(some things can be spread by more than 1 I)
2
Q

What is direct inoculation?

A

Skin or mucous membrane comes into contact with the skin or mucous membrane of an infected person

3
Q

What is indirect inoculation?

A

Skin or mucous membrane comes into contact with a contaminated surface

4
Q

What is the chain of infection?

A

Pathogenic microorganism - reservoir - means of escape - mode of transmission - means of entry - host susceptibility
*breaking the chain at any point interrupts transmission

5
Q

Where is the reservoir of ebola?

A

Fruit bats in africa

6
Q

What are the 2 categories of control of infection precautions and what do they mean?

7
Q

What are the 3 types of transmission based precautions?

A

Contact precautions
Droplet precautions
Airborne precautions

8
Q

What are the 10 standard control of infection precautions?

A
Hand hygiene
Sharps management
Clinical waste
PPE
Patient placement
Body fluid spillages
Environmental cleanliness
Clean equipment
Laundry
Respiratory etiquette
9
Q

What are WHOs 5 moments of hand hygiene?

A
Before patient contact
Before aseptic task
After body fluid exposure risk
After patient contact

17

A

No

19
Q

What is the difference between morbidity and mortality?

A

Mortality refers to the number of people who have died in a population where as morbidity refers to the number of people who are diseased

20
Q

Equation for mortality rate?

A

No of deaths / population at risk X 1000

21
Q

What is the crude death rate?

A

Mortality rate for the whole population

22
Q

What does the standardised mortality rate do?

A

Compares the expected rate with the observed rate

23
Q

What is the difference between incidence and prevalence?

A

Incidence is the number of new cases diagnosed in a population where as prevalence refers to the number of people in a population who have the disease at a set time

24
Q

Incidence rate equation?

A

Number of new cases of a disease occurring in a population during a specific period time / number of persons exposed to risk of developing the disease during that period of time (usually expressed per 1,000)

25
Q

Prevalence rate equation?

A

Number of cases of a disease present in a population at a specific point in time / number of persons at risk of having the disease at a point in time (usually expressed per 1,000)

26
