Thank you for writing.
You can read about Hep A, B and C on the following link (cut and paste and click on the links on the left hand side to learn about each kind of hepatitis): https://www.empowher.com/condition/hepatitis
Are you saying you have a diagnosis of Hep A?
This virus is usually found in the stool (feces) of people who have the infection. It is spread by:
Putting something in your mouth that has been infected with the hepatitis A virus
Drinking water contaminated by raw sewage
Eating food contaminated by the hepatitis A virus, especially if it has not been properly cooked
Eating raw or partially cooked shellfish contaminated by raw sewage
Sexual contact with a partner infected with the hepatitis A virus, particularly anal sex
Risk factors for hepatitis A include:
Having close contact with an infected person although the virus is generally not spread by casual contact
Using household items that were used by an infected person, but were not properly cleaned
Having sex with multiple partners
Having sex with a partner who has hepatitis A
Traveling to or spending long periods of time in a country where hepatitis A is common or where sanitation is poor
Injecting drugs—especially if you share needles
Working as a childcare worker, changing diapers or toilet training children
Being in daycare centers
Receiving plasma products (such as people with hemophilia)
Your Hep A may be a recent infection or your were not tested for it before. Blood tests specify what a doctor is looking for.
As to RA - it can be quite difficult to diagnose for some. Were you sent to an RA specialist by a regular doctor? What tests were done?
I doubt anyone is lying to you on purpose - rather, there is an issue with communication problem between your care-givers. Request a meeting with your primary care physician so everything can be explained to you properly.
