1

Who is more susceptible to infectious disease?

older people

2

Characteristics of aging with infectious disease

- changes in immunity
- reactivation of dormant infections
- skin changes
- diminished reflexes
- prone to pneumonia
- fever

3

What types of dormant infections can be reactivated with aging?

- herpes zoster (chickenpox)
- TB

4

______ skin is more easily damaged

atrophic

5

Which reflexes are diminished with aging?

- cough
- gag

6

Why are older people more prone to pneumonia?

decreased bronchiolar elasticity

7

Why might fever not be a reliable sign of infectious disease for older adults?

lower basal body temp

8

A temp of _____ may signal infection for older adults

99-100

9

What is an infection?

organism establishes a parasitic relationship with the host

10

Immune response is produced by an organism through these:

- invasion
- multiplication

11

How does the immune response from an infection cause injury to the host?

- toxins from microorganisms
- tissue/cell death of the host

12

colonization

- microorganisms present in tissue
- don’t create systemic disease

13

colonized carrier/transmitter s/s

may not have s/s

14

Development of an infection depends on these:

1. transmission mechanism
2. proper environment
3. susceptibility of the host
4. pathogen may contaminate body surface and be destroyed by first line defenses

15

What does an elevated titer indicate?

- antibody against antigen
- no antibiotic necessary
- infection control to prevent spreading

16

What is the characteristic of a clinically apparent infection?

host injury with s/s

17

Ebola comes from these sources

- fruit bats
- monkeys
- person to person through secretions

18

Ebola: time from invasion to s/s

2-21 days

19

What is a latent period?

microorganism has replicated and is dormant

20

What is the period of communicability

time after latency where symptoms or transmission can occur

21

Ebola: period of communicability

after symptoms occur

22

How can a causative agent be passed with communicable diseases?

- directly
- indirectly
