How Does Hepatitis B And C Spread

Are Hepatitis B And C Preventable

How is Hepatitis B & C transmitted? | Apollo Hospitals

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.

How Do Doctors Treat The Complications Of Hepatitis B

If chronic hepatitis B leads to cirrhosis, you should see a doctor who specializes in liver diseases. Doctors can treat the health problems related to cirrhosis with medicines, minor medical procedures, and surgery. If you have cirrhosis, you have an increased chance of liver cancer. Your doctor may order blood tests and an ultrasound or another type of imaging test to check for liver cancer.

If chronic hepatitis B leads to liver failure or liver cancer, you may need a liver transplant.

How To Prevent Transmission

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.

What Laboratory Tests Are Available For Hepatitis B

Tests are available to detect the types of antigens used to identify the hepatitis B virus. The tests determine if the virus is present in the body tissue or blood. The amount of each type of antigen present indicates how advanced the disease is and how infective the individual has become.

Other tests are available to detect the body’s reaction to the viral infection or the body’s reaction to vaccination against the virus. These tests work by measuring the number of antibodies present in the blood.

Chronic Hepatitis B Complications

Hepatitis B Reactivation with Hepatitis C Treatment

Chronic hepatitis B can lead to

  • cirrhosis, a condition in which scar tissue replaces healthy liver tissue and prevents your liver from working normally. Scar tissue also partly blocks the flow of blood through the liver. As cirrhosis gets worse, the liver begins to fail.
  • liver failure, in which your liver is badly damaged and stops working. Liver failure is also called end-stage liver disease. People with liver failure may require a liver transplant.
  • liver cancer. Your doctor may suggest blood tests and an ultrasound or another type of imaging test to check for liver cancer. Finding cancer at an early stage improves the chance of curing the cancer.

Keep Personal Items Personal

Any tools or implements that may have a bit of blood on them from infected people are potential sources of hepatitis B or C transmission. Toothbrushes, nail clippers, razors, needles, and washcloths may all contain trace amounts of blood that can transmit infection. Keep personal items such as these to yourself and never use personal items that belong to others.

Treatment: Chronic Hepatitis B

The goal of treating chronic hepatitis B is to control the virus and keep it from damaging the liver. This begins with regular monitoring for signs of liver disease. Antiviral medications may help, but not everyone can take them or needs to be on medication. Be sure to discuss the risks and benefits of antiviral therapy with your doctor.

Hepatitis A And B Vaccines

There are vaccines to protect against hepatitis A and B. The CDC recommends hepatitis A vaccination for all children ages 12 to 23 months and for adults who plan to travel or work in areas with hepatitis A outbreaks or who have other risk factors. People with chronic hepatitis B or C should also get the hepatitis A vaccine if they don’t already have immunity to the disease. The hepatitis B vaccine is recommended for all infants at birth and for adults who have any of the risk factors we discussed earlier. There is no vaccine for hepatitis C.

Hepatitis A: How Does It Spread

How Does Hepatitis C Hurt Your Liver? | WebMD

It usually spreads through food or water. Food can be tainted when it’s touched by a person with hepatitis who did not wash their hands after using the bathroom. This transfers tiny amounts of infected stool to the food. Raw shellfish, fruits, vegetables, and undercooked foods are common culprits in hepatitis A outbreaks. The virus can also spread in daycare centers if employees aren’t careful about washing hands after changing diapers.

How Can You Prevent Hepatitis B And Hepatitis C

Hepatitis B: Vaccination is the best way to prevent all of the ways that hepatitis B is transmitted. People with HIV who do not have active HBV infection should be vaccinated against it. In addition to the 3-dose series of hepatitis B vaccine given over 6 months, as of 2017, there is a 2-dose series given over 1 month.

Hepatitis C: No vaccine exists for HCV and no effective pre- or postexposure prophylaxis is available. The best way to prevent hepatitis C infection is to never inject drugs or to stop injecting drugs by getting into and staying in drug treatment. If you continue injecting drugs, always use new, sterile needles or syringes, and never reuse or share needles or syringes, water, or other drug preparation equipment.

How Many People Have Hepatitis B

In the United States, an estimated 862,000 people were chronically infected with HBV in 2016. New cases of HBV infection in the United States had been decreasing until 2012. Since that time, reported cases of acute hepatitis B have been fluctuating around 3,000 cases per year. In 2018, 3,322 cases of acute hepatitis B were reported however, because of low case detection and reporting, the Centers for Disease Control and Prevention estimates that there were 21,600 acute hepatitis B infections. New HBV infections are likely linked to the ongoing opioid crisis in the United States.

Globally, HBV is the most common blood-borne infection with an estimated 257 million people infected according to the World Health Organization .

Sexual Transmission And Viral Hepatitis

Certain adults who are sexually active should be vaccinated against hepatitis B.

CDC and the Advisory Committee on Immunization Practices recommend hepatitis B vaccination for

  • sexually active people with more than one sex partner during the previous 6 months
  • people seeking evaluation or treatment for a sexually transmitted disease
  • sex partners of people with hepatitis B and
  • men who have sex with men .

CDC recommends one-time hepatitis C testing of all adults and regular testing for people with risk factors.

Is Hepatitis Testing Recommended For People With Hiv

Hepatitis B virus information

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.

Should I Be Screened For Hepatitis B

Screening is testing for a disease in people who have no symptoms. Doctors use blood tests to screen for hepatitis B. Many people who have hepatitis B dont have symptoms and dont know they are infected with hepatitis B. Screening tests can help doctors diagnose and treat hepatitis B, which can lower your chances of developing serious health problems.

Your doctor may recommend screening for hepatitis B if you9,14

  • are pregnant
  • were born in an area of the world where 2 percent or more of the population has hepatitis B infection, which includes Africa, Asia, and parts of the Middle East, Eastern Europe, and South America
  • didnt receive the hepatitis B vaccine as an infant and have parents who were born in an area where 8 percent or more of the population had hepatitis B infection, which includes sub-Saharan Africa and parts of Asia
  • are HIV-positive
  • are a man who has sex with men
  • have lived with or had sex with a person who has hepatitis B
  • have an increased chance of infection due to other factors

Treatment: Chronic Hepatitis C

How Is Hepatitis Transmitted?

The latest drug to be approved by the FDA is glecaprevir and pibrentasvir . This medication offers a shorter treatment cycle of 8 weeks for adult patients with all types of HCV who donât have cirrhosis and who have not been previously treated. The length of treatment is longer for those who are in a different disease stage. The prescribed dosage for this medicine is 3 tablets daily.

There are several other combination drugs available, as well as some single drugs that may be used in combination. Your doctor will choose the right one for you depending on the type of hepatitis C you have, how well your liver is functioning and any other medical problems you may have. Also be sure to discuss your insurance coverage since these medications are expensive.

Effective Treatments Are Available For Hepatitis C

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.

What Causes Hepatitis B

The hepatitis B virus causes hepatitis B. The hepatitis B virus spreads through contact with an infected persons blood, semen, or other body fluids. Contact can occur by

  • being born to a mother with hepatitis B
  • having unprotected sex with an infected person
  • sharing drug needles or other drug materials with an infected person
  • getting an accidental stick with a needle that was used on an infected person
  • being tattooed or pierced with tools that were used on an infected person and werent properly sterilized, or cleaned in a way that destroys all viruses and other microbes
  • having contact with the blood or open sores of an infected person
  • using an infected persons razor, toothbrush, or nail clippers

You cant get hepatitis B from

  • being coughed on or sneezed on by an infected person
  • drinking unclean water or untreated water that has not been boiled
  • eating food that is unclean or has not been properly cooked
  • hugging an infected person
  • shaking hands or holding hands with an infected person
  • sharing spoons, forks, and other eating utensils
  • sitting next to an infected person

Mothers who have hepatitis B can safely breastfeed their babies. If a baby receives hepatitis B immune globulin and starts receiving the hepatitis B vaccine to prevent hepatitis B infection shortly after birth, hepatitis B is unlikely to spread from mother to child through breastfeeding.15

Who Should Be Tested For Hepatitis

Hepatitis B vs. hepatitis C: Differences and which is worse

Testing is important for anyone with the risk factors we’ve mentioned, particularly injected drug users and people who have had multiple sex partners. Health advocates are also urging people of Asian heritage to get tested. Stanford University’s Asian Liver Center estimates that 1 in 10 Asians living in the U.S. has chronic hepatitis B. Many of them have probably had the virus since birth.

Also, the U.S. Preventive Services Task Force recommends that health care providers offer a one-time hepatitis C screening for anyone born between 1945 and 1965.

Sexual Transmission And Hepatitis A

Transmission of hepatitis A virus can occur from any sexual activity with an infected person and is not limited to fecal-oral contact. People who are sexually active are considered at risk for hepatitis A if they are MSM, live with or are having sex with an infected person, or inject drugs. Vaccination is the most effective means of preventing hepatitis A transmission among people at risk for infection. CDC has published recommendations for prevention of hepatitis A that identify all groups recommended for vaccination, including hepatitis A vaccination for MSM.

How Is Hepatitis C Transmitted

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.

Other Body Fluids And Tissues

Hepatitis B is found in semen and vaginal secretions. The virus can be transmitted during unprotected sexual intercourse, and from mother to infant during birth.

Synovial fluid , amniotic fluid, cerebrospinal fluid, and peritoneal fluid can contain the hepatitis B virus, but the risk of transmission to workers is not known.

Feces, nasal secretions, sputum, sweat, tears, urine, and vomit have not been implicated in the spread of hepatitis B. Unless they are visibly contaminated with blood, the risk of contracting hepatitis B from these fluids in the workplace is very low.

Hepatitis B is not transmitted by casual contact. For example, hospital employees who have no contact with blood, blood products, or blood-contaminated fluids are at no greater risk than the general public. However, the virus can spread through intimate contact with carriers in a household setting, possibly because of frequent physical contact with small cuts or skin rashes. The virus can also spread through biting and possibly by the sharing of toothbrushes or razors. It is not spread through sneezing, coughing, hand holding, hugging, kissing, breastfeeding, sharing eating utensils, water or food.

Hepatitis C: What Happens

Hepatitis C Virus

About 25% of people who get hepatitis C defeat the virus after a short-term infection. The rest will carry the virus in their body for the long term. Chronic hepatitis C can cause very serious complications, including liver failure and liver cancer. There are effective treatments for the virus, though.
