Pathogen & Disease Test: How to Prevent the Spread of Disease

Question 1

What factors can influence the spread of an infectious disease?

Answer 1

• social climate
• environment
• diet
• general health
• access to medical care

Question 2

How can we control the spread of disease?

Answer 2

1. Adopting Safe Behaviours
2. Cleaning up the Environment
3. Medical Care/ Treatment
4. Immunization

Question 3

Behavioural Control

Answer 3

transmission of disease can be prevented or significantly reduced by adopting safe behaviours:

• using condoms
• isolation/quarantine when ill
• appropriate personal hygiene practices (washing hands)
• cough into elbow not hands
• stay home if you are feeling unwell

Question 4

Cleaning/Modifying the Environment

all pathogens require certain conditions for growth, reproduction and transmission. By modifying the environment to make it less suitable for pathogens, most infectious diseases can be controlled:

• development of effective sanitation and sewage treatment
• treatment of drinking water
• spraying drainage ditches
• draining swamps to eliminate breeding sites for mosquitos
• using larvacides and insect repellant
• spraying disinfectants to sterilize potentially contaminated surfaces

Question 5

Medical Care

Answer 5

• immunization schedules (creates “herd immunity”)
• following aspetic and sterilization techniques ( disinfectants for objects/surfaces and antiseptics on living tissue)
• autoclaving medical instruments and biohazardous waste
• PPE
• treating those that are ill
