Life Cycle and Transmission of Guinea Worm Disease
Review the attached schematic for the life-cycle and transmission of Guinea Worm.
- What is the infectious agent for Guinea Worm?Please name it and describe (is it a virus, bacteria etc.). Briefly describe it’s life-cycle.
- Outline the chain of infection by identifying the reservoir(s), portal(s) of exit, mode(s) of transmission, portal(s) of entry, and factors in host susceptibility.
- Reservoirs:
- Portals of exit:
- Modes of transmission:
- Portals of entry:
- Factors in host susceptibility:
- Can the infectious agent continue without a human host?Why or Why not?What else is required for the infectious agent to complete its life-cycle?
- Develop public health strategies to prevent Guinea Worm Disease in the human population.Hint – look at each link in the chain of transmission and see if you can break the chain!Provide one strategy for a-e above, or explain why there is no strategy for that link in the chain.
