Modes of Transmission

The way an infectious disease is spread

• Transmission

• Translation

• Emission

• Direct Contact

• Indirect Contact

Pathogens transmitted via contaminated food or water.

• Direct Contact

• Indirect Contact

• Airborne Transmission

• Foodborne Tranmission

• Vector-Borne Transmission

Which are three types of DIRECT transmission (of diseases)?

• Body fluid exchange

• Skin contact

• Sneezing/ coughing

• Fomite transfer

• Airborne pathogens

Mosquitos, ticks and flies are all examples of :

• Fomites

• Vectors

• Viruses

• Environmental Reservoirs

Explain the difference between direct and indirect modes of disease transmission. Direct is actual touch from vector to host and indirect means the host picks up the disease from an object or other organism.

• Direct transmission occurs through kissing, while indirect transmission occurs through hugging

• Direct transmission occurs through sharing food, while indirect transmission occurs through sharing utensils

• Direct transmission occurs through direct physical contact, while indirect transmission occurs through intermediary objects or organisms.

• Direct transmission occurs through the air, while indirect transmission occurs through water

• hairbrushes

• sneezes

• flies
