About Hepatitis A (Hep-Ah-Ty-Tiss)
What is Hepatitis A?
How is Hepatitis A transmitted?
Why should I take the Hepatitis A vaccination?
Many cases of travel-related Hepatitis A occur in travelers to developing countries. While they are much less in developed countries, community-wide outbreaks may still occur. The risk for infection increases with duration of travel and is highest for those who live in or visit rural areas, trek in back-country areas, or frequently eat or drink in settings of poor sanitation.
Currently, there is no specific treatment available for persons with Hepatitis A. As Hepatitis A is one of the most common vaccine-preventable infections acquired during travel, we highly recommend the vaccine to be taken.
Points to Note:
Laboratory diagnostic tests are not perfect and are not 100% accurate
- We do not have a test for every disease or virus but most of those pathogens that are of public health importance or have long term implications on your health can be tested
- No one single test can be used with absolute certainty to diagnose a disease. Often, we depend on a combination of tests to make a diagnosis
- Sometimes, we have to resort to trial treatment or empiric treatment if investigative tests are inconclusive. If the patient makes a therapeutic response and feels better, we have achieved our goal
- In PUO, we are looking for treatable causes and to rule out sinister causes eg. malignancies so that we do not miss opportunities for early treatment or intervention
