Answer 1

Question 2

What is the burden of Infectious Disease in the UK?

Answer 2

Question 3

What is the social and economic impact of COVID - 19

Answer 3

Question 4

What are Zoonotic Diseases?

Answer 4

Question 5

Answer 5

Question 6

What is the “one health” concept?

Answer 6

The health of humans, animals, and ecosystems are closely interlinked. Changes in these relationships can increase the risk of new human and animal diseases developing and spreading.
The close links between human, animal and environmental health demand close collaboration, communication and coordination between the relevant sectors.
One Health is an approach to optimize the health of humans, animals and ecosystems by integrating these fields, rather than keeping them separate.

Question 14

Answer 14

Question 15

What is

Point Source

Continuous source

Propagated sourse

Intermittent Source

Answer 15

Question 16

What type of outbreak would produce this curve?

Continuous
Intermittent
Point
Propagated

Answer 16

Point source curve

Question 17

What type of outbreak would produce this curve?

Continuous
Intermittent
Point
Propagated

Answer 17

Continuous Curves

In a continuous source exposure is not confined to one point in time (prolonged over a period of days, weeks or longer); as such, cases are spread over a greater period of time depending on how long the exposure persists

Question 18

What type of outbreak would produce this curve?

Continuous
Intermittent
Point
Propagated

Answer 18

Intermittent

An intermittent source curve is similar to continuous but exposure is intermittent; multiple peaks – length: no relation to the incubation period (reflects intermittent times of exposure) e.g., contaminated food product sold over period of time
