Hepatitis A is a disease that cause damage to the liver, formally known as infectious hepatitis. It can be transmitted through fecal-oral route. Millions are infected each year by Hepatitis A. Some symptoms are fatigue, fever, abdominal pain, nausea, and appetite loss.
Drugs given orally enter the body by way of traveling through the mouth and into the GI system. Drugs given parenteraly enter through the blood stream (IVs, for example) and act within the body must faster than those given orally. There is a higher risk for infection or complication with parenteral administration than with oral.
Hepatitis A is not a sexually transmitted disease. Most other forms of Hepatitis ARE sexually transmitted, but Hepatitis A is NOT. Hepatitis A is transmitted through the "fecal-oral" route. It is most often transmitted in foods when food preparers who have Hep A don't wash their hands carefully before preparing food.
The parenteral route of infection occurs when an organism gets access to the tissues underneath the mucous membranes or the skin. Punctures, injections, bites, cuts, wounds, surgery and split skin or mucous membranes (from swelling or dryness) are all examples of parenteral routes of infection. Source: Tortura, Funke, Case.

Small volume parenteral products are packaged into containers smaller or equal to the volume of 100mL. They are packaged in vials, ampoules, prefilled syringes, and read-to-mix systems. It si common for small volume parenteral products to be injected via the intravascular, intramuscular, or subcutaneous route. These parenteral products must be sterile and free of pyrogen and particles.
Hepatitis A is an infectious viral disease. It is spread via the fecal-oral route.
