Hepatitis A

Hepatitis A is also called infectious hepatitis type A. It is a viral infection that infects the liver.
 

Where are you at risk of becoming infected with Hepatitis A?

Hepatitis A is most often transmitted via food contaminated with faeces.

Among other things, hepatitis A can be transmitted via contaminated food or drinking water, and you are particularly exposed to hepatitis A infection if you are in a part of the world where hygiene may be less good. 

Hepatitis A can also be transmitted through sexual contact, primarily in the form of anal sex.

In general, a person who has hepatitis A is most contagious at the beginning of the disease, and you can be contagious before the onset of symptoms. 

In addition, oysters, clams and other shellfish harvested in water contaminated with sewage may also contain the hepatitis A virus. You can thus become infected with hepatitis A if you eat raw shellfish. Viruses are destroyed by heat treatment. In Denmark, outbreaks of hepatitis A have been seen after consumption of contaminated fruit and fresh berries.

Which areas are found Hepatitis A | Contagious Hepatitis?

Most cases of hepatitis A occur during travel to countries in Africa, South America and Asia. 

What symptoms can be seen in infection with Hepatitis A?

Most people, and especially children who get Hepatitis A, often have a mild course of the disease with symptoms such as:

  • nausea

  • fever

  • abdominal pains

  • joint pain

  • diarrhea

  • fatigue

Some may develop more pronounced symptoms such as:

  • jaundice (yellowing of the skin and the whites of the eyes)

  • dark urine

  • light stools

On average, the incubation period (the time from infection to the appearance of symptoms) is 28 days.

Age is important for whether you develop symptoms. Most children under the age of five do not develop symptoms of hepatitis A, while most adults over the age of 50 are at greater risk of developing symptoms and severe disease.

After the illness with hepatitis A is over, you are immune for life.

What treatment is available for Hepatitis A?

There is no specific treatment for hepatitis A infection. 

How is Hepatitis A prevented?

How do you get vaccinated against Hepatitis A?

The hepatitis A vaccine protects against hepatitis A. It lasts for at least 30 years after 2 doses. The second vaccination must be given at least six months after the first vaccination. 

The first dose can be given up to departure and provides almost 100% protection for five years for adults.
