Which Hepatitis Is The Most Contagious

There Is A Test For Hepatitis C

Hepatitis B: Explained

The hepatitis C antibody test determines if a person has been infected with the virus. A positive, or reactive result, means antibodies were found and you were infected with the hepatitis C virus at some point in time. Additional tests are required to confirm if you have active infection at present.

What Causes Hepatitis A

Hepatitis A is caused by infection with the hepatitis A virus. You get the virus when you unknowingly eat a small amount of infected feces. This can happen through person-to-person contact, or through eating or drinking contaminated food or water.

A person can have and spread hepatitis A, even if that person does not have any symptoms. You are most likely to get hepatitis A from another person when:

  • A person who has the virus does not wash their hands properly after going to the bathroom
  • A parent does not wash their hands properly after changing the diaper of an infected child
  • A caregiver does not wash their hands properly after cleaning up the stool of an infected person
  • A person has sex with a person who has the virus

You can also get infected with hepatitis A by eating contaminated food or drinking contaminated water. Contaminated food and water are more common in developing countries. When traveling in areas where hepatitis A is common, avoid eating raw fruits and vegetables, shellfish, ice, and untreated water.

How Common Is Hepatitis A

Since the hepatitis A vaccine was first recommended in 1996, cases of hepatitis A in the United States have declined dramatically. Unfortunately, in recent years the number of people infected has been increasing because there have been multiple outbreaks of hepatitis A in the United States. These outbreaks have primarily been from person-to-person contact, especially among people who use drugs, people experiencing homelessness, and men who have sex with men.

Who Should Receive The Hepatitis A Vaccine

In general, CDC recommends the following groups be vaccinated for hepatitis A:

  • All children at age 1 year
  • Travelers to countries that have high rates of hepatitis A
  • Family members and caregivers of recent adoptees from countries where hepatitis A is common
  • Men who have unprotected sexual contact with other men
  • Users of injection and illegal drugs
  • People with chronic liver diseases, hepatitis B, or hepatitis C
  • People who are treated with clotting-factor concentrates
  • People who work with hepatitis A infected animals or in a hepatitis A research laboratory

Hepatitis B: How Does It Spread

You can get it through contact with the blood or body fluids of an infected person. In the U.S., it’s most often spread through unprotected sex. It’s also possible to get hepatitis B by sharing an infected person’s needles, razors, or toothbrush. And an infected mother can pass the virus to their baby during childbirth. Hepatitis B is not spread by hugging, sharing food, or coughing.

What Are The Treatments For Hepatitis B

If you think you may have been exposed to hepatitis B, its important to talk with a healthcare professional as soon as possible.

A doctor or other healthcare professional may administer the first dose of the hepatitis B vaccine and a shot of hepatitis B immunoglobulin. This is a combination of antibodies that provide short-term protection against the virus.

Though both can be given up to a week after exposure, theyre most effective at preventing infection if administered within 48 hours.

If you receive a diagnosis of acute hepatitis B, a doctor may refer you to a specialist. They may advise you to get regular blood tests to ensure you dont develop chronic hepatitis.

Many people with acute hepatitis B dont experience serious symptoms. But if you do, it can help to:

  • get plenty of rest
  • take over-the-counter pain mediation, like naproxen, when needed

Other lifestyle changes may also be needed to manage your infection, such as:

  • eating a nutritious, balanced diet
  • avoiding substances that can harm your liver, such as:
  • alcohol
  • certain herbal supplements or medications, including acetaminophen

If blood tests show you still have an active infection after 6 months, your doctor may recommend further treatment, including medications to help control the virus and prevent liver damage.

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.

Can Hepatitis Be Treated

A Deep Dive into Hepatitis C

Michael says, Now we have more options which are better for the patient and more affordable.

Each form of hepatitis has its method of treatment. Once you know what type of hepatitis you have, you can expect the following treatment process:

  • Hepatitis A is a short-term illness that responds well to bed rest, hydration, and nutrition.
  • Hepatitis B in its acute form doesnt require treatment but the chronic form of the disease is treated with antiviral medications.
  • Hepatitis C is also treated with antiviral medication for both the acute and chronic forms of the disease.
  • Hepatitis D doesnt have a very effective treatment regimen at this time there is a medication available but it has low efficacy.
  • Hepatitis E usually resolves on its own as a short-term illness.

For prevention, there is a vaccine available to target hepatitis A and hepatitis B. You can also prevent hepatitis D by getting the hepatitis B vaccine. If you believe you have symptoms of hepatitis please call Gastroenterology Associates of Southwest Florida, PA for an appointment at 239-275-8882.

Who Is At Risk

Anyone who has not been vaccinated or previously infected can get infected with the hepatitis A virus. In areas where the virus is widespread , most hepatitis A infections occur during early childhood. Risk factors include:

  • poor sanitation
  • living in a household with an infected person
  • being a sexual partner of someone with acute hepatitis A infection
  • use of recreational drugs
  • travelling to areas of high endemicity without being immunized.

Hepatitis C Is The Most Common Type Of Chronic Viral Hepatitis In The United States

Viral hepatitis is a group of infectious diseases that causes inflammation of the liver. There are five types of viral hepatitis, but the most common in the United States are hepatitis A, B and C.

Hepatitis A

If you travel internationally, you should be aware of your risks for hepatitis A. New cases most commonly result from American travelers who get infected while traveling to parts of the world where hepatitis A is common. Hepatitis A is spread by consuming food or water contaminated with fecal matter from an infected person, or by eating raw shellfish from water contaminated by sewage. Hepatitis A is an acute process. It never is a chronic disease and does not cause cirrhosis.

Prevention: The hepatitis A vaccine is recommended for children people with certain risk factors and international travelers. It requires two rounds of shots to be effective. Washing your hands and avoiding unsanitary drinking water or food washed with unsanitary water is also important. If you become infected, your body is usually able to clear the infection itself within a few weeks.

Hepatitis B

Prevention: Doctors recommend that all children get the hepatitis B vaccine. If you become infected, hepatitis B can range from a mild illness to a serious condition requiring hospitalization, and in some cases, it can become a chronic, lifelong problem.

Hepatitis C

Who Is Most Affected

Anyone who has not been vaccinated or previously infected can become infected with HAV. The most common risk factors among people with new HAV infections include: 1) drug use 2) having sex with an infected person 3) coming in direct contact with persons who have HAV infection 4) homelessness and 5) traveling to countries where HAV infection is more common.

For countries where HAV infection is common, the risk factors are poor sanitation and lack of clean, safe drinking water.

Treatment And Prevention Of Hepatitis A

Hepatitis C (HCV) Infections: Explaining Serology Patterns

Because hepatitis A virus infections can have serious health consequences, the Centers for Disease Control and Prevention recommends providing post-exposure prophylaxis for unvaccinated people who have consumed any contaminated food or water within two weeks of exposure.

PEP consists of:

  • Hepatitis A vaccine for people between the ages of 1 and 40 years
  • Hepatitis A virus-specific immunoglobulin for people outside of this age range, but the hepatitis A vaccine can be substituted if IG is not available.
  • Those with evidence of previous vaccination or who can confirm previous hepatitis A illness do not require PEP.

If you are unsure if you have been vaccinated against hepatitis A, contact your health professional to check your immunization records. If you have been vaccinated, no further action is needed. If you have never received the hepatitis A vaccine, getting a single dose within two weeks of exposure can protect against illness. If you are unable to determine whether you have already been vaccinated, receiving an additional dose of vaccine is not harmful if you have already been vaccinated.

Hepatitis A: Who Is At Risk

A prime risk factor for hepatitis A is traveling to or living in a country with high infection rates. You can check the CDC’s travel advisories to learn about recent outbreaks. Eating raw foods or drinking tap water can raise your risk while traveling. Children who attend daycare centers also have a higher risk of getting hepatitis A.

What Are The Types Of Hepatitis

The three most common types of hepatitis in the United States are A, B, and C, but there are five types in total. All of these forms of hepatitis target the livers ability to function. Here are the differences between them:

  • Hepatitis A is caused by the hepatitis A virus, which spreads through the blood and stool of people infected by the virus.
  • Hepatitis B is also caused by a virus spread through bodily fluids from an infected person however, it can be prevented through the use of vaccines.
  • Hepatitis C is also a viral form of hepatitis. It can be short-term or long-term. As a chronic infection, it can cause life-threatening health issues like cirrhosis or liver cancer.
  • Hepatitis D, also known as delta hepatitis, only occurs concurrently within people who also have the hepatitis B virus.
  • Hepatitis E,though not particularly common in the United States, can spread from eating raw or undercooked pork, shellfish, or wild game.

What Is Hepatitis E

Hepatitis E, also called enteric hepatitis , is similar to hepatitis A, and more prevalent in Asia and Africa. It is also transmitted through the fecal-oral route. It is generally not fatal, though it is more serious in women during pregnancy and can cause fetal complications. Most patients with hepatitis E recover completely.

How Hcv Is Spread

Infectious Diseases A-Z: Hepatitis A outbreak

The hepatitis C virus is transmitted primarily through blood to blood contact, meaning that a person can become infected with the virus should the blood of a person who carries the virus be introduced into another person’s bloodstream.

Therefore, as with hepatitis B, blood transfusions , tattooing and body piercing, occupational exposure, medical procedures, and intravenous drug use can all lead to possible exposure to the virus. Unlike hepatitis B, however, sexual contact and childbirth have both been shown to be an inefficient route of exposure to HCV.

The hepatitis G virus is thought to be transmitted in a similar way to HCV.

How Long Does It Last

Hepatitis A can last from a few weeks to several months.

Hepatitis B can range from a mild illness, lasting a few weeks, to a serious, life-long condition. More than 90% of unimmunized infants who get infected develop a chronic infection, but 6%10% of older children and adults who get infected develop chronic hepatitis B.

Hepatitis C can range from a mild illness, lasting a few weeks, to a serious, life-long infection. Most people who get infected with the hepatitis C virus develop chronic hepatitis C.

When To Get Medical Advice

See your GP for advice if:

  • you have symptoms of hepatitis A a blood test can usually confirm whether you have the infection
  • you might have been exposed to the hepatitis A virus recently but you do not have any symptoms treatment given early on may be able to stop the infection developing
  • you think you might need the hepatitis A vaccine your GP can advise you about whether you should have the vaccine

Although hepatitis A is not usually serious, it’s important to see your GP so they can rule out more serious conditions with similar symptoms, such as hepatitis C or scarring of ther liver .

It may also be necessary to test your friends, family and any sexual partners in case you have spread the infection to them.

Hepatitis B Surface Antigen Test

A hepatitis B surface antigen test shows if you have an active infection. A positive result means you have hepatitis B and can transmit the virus to others. A negative result means you dont currently have hepatitis B.

This test doesnt distinguish between chronic and acute infection. This test is used together with other hepatitis B tests to determine the state of a hepatitis B infection.

Hepatitis Types Symptoms And Treatments

Hepatitis A

Hepatitis is a disease that includes any type of inflammation of the liver, the result of a complex process that occurs when the liver suffers an injury. This can be confusing if you have a type of hepatitis that is not an infectious disease. The word hepatitis can simply be broken down into the words “hepa” which refers to the liver, and “itis” which refers to inflammation.

What Is Hepatitis B

Hepatitis B is a liver infection caused by the hepatitis B virus . HBV is one of five types of viral hepatitis. The others are hepatitis A, C, D, and E. Each is a different type of virus. Types B and C are most likely to become chronic, or long lasting.

According to the , around 296 million people around the world are living with hepatitis B. Around 1.5 million people newly contracted chronic hepatitis B in 2019.

HBV infection can be acute or chronic.

Acute hepatitis B causes symptoms to appear quickly in adults. Infants who contract it at birth rarely develop only acute hepatitis B. Nearly all hepatitis B infections in infants go on to become chronic.

Chronic hepatitis B develops slowly. Symptoms may not be noticeable unless complications develop.

Symptoms of acute hepatitis B may not be apparent for months. But common symptoms include:

  • fatigue
  • weakness
  • yellowing of the whites of the eyes and skin

Any symptoms of hepatitis B need urgent evaluation. Symptoms of acute hepatitis B are worse in people over age 60.

Let your doctor know immediately if youve been exposed to hepatitis B. You may be able to prevent infection.

Hepatitis B is a viral infection thats transmitted through blood or other bodily fluids, including semen or vaginal fluids.

Some of the ways hepatitis B can be transmitted include:

Although the virus may be found in the saliva, hepatitis B is not transmitted through:

  • kissing

To screen for hepatitis B, your doctor will perform a series of blood tests.

Is There A Possibility Of Coinfection

Both hepatitis B and C can be present at the same time. Hepatitis C may become more dominant, reducing hepatitis B levels in the bloodstream to low or undetectable levels.

Prior to starting hepatitis C treatment, people should have their blood tested for hepatitis B using the three-part blood test . According to the American Association for the Study of Liver Diseases treatment guidelines, people who are currently infected with hepatitis B or who have recovered from a previous infection should be managed carefully to avoid dangerous elevations in liver enzymes that can lead to liver failure.

Is Hepatitis B Contagious

Hepatitis A: How is it spread?

Hepatitis B is highly contagious. Its transmitted through contact with blood and certain other bodily fluids. Although the virus can be found in saliva, its not transmitted through sharing utensils or kissing. Its also not transmitted through sneezing, coughing, or breastfeeding.

Symptoms of hepatitis B may not appear for 3 months after exposure. Symptoms can last for several weeks.

But even without symptoms, you can still transmit the infection to others. The virus can live outside the body and remains infectious for at least

Hepatitis B is a highly contagious condition. Its associated with many serious complications, some of which can be life threatening.
