .
  • Transmission from a parent to child during pregnancy or childbirth : The risk of perinatal transmission is about 5%.
  • Needlestick injuries: An injury caused by a needle that punctures the skin can pass hepatitis C because of the possibility of exposure to hepatitis C from contact with blood in the needle or syringe.

Blood tests for hepatitis C

There are several blood tests for the diagnosis of hepatitis C infection. Blood can be tested for antibody to hepatitis C . It takes about 8-12 weeks on average, and up to 6 months, for antibodies to develop after the initial infection with hepatitis C, so screening for antibodies may miss a few newly infected individuals. Having antibodies is not an absolute indication of active, multiplying hepatitis C virus, but if the antibody test is positive , the statistical probability of active infection is greater than 99%.

Several tests are available to measure the amount of hepatitis C virus in a person’s blood . The hepatitis C virus’s RNA can be identified by a type of test called polymerase chain reaction that detects circulating virus in the blood as early as 2-3 weeks after infection, so it can be used to detect suspected acute infection with hepatitis C early infection. It also is used to determine whether active hepatitis is present in someone who has antibodies to hepatitis C, and to follow the viral load during treatment.

Blood tests are also performed to identify the genotypes of HCV. Genotypes respond differently to different treatment, so this information is important in selection of the most appropriate treatment regimen.

Estimation of liver fibrosis using blood tests also is quite reliable in diagnosing clinically significant scarring these include FIB-4, FibroSure, Fibrotest, and aspartate aminotransferase-to-platelet ratio index .

How To Prevent Hepatitis C

There is currently no vaccine for hepatitis C. Avoiding contact with infected blood is the only way to prevent the condition.

The most common way for people to contract hepatitis C is by injecting street drugs. Because of this, the best way to prevent hepatitis C is to avoid injecting.

Treatments can help many people quit. People in the U.S. can call the National Helpline for help with finding treatments.

If a person finds it difficult to stop, they can reduce the risk of contracting hepatitis C by never sharing drug equipment, ensuring a clean, hygienic environment, and always using new equipment, including syringes, ties, alcohol swabs, cottons, and cookers.

People who may come into contact with infected blood, such as healthcare workers and caretakers, should always wash the hands thoroughly with soap and water after any contact, or suspected contact, with blood. They should also wear gloves when touching another persons blood or open wounds.

People can also reduce their risk by making sure that any tattoo artist or body piercer they visit uses fresh, sterile needles and unopened ink.

The risk of contracting hepatitis C through sexual contact is low. Using barrier protection, such as condoms, reduces the risk of most sexually transmitted infections.

People who have hepatitis C can reduce the risk of transmitting it to others by:

There are many misconceptions about how hepatitis C spreads. People cannot transmit or contract the virus through:

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

Why Getting Tested Is Important

A blood test is one of the only ways to confirm a diagnosis of hepatitis C. Additionally, hepatitis C often has no visible symptoms for many years.

Because of this, its important to be tested if you believe youve been exposed to the virus. Getting a timely diagnosis can help ensure you receive treatment before permanent liver damage occurs.

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.

What Is Hepatitis C Infection How Many People Are Infected

Hepatitis C virus infection is an infection of the liver caused by the hepatitis C virus . It is difficult for the human immune system to eliminate hepatitis C from the body, and infection with hepatitis C usually becomes chronic. Over decades, chronic infection with hepatitis C damages the liver and can cause liver failure. In the U.S., the CDC has estimated that approximately 41,200 new cases of hepatitis C occurred in 2016. When the virus first enters the body there usually are no symptoms, so this number is an estimate. About 75%-85% of newly infected people become chronically infected. In the U.S., more than 2 million people are estimated to be chronically infected with hepatitis C. Infection is most commonly detected among people who are 40 to 60 years of age, reflecting the high rates of infection in the 1970s and 1980s. There are 8,000 to 10,000 deaths each year in the U.S. related to hepatitis C infection. HCV infection is the leading cause of liver transplantation in the U.S. and is a risk factor for liver cancer. In 2016, 18,153 death certificates listed HCV as a contributing cause of death this is believed to be an underestimate.

Those who have cirrhosis from HCV also have a yearly risk of liver cancer of about 1%-5%.

Activities That Do Not Spread Hepatitis C

Because HCV is spread through blood, you cannot get the virus from:

  • Breast milk
  • Food or water
  • Casual contact with an HCV-infected person, such as hugging, holding hands, or kissing
  • Being coughed or sneezed on
  • Sharing food, drinks, or eating utensils
  • Via mosquitoes or other insects

Is Screening For Hepatitis C Recommended During Pregnancy

World Hepatitis Day: Finding the Missing Millions

There is a 4%-7% risk of transmitting HCV from mother to infant with each pregnancy. Currently, there is no CDC recommendation for routine hepatitis C screening during pregnancy, and there is no currently recommended medicine to prevent transmission from mother to infant . However, CDC is monitoring research findings and may make recommendations in the future as evidence arises.

While data is still limited, a recent study of over 1,000 cases in the United Kingdom found that 11% of infants had been infected at birth, and that these infants were likely to develop cirrhosis in their early 30s. The case for screening for HCV during pregnancy includes the potential to safely treat mothers during pregnancy with direct-acting antiviral agents to treat the mother before cirrhosis develops, prevent infant transmission, and prevent transmission to others. Children born to HCV-infected mothers may also be offered treatment at an early age to prevent cirrhosis, as well as transmission to others. Coordination of care between multiple specialists will be important to accomplish these goals.

Children of HCV-infected mothers may be screened for hepatitis C as early as 1-2 months of age using hepatitis C viral load or PCR testing . Antibodies to hepatitis C passed from the mother to child will be present for up to 18 months, so children should be tested for HCV antibody no earlier than this.

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.

How Is Hepatitis C Infection Prevented

Unfortunately, there is no vaccine to prevent hepatitis C. To reduce your risk of getting hepatitis C:

  • Injection drug use is the most common way people get hepatitis C. Avoid injecting drugs to reduce your risk. If you do inject drugs, use sterile injection equipment. Avoid reusing or sharing.
  • Avoid sharing personal care items that might have blood on them
  • If you are a health care or public safety worker, follow universal blood/body fluid precautions and safely handle needles and other sharps
  • Consider the risks if you are thinking about tattooing, body piercing, or acupuncture are the instruments properly sterilized?
  • If youre having sex with more than one partner, use latex condoms correctly and every time to prevent the spread of sexually transmitted diseases, including hepatitis C.

How Can I Avoid And Stay Safe From Hepatitis A

Despite the severity of HAV, most people recover fully with a lifelong immunity.

Additionally, there are precautionary measures you can take to stay out of harm.

Clean drinking water and knowledge of food safety are the simplest way to minimize risk.

Washing your hands frequently and being vaccinated are also noted to be effective measures.

Hepatitis A vaccines were recommended in the U.S. starting in 1996. Since then, there has been a steady decrease in reported cases. In 1996 approximately 31,000 cases were reported in the U.S. and that number has plummeted to an average under 1,500. Although, recent outbreaks in various parts of the U.S. have led to a surprising and even record-setting return of hepatitis A.

It is recommended that each person be injected with two doses of the vaccine for long-lasting protection. Each dose should be taken at least six months apart.

It is also important to avoid taking an unnecessary medication. For example, medication that helps with vomiting should not be taken.

The vaccine has been proven as a legitimate force against HAV. Nearly 100 percent of people develop protective counteracting agents to the virus within one month after injection. Much of the reason for vaccine success is because HAV is an acute illness. Once a person has contracted hepatitis A, they cant get it again.

It is incredibly important to be vaccinated for HAV.

Unlike hepatitis B and C, HAV does not cause chronic liver disease. But, the virus can still be fatal.

HCV is more common in adults than in children. Rates of HCV infection in the United States almost tripled from 2010 to 2015, according to the Centers for Disease Control and Prevention . Most of these new infections are in young people who inject drugs many of whom moved from abusing prescription pain relievers to injecting heroin, which often is cheaper and easier to get.

Because women of reproductive age are part of this group, experts worry that more newborns will be at risk for HCV.

Articles On Hepatitis C

If you’ve just been diagnosed with hepatitis C, you may wonder how you got it and worry about passing on the virus to a loved one. If you’ve had the disease for a long time without knowing it, you could dwell on every little incident in the past where you might have accidentally exposed a family member to the disease.

It’s important to remember that hepatitis C isn’t easy to catch. If you take a few precautions, it’s almost impossible to pass on the disease to someone else.
