Being vaccinated against hepatitis A helps to produce antibodies to the virus. A complete course of vaccination requires 2 injections, given 6 months to 12 months apart. The body takes 4 weeks to develop antibody against hepatitis A after the first vaccine injection. Hepatitis A vaccine is not licensed for children younger than one year of age.
Hepatitis A is a liver disease caused by the Hepatitis A Virus. It has an incubation period usually 14-28 days.
Transmission: In general, it is transmitted through fecal-oral route. Food contaminated with the virus is the most common vehicle transmitting hepatitis.
- Eating contaminated food without proper cooking, especially bivalve shellfish like oysters, clams, scallops and mussels, etc.
- Drinking contaminated water
- Close personal contact with infected person
Effects:
Affected persons may be asymptomatic. Those who have symptoms may have:
- mild fever
- tiredness
- muscle pain
- headache
- loss of appetite, nausea, vomiting, diarrhea, upper abdominal pain
- jaundice (yellow discoloration of skin and eyes) and tea-coloured urine
Not everyone who is infected will have all of the symptoms. Adults have signs and symptoms of illness more often than children, and the severity of disease increases in older age groups. Recovery from symptoms following infection may be slow and may take several weeks or months.
Hepatitis A infection does not cause chronic liver disease and is rarely fatal, but it can cause debilitating symptoms and fulminant hepatitis (acute liver failure), which is associated with high fatality rates.
More Facts:
The hepatitis A virus (HAV) is transmitted through ingestion of contaminated food and water or through direct contact with an infectious person.
Almost everyone recovers fully from hepatitis A with a lifelong immunity. However, a very small proportion of people infected with hepatitis A could die from fulminant hepatitis.
WHO estimates that hepatitis A caused approximately 7 134 deaths in 2016 (accounting for 0.5% of the mortality due to viral hepatitis).
The risk of hepatitis A infection is associated with a lack of safe water, and poor sanitation and hygiene (such as dirty hands).
