Epidemiology Flashcards
1
Q
Transmission Basic reproductive number
A
R0 = BxCxD B = probability of transmission, C= exposure rate of susceptible partners, D= duration of infectious period
2
Q
Transmission Basic reproductive number
A
R0>1 -> epidemic, goal control R0<1
3
Q
Transmission B Probability of transmission
A
Infectivity (viral or bacterial load), biological interactions with other organisms, behaviours which increase/decrease risk (condom, anal vs vaginal intercourse
4
Q
Transmission C Behavioural parameters
A
Rate of partner change, patterns of sexual mixing (gender, age, assortative (serosorting), disassortative (age gap)
5
Q
Transmission D Duration
A
Infectious period of organism, treatment seeking behaviour
