Treatment Of Hepatitis A

Hepatitis A Overview:

Hepatitis is a general term that means inflammation (irritation and swelling) of the liver. Inflammation of the liver can result from infection, exposure to alcohol, certain medications, chemicals, poisons, or from a disorder of the immune system.

Hepatitis A refers to liver inflammation caused by infection with the hepatitis A virus (HAV). HAV is one of several viruses that can cause hepatitis, and is one of the three most common hepatitis viruses in the United States. The other two common types are hepatitis B and hepatitis C; however, there are other named types such as D, E, F, and G, and more types may be discovered in the future. Moreover, these infections are somewhat different from hepatitis A, and from each other.

Unlike hepatitis B and hepatitis C, hepatitis A does not cause chronic (ongoing, long-term) disease. Although the liver becomes inflamed and swollen, it heals completely in most people without any long-term damage. Once a person contracts hepatitis A, they develop lifelong immunity, and rarely contract the disease again.

Because of the way it is spread, the hepatitis A virus tends to occur in epidemics and outbreaks. As many as 1 in 3 adults (>age 19) in the United States have antibody to HAV , meaning they have been exposed to the virus, but most do not become ill. In 2011, researchers report no significant change in seroprevalence (the frequency of people in a population that have particular antibodies, usually reactive against a disease-producing organism in their blood serum) of HAV antibodies in adults before or after the HAV vaccine became available (see reference 3). The number of cases of hepatitis A in the United States varies among different communities, and has been reduced by the introduction of the hepatitis A vaccine. The rate of infection (number of infections per 100,000 people) has declined since 1999 from 6.3 to 0.9 per 100,000 people (2008 CDC statistics). About 2,500 to 3,600 cases of hepatitis A are reported each year in the U. S., but many more people may be exposed to the virus, but have few, if any, report symptoms. Vaccination at age one year may cause the rate and yearly case numbers of HAV to decline.

What is Hepatitis A?

In medical terminology, hepatitis A is described as an inflammatory disease of liver including short incubation period. The disease is caused by virus. Hepatitis A can be transmitted by fecal-oral contact or personal contact or through contaminated food or water.

Hepatitis A is a medical condition and on the rise among people. That’s what causes a major concern. There are people who don’t know much about hepatitis that can create a hell lot of problems. There are several types of hepatitis. Learning the different types can make a lot of difference in times of diagnosis.

It has been estimated that more than a million people all over the world falls victim to Hepatitis A. This virus is usually transmitted through drinking water and contaminated food intake. It’s not surprising that the developing countries have the largest population of Hepatitis A patients, where provision for clean drinking water and food is found to be inadequate.

According to research, places like Indonesia, Mexico, Greenland and the African continent includes high chance to get infected with the Hepatitis A. The Eastern European and Asian nations also include moderate risk of the HAV infection.

Hepatitis A Treatment:

Hepatitis A does not include any kind of specific treatment option. Normally people suffering from this disease are advised to take rest, avoid alcohol and all kinds of fatty foods as possible. Maintaining a well-balanced diet and staying hydrated can be of great help in such circumstances.

Prevention:

Medical reports suggest that Hepatitis A can be also be prevented by maintaining a good hygiene, sanitation and vaccination. The Hepatitis A is one of the major reasons why people tend to avoid surfing or going in the ocean after rains especially in the coastal areas. This is known to include a bad runoff.

Hepatitis A Vaccination:

Hepatitis A vaccine is helpful in protecting people. Reports suggest that vaccine can serve to be helpful in more than 95% cases in the last 10 years or so. The vaccine holds inactivated Hepatitis A virus offering active immunity against any future infection.

Vaccination was foremost phased in the year 1996 for children residing in the high-risk regions and areas. Later on in 1999, the system of giving Hepatitis A vaccine was spread to other areas as well.

The vaccine is usually injected into your upper arm muscle. It is said that an initial dose offers protection starting from 2 to 4 weeks after the vaccination. Another booster dose may be 6 to 12 months later offers protection for up to 20 years or so.

Hepatitis A:

Hepatitis A (formerly known as infectious hepatitis and epidemical virus) is an acute infectious disease of the liver caused by the hepatitis A virus (Hep A),an RNA virus, usually spread the fecal-oral route; transmitted person-to-person by ingestion of contaminated food or water or through direct contact with an infectious person. Tens of millions of individuals worldwide are estimated to become infected with Hep A each year. The time between infection and the appearance of the symptoms (the incubation period) is between two and six weeks and the average incubation period is 28 days.

In developing countries, and in regions with poor hygiene standards, the incidence of infection with this virus is high and the illness is usually contracted in early childhood. As incomes rise and access to clean water increases, the incidence of HAV decreases.Hepatitis A infection causes no clinical signs and symptoms in over 90% of infected children and since the infection confers lifelong immunity, the disease is of no special significance to those infected early in life. In Europe, the United States and other industrialized countries, on the other hand, the infection is contracted primarily by susceptible young adults, most of whom are infected with the virus during trips to countries with a high incidence of the disease or through contact with infectious persons.

HAV infection produces a self-limited disease that does not result in chronic infection or chronic liver disease. However, 10–15% of patients might experience a relapse of symptoms during the 6 months after acute illness. Acute liver failure from Hepatitis A is rare (overall case-fatality rate: 0.5%). The risk for symptomatic infection is directly related to age, with >80% of adults having symptoms compatible with acute viral hepatitis and the majority of children having either asymptomatic or unrecognized infection. Antibody produced in response to HAV infection persists for life and confers protection against reinfection. The disease can be prevented by vaccination, and hepatitis A vaccine has been proven effective in controlling outbreaks worldwide.

Treatment for hepatitis A:

There is no specific treatment for HAV and most people fight off the virus naturally, returning to full health within a couple of months. The doctor will advise avoiding alcohol and fatty foods as these can be hard for the liver to process and may exacerbate the inflammation.

Patients should get plenty of rest and eat a nutritious diet. They should also ensure they do not spread HAV by washing their hands after using the toilet and before preparing food. Patients with more severe symptoms may be monitored in hospital for a short period.

Hepatitis A immunisation

Hepatitis A immunisation is given in a series of injections. The first single injection in the arm gives protection for a year. The second booster injection at 6 to 12 months extends protection for up to 10 years.

The hepatitis A vaccine may be routinely recommended for young children living in areas with high incidence of hepatitis A, and anyone travelling to countries where hepatitis A is endemic. In addition, immunisation may be recommended for people whose sexual practices are likely to put them at risk.

Immunisation may also be recommended to prevent hepatitis A developing if a person suspects they have been exposed to the virus.

Follow-up

Someone who is infected with hepatitis A should limit the amount of alcohol they drink. Their doctor may also offer dietary advice.

The doctor will advise about any precautions

necessary to avoid infecting others with the virus.

Treatment:

Patients with acute hepatitis A usually require only supportive care, with no restrictions in diet or activity. Hospitalization might be necessary for patients who become dehydrated because of nausea and vomiting and is critical for patients with signs or symptoms of acute liver failure. Medications that might cause liver damage or are metabolized by the liver should be used with caution among persons with hepatitis A.
