Chickenpox is often considered a fairly harmless disease. However, before the varicella vaccine was routinely given, chickenpox infections resulted in over 10,000 hospitalizations and 100-150 deaths each year in the United States alone. That’s about two or three deaths a week.
Hepatitis A is not as common in the US as it is in the rest of the world, but outbreaks still occur. Until 2004 hepatitis A was the most frequently reported type of hepatitis in the US and more common in Oregon than most other states.
