Group 3: Monthly Reported Diseases
- Cont. Viral Hepatitis

Reservoir

Type A: Humans, rarely chimpanzees and other primates.
Types B and C: Humans. An animal reservoir in nature has not been recognized.
Type E: Man is the natural host; some non-human primates, e.g. chimpanzees. Natural infections have been described in pigs, chicken and cattle, particularly in highly endemic areas.

3.1.5 Mode of transmission

Types A and E: Person-to-person by the fecal-oral route. Common source outbreaks related to contaminated water; food contaminated by infected food handlers, including foods not cooked or handled after cooking; raw or undercooked mollusks harvested from contaminated waters; and contaminated produce such as lettuce and strawberries. Hepatitis E may in fact be a zoonotic infection with coincident areas of high human infection.
