Vehicle is the agent that may indirectly transmit an infectious agent include food,water,biologic products (eg: blood), formites. Vehicle transmission occures when substance like soil,water,air carries infectious substance to a new host.
A vehicle may carry pathogens passively. For eg: food or water may carry hepatitis A virus.
A vector is any agent that that carries and transmits an infectious pathogen in to another living organism. Vector transmission occures when a living organism carries an infectious agent on its body to new host.
Example include dengue fever,malaria,Lyme disease
Other modes of transmission include:
1. Contact transmission: It may be Direct or indirect
Contact transmission occures when pathogens are transmitted between the individuals without an contaminated intermediate person or object
Indirect transmission occures when there is contaminated intermediate person or object
2. Respiratory transmission: occures due to the inhalation of droplets with size greater than 5 microns. It is generally limited within three feets of surface
3. Airborne transmission: it is also a type of respiratory transmission due to inhalation of droplet nuclei with size ranging from 1-5 microns.
