How Can Hepatitis B And C Be Transmitted

How Hbv Is Spread

How is Hepatitis B & C transmitted? | Apollo Hospitals

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.

What Are The Symptoms Of Hepatitis B

Many people with hepatitis B dont have any symptoms. If you do get symptoms you may not notice them until two or three months after infection and they can last up to three months. There are two types of infection acute and chronic.

Acute symptoms include:

  • flu-like symptoms, including tiredness, fever and aches and pains
  • feeling and/or being sick
  • jaundice, meaning your skin and the whites of your eyes turn yellow
  • dark urine
  • pale faeces .

People who cant fight off acute infection after six months, such as babies, young children and people with a weakened immune system because of HIV, can go on to develop chronic hepatitis B. This is when people are at higher risk of liver failure, liver disease and cancer of the liver.

What Is The Treatment For Hepatitis

Each type of hepatitis is treated differently.

Hepatitis A often goes away on its own and home treatment is all that is needed to help the liver recover, such as:

  • Rest
  • Avoiding alcohol
  • Avoiding certain medicines that can be harmful to the liver

Hepatitis B often goes away on its own in about 6 months, and can also be treated at home with the above remedies. Other treatments for hepatitis B include:

Treatment for hepatitis C is effective on certain forms of the hepatitis C virus. The choice of medications depends on the type of hepatitis C you have, whether you have been treated for the illness before, how much liver damage has occurred, any other underlying medical issues, and other medicines you take. Treatment for hepatitis C usually involves 8 to 12 weeks of oral antiviral medications, such as:

  • Elbasvir-grazoprevir
  • Sofosbuvir-velpatasvir-voxilaprevir

Who Is Most Affected

In the United States, rates of new HBV infections are highest among adults aged 40-49 years, reflecting low hepatitis B vaccination coverage among adults at risk. The most common risk factor among people with new HBV infections is injecting drugs, related to the opioid crisis.

The highest rates of chronic hepatitis B infection in the United States occur among foreign-born individuals, especially people born in Asia, the Pacific Islands, and Africa. Approximately 70% of cases in the United States are among people who were born outside of the United States. CDC developed this map of the geographic distribution of hepatitis B around the world – PDF. Other groups who have higher rates of chronic HBV infection include people who inject drugs and men who have sex with men.

Hepatitis E: Causes, symptoms, and treatment

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.

What Are The Risk Factors

Some people are at an increased risk for contracting HAV, including:

  • people traveling to areas of the world where hepatitis A is common
  • men who have sex with men
  • people who use injectable or noninjectable drugs
  • caregivers for those who have hepatitis A
  • people who are experiencing homelessness
  • people living with a child whos been adopted from an area where hepatitis A is common

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.

What Are The Chances Of Getting Hepatitis C From Sex

How Is Hepatitis Transmitted?

Hepatitis C can spread through sexual intercourse, but it’s rare. And it’s extremely rare among monogamous couples. In fact, the CDC considers the risk of sexual transmission between monogamous couples so low that it doesn’t even recommend using condoms. Also, there’s no evidence that hepatitis C is spread by oral sex. But you should avoid sharing razors, toothbrushes, and nail clippers, and sex during menstruation.

If you have HIV or if you have multiple partners, you should take precautions. Using condoms will protect you and your partners.

Enteric Routes: Transmission Of Hepatitis A And Hepatitis E

The Hepatitis A and hepatitis E viruses are both transmitted by enteric, that is digestive or by fecal, routes. This is also known as the fecal-oral route. To be exposed to these viruses, you must ingest fecal matter that is infected with the virus. While there are several ways in which this fecal-oral route can be established, poor hygiene and poor sanitary conditions in some countries lead to higher rates of infection of these viruses.

As a result, some areas of the world, like India, Bangladesh, and Central and South America, are particularly prone to the hepatitis E virus. About one-third of people in the United States have been exposed to the hepatitis A virus.

It is believed that the hepatitis F virus may also be spread by enteric routes.

Hepatitis C: Who Is At Risk

People who have injected illegal drugs at any time, even one time, many years ago, could be walking around with chronic hepatitis C. Because there are often no symptoms, many former drug users may not realize they have the infection. People who received a blood transfusion before 1992 also have a higher risk. Before that year, donated blood was not screened for the hepatitis C virus.

What Is The Treatment For Hepatitis B

Prevention is recommended by receiving a vaccine for HBV.

Receiving an injection of the hepatitis B immune globulin within 12 hours of coming in contact with the virus may help prevent the development of the disease.

At present, there is no specific treatment for patients with acute hepatitis B. Acute infection is usually short and will often resolve on its own. Your health care provider may recommend rest, and adequate nutrition and fluids to help your body fight the infection. Hospitalization may be required for patients who suffer from severe vomiting and who are unable to maintain adequate nutritional levels. It may also be required to prevent the development of complications.

While chronic infection cannot be cured, there are two standard treatments in Canada that may control the virus and prevent further damage to the liver.

  • Antiviral medications can fight the virus and slow damage to the liver.
  • Interferon which may be given for short periods and if effective, results in suppression of the virus.

Hepatitis And Sex: Frequently Asked Questions

Hepatitis C Symptoms: What Are They and What You Can Do

Itâs widely known that viral hepatitis can spread through consuming contaminated food or sharing dirty hypodermic needles. But the liver-destroying disease can also sometimes be spread through sexual contact. Hereâs what you need to know to protect yourself.

How many kinds of viral hepatitis are there?

Scientists have identified at least five types of viral hepatitis that lead to liver problems. In the U.S., the main threats are hepatitis A, hepatitis B, and hepatitis C.

Can all types be spread by sexual contact?

Hepatitis A spreads via fecal-oral contact, which can occur if there is direct oral-anal contact or contact with fingers or objects that have been in or near the anus of an infected person. If even a microscopic amount of virus-laden feces gets into the mouth, infection potentially can result.

Are men and women equally at risk of getting and spreading hepatitis through sex?

The risk is determined by a personâs behavior, not their gender, although some studies have shown that it is easier for a man to transmit HCV to a woman than vice versa.

Men who have sex with men are 10 to 15 times more likely than the general population to be infected with hepatitis B.

How can I make sure my partner is free of hepatitis before we have sex?

Are some sex acts especially likely to transmit hepatitis?

Any sexual activity that might cause abrasions, cuts, or other trauma is especially risky.

How Is It Treated

Hepatitis A is treated using supportive methods. These can include things like rest, fluids, and healthy foods. Medications can also help to ease some symptoms like fever, aches, and pains.

Theres a vaccine available to protect against infection with HAV. This is typically recommended for children as well as for people at an increased risk for contracting the virus.

Also, receiving a single dose of the hepatitis A vaccine may prevent you from becoming ill if youve been exposed to HAV. For it to be effective, the vaccine needs to be given of exposure.

Whats The Difference Between Hepatitis A B And C

Hepatitis is a condition that occurs when your liver becomes inflamed. There are several things that can cause hepatitis, including viral infections, autoimmune conditions, and heavy alcohol use.

Many times, hepatitis is caused by a virus. When this happens, its called viral hepatitis. The most common types of viral hepatitis in the United States are:

  • hepatitis A
  • hepatitis C

What is hepatitis?

Viral hepatitis is a condition that causes inflammation of your liver. When a hepatitis virus enters your body, it travels to the liver. It can then enter liver cells and begin to replicate, making more of itself.

The activity of the virus can cause damage to your liver cells. Immune cells begin to travel to your liver to fight the infection. This can also contribute to inflammation.

Liver damage and inflammation can affect your livers ability to function, which can in turn affect your overall health. This is because your liver has several important functions for your body, including:

  • breaking down or filtering various substances in the body, such as drugs and toxins
  • producing bile, which is important for digestion
  • making important blood proteins, including those that help your blood to clot
  • storing additional blood sugar as glycogen, which can be used for energy later
  • synthesizing immune system factors that are important for fighting infections

Symptoms of viral hepatitis

  • fever
  • yellowing of the skin or eyes
  • dark urine
  • pale, clay-colored stool

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.

Hepatitis A: What Happens

What is Hepatitis B? | How is Hepatitis B Transmitted?

Hepatitis A is highly contagious and can spread from person to person in many different settings. It typically causes only a mild illness, and many people who are infected may never realize they’re sick at all. The virus almost always goes away on its own and does not cause long-term liver damage.

Parenteral Routes: Transmission Of Hepatitis B Hepatitis D And Hepatitis C

Hepatitis B, C, and D viruses are all transmitted by what is known as the parenteral route. Parenteral simply means that these viruses can be introduced by all routes except through the intestinal tract, which leaves the door wide open in terms of possible exposure. Let’s look at the possible transmission routes for each of these types of hepatitis virus more closely.

Poor Infection Control For Tattooing And Piercing

The notes that HCV may be transmitted by receiving tattoos or piercings from unregulated settings with poor infection control standards.

Commercially licensed tattooing and piercing businesses are generally thought to be safe.

More informal settings may not have adequate safeguards to help avoid the spread of infections. Receiving a tattoo or piercing in settings such as in a prison or in a home with friends carries a of HCV transmission

You Might Not Know You Have It

Nearly half of people living with hepatitis C dont know they have it. Thats because most people live with the disease for years without feeling sick, or experiencing only minor symptoms such as fatigue. Frequently, the only indication of hepatitis C is an abnormal liver blood test panel. If you think you have been exposed to hepatitis C, be sure to talk to your physician.

How Do You Get Hepatitis B

Hepatitis B Reactivation with Hepatitis C Treatment

Hepatitis B is really contagious. Its transmitted through contact with semen , vaginal fluids, and blood. You can get it from:

  • having vaginal, anal, or oral sex

  • sharing toothbrushes and razors

  • sharing needles for shooting drugs, piercings, tattoos, etc.

  • getting stuck with a needle that has the Hep B virus on it.

Hepatitis B can also be passed to babies during birth if their mother has it.

Hepatitis B isnt spread through saliva , so you CANT get hepatitis B from sharing food or drinks or using the same fork or spoon. Hepatitis B is also not spread through kissing, hugging, holding hands, coughing, sneezing, or breastfeeding.

How To Reduce Your Risk

Dont share needles or other drug-use equipment. If you use intravenous drugs, take part in a needle exchange program.

Dont share personal care articles, such as razors, scissors, nail clippers or toothbrushes, with an infected person.

If you get a tattoo, body piercing or acupuncture, make sure all equipment is clean and sterile. Needles should always be new, not used, and never homemade.

Wear latex gloves whenever you might come into contact with someone elses blood or body fluids.

The Types Of Viral Hepatitis

There are five main types of viral hepatitis known as hepatitis A , hepatitis B , hepatitis C , hepatitis D , and hepatitis E . That said, there have been cases of acute hepatitis that could not be attributed to one of these five types of hepatitis viruses, alcohol, drugs, or autoimmune disease, which lead researchers to try to find another cause.

Though the etiology of these viruses have not yet been fully established, researchers have identified three other types of viral hepatitis , which they have named hepatitis F , hepatitis G , and transfusions transmitted virus . As relatively new diseases and viral discoveries, information about them and how they work is relatively scarce. We do know, however, that cases of TTV have only been associated with hepatitis in people who have had a blood transfusion.

The Abcs Of Hepatitis B And C

Hepatitis is an infection or inflammation of the liver. It is most commonly caused by a viral infection. There are 6 types of hepatitis viruses types A, B, C, D, E and G.

Two types, hepatitis B and hepatitis C, are linked to cancer.

Hepatitis B is the most common type of hepatitis virus. It is very infectious and is spread mainly by being exposed to infected blood or other bodily fluids . HBV is more likely to cause symptoms than hepatitis C.

HBV infection can cause flu-like symptoms and yellowing of the skin and whites of the eyes . Most people recover completely from HBV infection within a few months and develop lifelong protection against it. Only about 10% of people have an infection that lasts a long time.
