All the following are modes of transmission of rabies, EXCEPT:
Person to person transmission
Aerosol
Ingestion of products made from infected animals
Licks
Aerosol transmission may occur in caves harbouring rabies infected bats. Person to person transmission is also on record. Eg - an infected child biting its parent. Ingestion of the virus is not believed to transmit the disease as the virus would be destroyed by stomach acid/enzymes. Ref: Park, Edition 21, Page 252
