How Is Hepatitis C And B Transmitted

Is There A Hepatitis C Vaccine

How Is Hepatitis Transmitted?

No vaccine exists for hepatitis C right now. While efforts to develop a vaccine for this specific strain are ongoing, it’s proven challenging. That’s because hepatitis C tends to avoid immune responses. In other words, a person can catch hepatitis C repeatedly despite past infection, which is what makes it hard to create a vaccine that works for this virus.

There is an effective treatment for hepatitis C, though, and it involves direct-acting antivirals . Thanks to this treatment, WHO aims to cut 80% of hepatitis C cases worldwide by 2030. Researchers across the globe think that a vaccine is needed to accomplish this goal, so creating one is a high priority.

Who Announces The Update Of Hcv Guidelines On Testing And Treatment

WHO has made available the membership of the Guidelines Development Group for key updates of the 2018 WHO Guidelines for the Care and Treatment of persons diagnosed with chronic hepatitis C virus infection” and the 2017 WHO guidelines on hepatitis B and C testing. This guideline update will be included in the planned 2022 Consolidated Guidelines on Hepatitis prevention, diagnosis, treatment and carewhich will incorporate both existing and new recommendations relating to chronic hepatitis B and C virus infection.

The GDG group will meet virtually on the 18-21 October 2021 across seven sessions.

The main objectives of this HCV update are:

  • to update key recommendations in HCV service delivery
  • HCV diagnostics and
  • treatment for hepatitis C infected adolescents and children .

This represents Part 1 and Part 2 of planned updated HCV guidelines recommendations. Part 3 HCV guidelines update on HCV self-testing guidance was completed in July 2021. Part 4 update to HBV guidelines updates will take place in early 2022.

The new 2022 WHO “Consolidated guidelines for prevention, testing, care and treatment of viral hepatitis B and C” will incorporate existing and updated guidelines recommendations.

In line with WHO policy on conflict of interest, members of the public and interested organizations can access the biographies of the GDG members and inform WHO of their views about them. All comments should be sent by email to by 14 October 2021.

Hepatitis C Symptoms & Treatment

FAST FACTS:

  • Hepatitis C is found in infected blood. It is also rarely found in semen and vaginal fluids.

  • Hepatitis C is mainly passed on through using contaminated needles and syringes or sharing other items with infected blood on them. It can also be passed on through unprotected sex, especially when blood is present.

  • You can prevent hepatitis C by never sharing needles and syringes, practising safer sex, and avoiding unlicensed tattoo parlours and acupuncturists.

  • Hepatitis C will often not have any noticeable symptoms, but a simple blood test carried out by a healthcare professional will show whether you have hepatitis C.

  • In the early stages, some peoples bodies can clear a hepatitis C infection on their own, others may develop chronic hepatitis C and will need to take antiviral treatment to cure the infection.

  • Without treatment, chronic hepatitis C can lead to permanent liver damage.

Hepatitis C is part of a group of hepatitis viruses that attack the liver.

Its mainly passed on through contaminated needles, either from injecting drugs or from needle stick injuries in healthcare settings. It can also be transmitted sexually, especially during anal sex or other types of sex that may involve blood.

Some groups are more at risk of getting hepatitis C than others, including people who use drugs, people in prisons, men who have sex with men, health workers and people living with HIV.

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:

How Do People Get Hepatitis C

Preventing Hepatitis B

Hepatitis C virus is found in the blood of people with HCV infection. It enters the body through blood-to-blood contact.

Until reliable blood tests for HCV were developed , people usually got hepatitis C from blood products and blood transfusions. Now that blood and blood products are tested for HCV, this is no longer the typical means of infection.

Currently, people usually get hepatitis C by sharing needles for injection drug use. An HCV-infected woman can pass the infection to her baby during birth. It is also possible to get hepatitis C from an infected person through sexual contact, an accidental needlestick with a contaminated needle, or improperly sterilized medical, acupuncture, piercing, or tattooing equipment.

What Are The Symptoms Of Hepatitis B And C

In most patients, hepatitis B develops slowly over the course of several decades, and thus most patients have no symptoms. People who have advanced liver disease such as cirrhosis of the liver may experience complications and symptoms that reflect liver failure. Other symptoms include:

  • A buildup of fluid within the abdominal cavity
  • Confusion and tremors , which are complications due to the inability of the liver to filter out toxins that are normally cleaned out by a healthy liver
  • Vomiting of blood, or blood within the stool . This is a complication in which enlarged veins within the esophagus or stomach bleed as a consequence of increased pressure around the diseased liver.

Most patients with chronic hepatitis C infection report no symptoms. But some patients may have very nonspecific symptoms related to fatigue and discomfort on the right side of the abdomen. Often, symptoms that lead to a diagnosis of hepatitis C are noticeable only at the end stage of liver disease, when the patient has developed liver cirrhosis and liver failure.

Because hepatitis B and C typically have no specific symptoms, many people who have the viruses dont even know it.

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.

Testing Treating And Reducing Risk Of Hepatitis

If you think youre at risk for hepatitis infection, talk to your healthcare provider about getting tested. A blood test is usually done to see if you have been exposed to the virus. Women who are pregnant or trying to become pregnant should get tested for hepatitis.

Get treated for hepatitis infection

There are treatments for hepatitis. Treating long-lasting hepatitis B or C infection can reduce the amount of the virus in a person, which may lower the risk of liver cancer.

How To Prevent Transmission

How is Hepatitis B & C transmitted? | Apollo Hospitals

Between 2% and 6% of adults infected with hepatitis B virus will develop chronic hepatitis B. Chronic hepatitis B can lead to liver failure and liver cancer, so protecting yourself is important.

The hepatitis B vaccine is safe for almost everyone and about 95% effective for providing long-term protection against hepatitis B infection.

While anyone can benefit from the vaccine, people who are at a greater risk of being exposed to the virus because of their work, lifestyle or medical history are strongly encouraged to be immunized. In many countries, babies born to infected mothers get vaccinated at birth. All babies born in the United States are routinely vaccinated.

Hepatitis B immune globulin , is another way to prevent hepatitis B infection in babies born to infected mothers or after exposure to the virus. This uses concentrated antibodies to provide immediate protection. According to the Centers for Disease Control and Prevention, it is given as a shot and can provide short-term protection against hepatitis B.

Because the hepatitis B vaccine does not protect against HIV, hepatitis C or other diseases spread through sex and contact with blood, it’s still important to keep using basic protective strategies. Practicing safer sex and not sharing needles are recommended even if you’re immune to hepatitis B.

Sexual Transmission And Hepatitis C

Although not common, hepatitis C can be transmitted through sexual activity. Having a sexually transmitted infection, having sex with multiple partners, and engaging in anal sex appear to increase a persons risk for hepatitis C. MSM with multiple sex partners who are coinfected with HCV and HIV have been shown to transmit hepatitis C. There is no vaccine for hepatitis C. The best way to prevent hepatitis C is by avoiding behaviors that can spread the disease, especially sharing needles or other equipment to inject drugs. CDC recommends one-time hepatitis C testing of all adults and regular testing for people with risk factors. The American Association for the Study of Liver Disease and the Infectious Diseases Society of America also recommend that people who are infected with HCV be provided with curative, direct-acting antiviral medicationsexternal icon to treat their HCV infection.

Are Hepatitis B And C Preventable

Hepatitis C Information, Virus Structure, Spread, Symptoms ...

Hepatitis B is a vaccine-preventable disease.

There is a three-shot vaccination series that is very effective in protecting people against the virus if theyre exposed. In the United States, all newborns are vaccinated for hepatitis B and all pregnant women are screened for hepatitis B during pregnancy. This way, mothers infected with hepatitis B can take protective steps to decrease the risk of transmission of the virus to the child.

There is no vaccine for hepatitis C.

What If You Test Positive

If a test says you have viral hepatitis, you can take steps to protect the ones you love. For hepatitis A, wash hands frequently. For hepatitis B and C, avoid sharing nail clippers, razors, or toothbrushes. Hepatitis B, and sometimes hepatitis C, can be passed through sexual contact. Make sure everyone in your household gets the hepatitis B vaccine. An important step is to see a specialist to discuss treatment options.

How Do You Treat Hepatitis C

Modes of transmission for Hepatitis B virus – Dr. Ramakrishna Prasad

People with acute infection do not always need treatment, because their immune system may clear hepatitis C on its own. If you test positive during the acute stage, your doctor may ask you to come back after a few months to re-test and to see if you need any treatment.

If people develop chronic infection, they will need treatment to help clear the virus. Where available, treatment with drugs called direct-acting antivirals can cure hepatitis in most cases. These are usually taken for 8-12 weeks. Your doctor will also check your liver for any damage.

If youve had hepatitis C in the past, youre not immune to future infections which means you can get it again. You can also still get other types of hepatitis, and having hepatitis C together with another type is more serious.

If youve already had hepatitis C, its advisable to have the vaccination against hepatitis A and B to protect your liver from further damage.

Whether you have symptoms or not, dont have sex until your healthcare professional says you can.

How Do You Prevent Hepatitis

Both hepatitis A and hepatitis B can be prevented with a vaccine. There is currently no vaccine available to prevent hepatitis C.

To prevent spreading or getting hepatitis A:

  • Wash hands with soap and warm water for at least 20 seconds after using the bathroom, changing diapers, touching garbage or dirty clothes, and before preparing food and eating
  • Follow guidelines for food safety
  • Avoid unpasteurized milk or foods made with it
  • Thoroughly wash fruits and vegetables before eating
  • Keep the refrigerator colder than 40°F and the freezer below 0°F
  • Cook meat and seafood until well done
  • Cook egg yolks until firm
  • Wash hands, knives, and cutting boards after contact with raw food

To prevent spreading or getting hepatitis B or hepatitis C:

  • Practice safe sex and use a latex condom each time you have sex
  • Dont share razors, toothbrushes, or any personal objects that might have blood on them
  • Dont share needles or syringes
  • Cover cuts and open sores with bandages
  • Clean blood off of things with a mixture of bleach and water: use 9 parts bleach to one-part water

Whos At Risk For Hepatitis C

No Identifiable Source Of Infection

According to the Centers for Disease Control and Prevention, injection drug use accounts for approximately 60% of all HCV infections in the United States, while other known exposures account for 20-30%. Approximately 10% of patients in most epidemiological studies, however, have no identifiable source of infection. HCV exposure in these patients may be from a number of uncommon modes of transmission, including vertical transmission, and parenteral transmission from medical or dental procedures prior to the availability of HCV testing. There are no conclusive data to show that persons with a history of exposures such as intranasal cocaine use, tattooing or body piercing are at an increased risk for HCV infection based on these exposures solely. It is believed, however, that these are potential modes of HCV acquisition in the absence of adequate sterilization techniques.

How Hbv Is Spread

Perinatal Hepatitis C, 2016 Newsroom Release

It is possible for the hepatitis B virus to be spread through the bodily fluids of an infected person, which is to say that the virus can be transmitted through the blood, sweat, tears, saliva, semen, vaginal secretions, menstrual blood, and breast milk of an infected person. That said, having hepatitis B does not necessarily mean that you are infectious only some people with HBV are actually contagious.

Opportunities for exposure can include sharing a syringe or getting tattoos or body piercings with infected tools. But it also means that it is possible to be exposed during childbirth as well as sexual contact and intercourse. In fact, nearly two-thirds of acute cases of hepatitis B in the United States are caused by sexual exposure.

Though HBV can be spread through blood, there is generally very little risk of contracting the virus through blood transfusions as most countries began screening for it by 1975.
