This assignment answers the following questions –
1. Using a traditional agent–host–environment triad approach for describing the public health aspects of infectious diseases,explain the basic scientific features of the origin, propagation, transmission, and infection of humans by Cryptococcus gattii.
2. Discuss the extent to which the agent–host–environment triad approach to public health control measures for preventing the spread of Cryptococcus gattii to humans is likely to be sufficient or insufficient for the effective control of this hazardous infectious agent in Canada.
3. Describe how an ecosystem approach to understanding and controlling Cryptococcus gattii in Canada might differ from the more traditional agent–host–environment triad approach. Discuss the extent to which the ecosystem approach to public health control measures for preventing the spread of Cryptococcus gattii to humans is likely to improve the effectiveness of public health control measures for this hazardous infectious agent in Canada.
4. Describe how large scale environmental factors such as globalization, climate change, and environmental land use may have influenced the onset of Cryptococcus gattii infections in Canada and/or the United States. What public health lessons can be learned from this experience?
Description
The health of ecosystems that we live in is crucial to our own health and well being. Urbanization, globalization, deforestation, global warming, climatic shifts etc. are cause irreversible damage to the ecological systems. The outbreak of Cryptococcus gattii in the western regions of Canada is the result of this ecological imbalance. This paper analyses the origin, behavior and diseases caused by the fungus. The paper analyses the outbreak with traditional agent, host and environment triad model. The paper also tries to understand the root causes that might have caused the outbreak. The paper then compares the efficacy of agent, host and environment model with ecosystem model solution to the issue.
