Epidemiology of enteric diseases

The video explains the differences between direct and indirect transmission of enteric viruses. Hepatitis E virus exemplifies both mechanisms.

Enteric viruses are resistant viruses that may withstand the harsh conditions of the gastrointestinal tract. They may be eliminated unaltered with the faeces and be transmitted directly (for example, when a dog sniffs the faeces of another dog) or indirectly (when water, food or inanimate objects become contaminated before entering the body).
