ABSTRACT
This research was performed to determine the factors of the food-borne illness Hepatitis, specifically the hepatitis A virus (HAV). It explained how HAV can be transmitted most commonly through person-to-person contact and provided examples of outbreaks that have occurred in the United States within the last 20 years.
