Vector-Borne Transmission

Vectors

A. Examples (MFT)

1. Mosquitoes

2. Fleas

3. Ticks

B. Types of Transmission (MB)

1. Mechanical Transmission

• Vectors carry infectious agents on their bodies or in their guts without alteration.

• Examples (SY):

  • Flies carrying Shigella on appendages.

  • Fleas carrying Yersinia pestis (causative agent of plague) in the gut.

2. Biological Transmission

• Infectious agents undergo maturation in an intermediate host before transmission to humans.

• Examples (MG):

  • Malaria

  • Guinea worm disease
