To get immunized against Hepatitis A make an appointment with your doctor, pharmacist or Public Health.

Those not eligible for a free Hepatitis A vaccine can buy it at most pharmacies and travel clinics.

Can Hbv Infection Be Prevented

Yes. The best way to prevent HBV is to get the hepatitis B vaccine.

CDC recommends that people with HIV and people who are at risk for HIV get the HBV vaccine . The housemates and sexual partners of people with HBV should get the HBV vaccine, too.

People, including people with HIV, can also take the following steps to reduce their risk of HBV infection:

  • Use condoms during sex to reduce the risk of HBV infection and infection with other sexually transmitted diseases, such as gonorrhea and syphilis.
  • Do not inject drugs. But if you do, do not share needles, syringes, or other drug injection equipment.

How Is Hepatitis A Spread

The hepatitis A virus is found in the stool and blood of people who are infected. The hepatitis A virus is spread when someone ingests the virus, usually through:

Person-to-person contact
Eating contaminated food or drink

Contamination of food with the hepatitis A virus can happen at any point: growing, harvesting, processing, handling, and even after cooking. Contamination of food and water happens more often in countries where hepatitis A is common. Although uncommon, foodborne outbreaks have occurred in the United States from people eating contaminated fresh and frozen imported food products.

Hepatitis A can be prevented with a safe and effective vaccine.

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 Is Autoimmune Hepatitis Treated

The goal of treatment is to stop the bodys attack on itself by suppressing the immune system. This is accomplished with a medicine called prednisone, a type of steroid. Often times, a second drug, azathioprine is also used. Treatment starts with a high dose of prednisone. When symptoms improve, the dosage is lowered and azathioprine may be added. In most cases, autoimmune hepatitis can be controlled but not cured. That is why most patients will need to stay on the medicine for years, and sometimes for life. Unfortunately, long-term use of steroid can cause serious side effects including diabetes, osteoporosis, high blood pressure, glaucoma, weight gain and decreased resistance to infection. Other medications may be needed to control these side effects.

Make sure everyone in your household gets the hepatitis B vaccine. An important step is to see a specialist to discuss treatment options.

What Is A Bloodborne Pathogen

Microorganisms found in human blood and fluids can develop into human disease. They are referring to bloodborne pathogens when this language is in use. A bloodborne pathogen is a type of bacteria or virus that lives and thrives in your blood.

These pathogens include some of the most contagious diseases we are aware of today, such as HIV/AIDS, hepatitis B, and hepatitis C.

The human immunodeficiency virus is a virus that attacks human T-cells. HIV inhibits the ability of an individual to combat other germ-causing diseases. It can contribute to the development of acquired immune deficiency syndrome .

HIV may spread by workers exposed to an HIV-contaminated patients plasma or waste. It can spread by sexual intercourse with a contaminated person or exchanging needles. It can even spread to a fetus in the womb of a person who has the disease.

The risk can be lowered with appropriate precautions taken before birth.

You cannot contract HIV from telephones, toilets, door handles, or bug bites. You cant get HIV by giving blood by touching hands, getting sneezed on, or coughed on. These common misconceptions hold no actual truth.

Just like hepatitis B, you can get this type by sharing needles or having contact with infected blood. You can also catch it by having sex with somebody whos infected, but thats less common.

If you had a blood transfusion before new screening rules were put in place in 1992, you are at risk for hepatitis C. If not, the blood used in transfusions today is safe. It gets checked beforehand to make sure its free of the virus that causes hepatitis B and C.

Its rare, but if youre pregnant and have the disease, its possible to pass it to your newborn.

There are some myths out there about how you get hepatitis C, so lets set the record straight. Its not spread by food and water . And you canât spread it by doing any of these things:

See your doctor as soon as possible if you have any of these symptoms.

Sometimes, people have no symptoms. To be sure you have hepatitis, youâll need to get tested.

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.

You Might Not Know You Have It

Nearly half of people living with hepatitis C dont know they have it.

What Is Viral Hepatitis

Hepatitis means inflammation of the liver. The liver is a vital organ that processes nutrients, filters the blood, and fights infections. When the liver is inflamed or damaged, its function can be affected. Heavy alcohol use, toxins, some medications, and certain medical conditions can cause hepatitis. However, hepatitis is often caused by a virus. In the United States, the most common types of viral hepatitis are hepatitis A, hepatitis B, and hepatitis C.

The Dangers Of Transmission

Hepatitis A: How is it spread?

Life post-exposure can be tricky, depending on the nature of the bloodborne illness after contraction. HBV therapy entails treating the associated nausea, vomiting, and fatigue with hospice care. Treatment strategies for HBV infection have changed.

Since the announcement of the 2008 recommendations for disease treatment, several antibiotics are still delivered, which is an exciting development for this virus. Ninety percent of people receive either of these latest oral dosage forms, which contributes towards antimicrobial therapy.

In the United States, safe hepatitis B vaccines have been available since 1981. Vaccines of hepatitis B attempt to improve prevention efforts. For people living with hepatitis B, this is a beautiful improvement.

Many people have an affliction of HBV, several of whom dont recognize their disease condition .

Is Hepatitis B Contagious

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.

But there are many treatment options available and multiple ways you can prevent infection, including getting vaccinated.

If you suspect you may have been exposed to hepatitis B, its important to talk with a doctor to prevent infection and determine the best course of treatment for you.

What Are The Symptoms Of Hepatitis A

Hepatitis A may present with no symptoms in young children and in some, it may present 2-6 weeks after coming in contact with the virus. The symptoms when present usually last few weeks to 2 months, but in some individuals they may last up to 6 months. The symptoms when present may look like flu symptoms such as weakness, fatigue, nausea, vomiting, muscle soreness, abdominal discomfort and pain, fever, diarrhea, gray or clay colored stools and decreased appetite. Symptoms that are more specific of liver inflammation include dark yellow urine, and jaundice .

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

Important Questions And Needs For Future Research

  • How does HBV establish productive infection in vivo and what is the host response early during the infection? Despite well-described information on the clinical manifestations and natural history of acute HBV infection, detailed knowledge of the virus-host interaction during this stage remains poorly defined. Advances in this area would offer a better understanding of the pathogenesis of HBV infection and its associated disease.

  • What is the immunologic basis of chronic infection and hepatocellular injury? There have been great strides in understanding the virology and immune response of HBV infection, but the molecular mechanisms whereby the host fails to clear the virus and develops chronic infection remain largely unknown. In addition, the adaptive evolution of virus under host immune pressure remains to be elucidated. Finally, the pathogenesis of various extra-hepatic manifestations associated with HBV infection is poorly understood. Further research in these areas is crucial not only in better understanding the natural history and disease progression but also in improving treatment for chronic hepatitis B.
