Hepatitis A is an inflammatory disease of the liver caused by the hepatitis A virus (HAV). It can easily be transmitted through contaminated food, water and surfaces as virus is highly resistant to chemicals and the environment.

The virus can survive several hours on fingers and months on frozen fruits. Most people thought hepatitis A and B are related in terms of their medium of transmission. The fact is hepatitis B can only be transmitted via body fluids through sexual contacts or from contact with contaminated blood from infected person.

Hepatitis A can only be diagnosed through a blood test. Its symptoms include fever, malaise, nausea and vomiting, diarrhea, abdominal pain, dark urine and jaundice (yellowing of skin). Recovery usually takes a few months. There is no specific treatment for hepatitis A. So far vaccination is the most effective defense against it.

Its symptoms include fever, persistent headache, ‘melon juice’ diarrhea that is sometimes preceded by constipation and abdominal cramps. If left untreated, there is a 12% to 33% chance that the disease could be fatal.

Antibiotics treatment proves to be difficult due to the increasing number of antibiotic-resistant strains. Therefore, immunization such as vaccination is the most effective defense against TF. Besides, proper hygiene practice is also very important in TF prevention.


Traveler’s diarrhea is the most frequent disease that most travelers get infected with. Around 20% to 50% of international travelers or an estimated 10 million people develop traveler’s diarrhea.
