What are the 4 types of disease transmission?

The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle. The portal of entry is the means by which the infectious microorganisms gains access into the new host. This can occur, for example, through ingestion, breathing, or skin puncture.

What is the difference between transmission and infection?

The crux of the distinction is this: contagious diseases are spread by contact, while infectious diseases are spread by infectious agents.

What are three methods of disease transmission?

Modes of transmission
- Direct. Direct contact. Droplet spread.
- Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
  
  Is mode of transmission by kissing?
