Question 12

Question 13

Answer 13

Abnormal state where the body is not capable of performing normal function

Question 14

Question 17

A disease that spread from one host to the other is called

Answer 17

A communicable disease

Question 18

Incubation

Answer 18

Time between infection and first signs and symptoms

Question 19

Prodromal period

Answer 19

Early mild symptoms

Question 20

Period of illness

Answer 20

Most severe signs and symptoms

Question 21

Period of decline

Answer 21

Signs and symptoms subsided
Patient is still vulnerable to secondary infection
Can last hours and days

Question 22

Period of convalescence

Answer 22

Recovery occurs
The pathogen can still be spread from patients to others
Can carry pathogen for years and months

Question 23

Duration of symptoms

Answer 23

Acute
Chronic
Latent

Question 24

Acute

Answer 24

Rapidly developing and slow duration e.g influenza

Incubation period - period of illness- convalescence
Acute illness is short term cause pathogen is eliminated by the host defenses; person is usually immune to reinfection

Question 25

Chronic

Answer 25

Chronic is slow to develop and continual duration e.g tuberculosis

Incubation—illness (long lasting)
Chronic; illness persists over a long period of time

Question 26

Latent

Answer 26

Inactive for a period of time and can be reactivated e.g cold sore herpes

Incubation- illness period-convalescence-latency- recurrence

Latent;illness may reoccur if immunity weakens
