F3: Health

F3: Diffusion of disease

The merits of prevention and treatment in managing disease, including social marginalization issues, government priorities, means of infection and scientific intervention

As you watch the videos, consider:

  • Power: the ways to prevent and treat the disease
  • People: who would be most affected (+ and - )
  • Possibilities: What options are there to prevent future outbreaks?
  • Place: Spatial disparity in health and access to treatment and prevention

Discussion: Let's discuss these question while using as many examples as possible.

  • What is the difference between prevention and treatment?
    • What are each one's merits and drawbacks?
  • What parts of a community are more likely to receive proper treatment?
  • How are women more vulnerable to certain diseases?
  • What measures could be used to prevent diseases of poverty?
  • How can governments implement disease prevention policies?
    • What about treatment?
    • Which should they prioritize?
  • How can a governments respond to a highly contagious disease outbreak?
    • The WHO?
    • The medical and scientific community?
  • What are the different roles of international organizations such as World Health Organization, governments and NGOs in combating disease.

Geographic factors contributing to the incidence, diffusion and impacts (demographic and socio-economic) of vector-borne and water-borne diseases

Part 1. One detailed example of a vector-borne disease: Malaria

    • Read N&C p. 296 - 300 and this BBC article (highlights on my Diigo)
    • Have a look at the Shrinking Malaria Map
    • Take detailed notes
      • Malaria: Causes and symptoms
      • Demographic factors contributing to incidence, diffusion and impact
      • Socio-economic factors contributing to incidence, diffusion and impact
      • Answer questions from Activity 15 on p. 300
    • Have a good understanding of the Malaria crisis, as well as prevention and treatment initiatives in Nigeria
      • more information on my Diigo library #Malaria and #Nigeria

Part 2: Water-borne diseases: Cholera

Managing pandemics, including the epidemiology of the disease, prior local and global awareness, international action and the role of media

One case study of a contemporary pandemic and the lessons learned for pandemic management in the future

  • Pandemic: (of a disease) prevalent over a whole country or the world
  • Epidemiology: the branch of medicine which deals with the incidence, distribution, and possible control of diseases and other factors relating to health.

In groups, each of you will research one of the following sections and present your findings to the class:

When relevant:

    • Use maps and visuals
    • Use concrete examples (Haiti and/or others)
    • Emphasize the 4Ps
    • Suggested sources:
      • WHO
      • N&G p. 300-302
      • My Diigo library #Cholera and #Haiti

Group 1:

    • Give a brief description of Cholera, it's epidemiology (incidence (current and over time), means of diffusion, global distribution, known cures and preventive measures) main causes and symptoms
    • Explain and give a brief history of Cholera's 7th/current worldwide pandemic

Group 2:

    • Describe the 2010 Haiti earthquake and its consequences on the Haitian population
    • Describe prior local knowledge of Cholera in Haiti
    • Explain the spread, causes and consequences of the ensuing cholera outbreak
    • What lessons were learned about the Haiti outbreak for future (worldwide) interventions?

Group 3:

    • Using specific examples, describe and evaluate the international management strategies (prevention and treatment) of Cholera in the 21st century by affected governments, the WHO and specific NGOs (MSF) to combat the pandemic
    • Describe the global awareness of the disease
    • Evaluate the role of media in spreading awareness for the disease
