By: Jadon Guthrie

Symptoms of Hepatitis A:

  • Fatigue
  • Nausea
  • Abdominal Pain
  • Loss in Appetite
  • Low-Grade Fever

Causes of Hepatitis A:

  • Consuming contaminated food or water.
  • Coming into contact with an infected individual.

Immune Cells Involved in Immune Response:

Liver cells will rid the body of this virus within 6 months.

Replication of Hepatitis A:

After the entry of the virus into the host cell, the virus loses its capsid and the uncoated RNA induces the host cell to produce the viral poly-protein without shutting off the protein synthesis of the cell.

This would be considered a virus that replicates with the Lytic Cycle.

Treatment of Hepatitis A:

No treatment exists for Hepatitis A. The disease will naturally be treated by the liver cells within 6 months of contraction. Some ways to help symptoms while infected is to rest, cope with nausea, and to give your liver a break.

Prevention of Hepatitis A:

As holds true for many viruses, Hepatitis A is preventable through vaccination. In areas with Hepatitis A outbreaks, it is best to keep hands clean at all times, and wash any fruits or vegetables. Also, in Hepatitis A stricken areas, it is best not to consume under cooked meat and to use only bottled water for drinking and everyday tasks in order to prevent the virus.
