Mode of Transmission of Rabies

Mode of Transmission of Rabies.

People are infected following a deep bite or scratch by an infected animal. Dogs are the main host and transmitter of rabies. They are the source of infection in almost all the rabies deaths annually in Asia and Africa.

Bats are the source of most human rabies deaths in the United States of America and Canada. Bat rabies has also recently emerged as a public health threat in Australia, Latin America and western Europe. However in these regions the number of human deaths due to bat rabies remains small compared to deaths following dog bites.

Transmission can also occur when infectious material - usually saliva - comes into direct contact with human mucosa or fresh skin wounds. Human-to-human transmission by bite is theoretically possible but has never been confirmed.
