final questions Flashcards
Why can humans be considered ‘parasitic bodies’?
Humans are considered parasitic bodies because they host 90 trillion microbes - these microbes are essential for survival
What is Koch’s Postulate and germ theory? What is the significance of the germ theory in biomedicine and public health?
- Koch’s Postulate & germ theory (1891) isolated microorganisms as a cause of illness
- Biomedical approach - reduced the complexity of illness to a singular causative factor, reliance on empirical evidence
- Three interacting factors - pathogen, host, & environment
List the types of pathogens
Virus, bacteria, protozoa, fungi, worms, & prions
What are the factors that cause pathogens to emerge?
Demography & behaviors, ecological changes (natural and human-driven), globalization (travel and commerce), microbial adaptations (human population immunity), & public health infrastructure
What are the two types of disease transmission and how do they work?
Direct transmission (host-to-host) and vector transmission (host to intermediary to host)
What is the epidemic curve?
Life course of infection prevalence in a population - ‘flatten the curve’
Infected, immune (prior infection and/or vaccination), dead
What is the difference between isolation and quarantine?
- Isolation - separation of sick person (individual isolation of symptomatic patients, community isolation of individuals NOT symptomatic)
- Quarantine - geographical separation of populations potentially exposed
What are the primary conditions for isolation and quarantine?
Knowledge of disease, vector of transmission (water, air, etc), contagiousness, severity of disease (morbidity and mortality), temporality (permanent or treatable - transmission), moral panic (fear outweighs threat)
What is the relationship between colonialism and infectious disease?
Colonialism increases infectious disease. As colonizers infiltrate
What are the health legacies of colonialism?
What are the major global epidemiological transitions?
What is the McKeown Hypothesis?
What is the Global Polio Eradication Initiative?
- Goal: total eradication of the polio virus, one of the largest coordinated global health projects in history
- Example of a vertical campaign
What are some of the major reasons for vaccine hesitancy?
Religion/spiritual beliefs, history and politics (colonial/imperial legacies, biomedical health practitioners as representatives), health systems (inclusions and exclusions of health campaigns), health delivery (existing (dis)trust of practitioners)
In the Closser article, what are some of the major findings regarding global vaccine hesitancy, and vertical approaches vs. other public health approaches
- Discourses about vaccines are both local and shaped by global forces
- Vaccine refusal is shaped by contrast between rigorous vertical campaigns (how many/year can define this) in the absence of public health infrastructure (or no improvement)
- Shaped by pre-existing trust in those who administer vaccines
- Lack of holistic approach hurts vertical approach to disease eradication
