Hepatitis is inflammation of the liver. Viruses usually cause it, but toxins, parasites or drug and alcohol abuse can also lead to hepatitis. In Washington, hepatitis A, B and C viruses are the most common causes.
People living homeless are at greater risk for hepatitis A. View this flyer for more information.
