Hepatitis A

By Colin Wei


Pain in the abdomen, joints, and muscles, fatigue, loss of appetite, fever, diarrhea, vomiting, nausea, dark urine, itching, yellow skin and eyes, weight loss. Children who have the disease have less symptoms. The virus doesn't cause long term conflicts. 10 to 15 % of people with hepatitis A will have symptoms that come back to them in a 6 to 9 month period.


Hepatitis A is caused when a person eats food contaminated by someone with virus, drinks contaminated water, or eating raw shellfish from water polluted sewage. You can catch the disease if you drink water or food that's been contaminated by someone with the virus. If you eat a food that has been contaminated, you could get it.

Immune Cells

Hepatitis A is contagious and the immune system takes a long time to attack virus. Once the body senses intruder, the immune system attacks. The virus has the ability to evolve so it is hard to fight.


This virus replicates inside the cytoplasm of the infected people. After the virus enters the host cell, the virus loses its capsid and the uncoated RNA induces the host cell to produce the viral polyprotein. This does not shut off the protein synthesis of the cell. Among the viral proteins there is a protease for the synthesis of structural proteins. Polymerase for the replication of viral RNA becomes rapidly encapsidated into new viruses.


This can be treated in one or two months. Get a lot of sleep and make sure to drink a lot of water. Avoid alcohol and there is a vaccine for it too.


There is a two dose vaccine to treat the vaccine and there is no treatment.
