  • infectious diseases
  • chemicals and poisons

  • emergency response
  • environmental hazards

2

Reproductive number

 

  • Transmission potential of a disease
  • Average number of secondary infections arising from one primary infection

3

R0

basic reproductive number- assumes a population where everyone is susceptible

4

R

effective reproduction number- acknowledges some immunity among a population e.g. through vaccines or prior infection

- this immune propriton of a population is X

so R= R0X

5

herd immunity threshold (HIT)

6

Notifiable disease

 

  • Statutory legal responsibility to notify PHE of notifiable disease and other situations with public health implications
    • ‘reasonable ground for suspecting’ a disease/illness (don’t wait for confirmation) e.g. if meningitis is a main differential
    • Urgent issue should be notified within 24 hours

7

sensitivity

Sensitivity- how good a test is at detecting cases

8

Specificity

- how good a test is at detecting non-cases

9

response phases

10
