What are the 5 intrinsic factor to perpetuate an infectious agent?
|
- mutation
- switching of genes (access to gene pool) - host populations - transmission - multiple hosts (zoonosis) |
|
What are the 4 ways to access gene pool?
|
- transformation
- conjugation - gene capture - reassortment (influenza) |
|
Describe the 3 types of host populations
|
- low density hosts (require to keep host alive)
- high density hosts (many options, can kill host) - naive population (those without immune response to agent) |
|
What are the 8 human factors in emerging diseases?
|
1) public health (sanitation)
2) urban centers (high density, naive pop) 3) human behaviors (sex, drugs, diet) 4) warfare (inability of infrastructure to survey pop) 5) ecological changes (closer to animal environment, exposure to new diseases) 6) international travel 7)technological and Industrial influences (cooling/heating, food prep, industrial agriculture) 8) commerce (buying exotic pets, transporting livestock, international trade) |
|
What are the 4 steps to the CDC disease containment strategy?
|
1) surveillance (gene sequencing)
2) applied research (public health initiatives) 3) prevention and control 4) infrastructure (ability to make, store, distribute meds) |
|
What are the 6 characteristics that make an agent ideal for eradication?
|
1) small number serotypes
2) no animal reservoir 3) prompt Ab response 4) easily clinically id 5) no carrier/subclinical infections 6) no vector |
