Understand the causes, prevention and control of infection
This element equips learners with essential knowledge on the causes and transmission of infection, and the practical measures required to prevent and control its spread in health and social care settings. It emphasises the importance of risk assessment, correct use of PPE, good personal hygiene, and understanding roles and responsibilities to maintain a safe environment for service users and staff.
Assessment criteria
Topic Overview
The BIIAB Level 2 Diploma in Health and Social Care (Northern Ireland) provides a foundational understanding of the principles and practices within the health and social care sector. This qualification covers essential topics such as communication, equality and inclusion, duty of care, safeguarding, and person-centred approaches. It is designed for those starting their career in care settings like residential homes, day centres, or domiciliary care, and it aligns with the standards set by the Northern Ireland Social Care Council (NISCC).
Studying this diploma equips you with the knowledge to support individuals with their physical, emotional, and social needs while promoting their independence and dignity. The curriculum emphasises the importance of working within legal and ethical frameworks, including the Mental Capacity Act (Northern Ireland) 2016 and the Safeguarding Vulnerable Groups (Northern Ireland) Order 2007. By mastering these concepts, you will be prepared to deliver safe, compassionate care and contribute effectively to multidisciplinary teams.
This qualification is a stepping stone to further study, such as the Level 3 Diploma in Health and Social Care, or direct employment in roles like care assistant or support worker. It also fosters transferable skills like empathy, teamwork, and problem-solving, which are vital in any care environment. Understanding this diploma's content is crucial for providing high-quality care that respects individual rights and promotes well-being.
Key Concepts
Core ideas you must understand for this topic
- →Person-centred care: Tailoring support to an individual's preferences, needs, and values, ensuring they are active partners in their care planning.
- →Safeguarding: Protecting vulnerable adults and children from abuse, neglect, or harm, following policies like the Adult Safeguarding: Prevention and Protection in Partnership (NI) 2015.
- →Duty of care: A legal obligation to act in the best interest of individuals, balancing their safety with their right to take risks.
- →Equality and inclusion: Ensuring everyone has equal access to care and is treated with dignity, respecting diversity in age, disability, gender, race, religion, and sexual orientation.
- →Effective communication: Using verbal and non-verbal methods to build trust, understand needs, and provide clear information, including active listening and appropriate language.
Learning Objectives
What you need to know and understand

Understand the importance of risk assessment in relation to the prevention and control of infections5.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately identifying common pathogens (bacteria, viruses, fungi) and explaining how they cause infection.
- Award credit for clearly describing transmission routes (direct, indirect, airborne, droplet) with appropriate examples from care settings.
- Expect learners to outline their own responsibilities for infection control, including adherence to policies, reporting hazards, and maintaining hygiene.
- Look for explanation of the risk assessment process: identifying hazards, evaluating risks, implementing controls, and reviewing.
- Evidence should demonstrate correct selection, use, and disposal of PPE in accordance with standard precautions.
- Credit should be given for explaining key personal hygiene practices (handwashing, covering cuts, appropriate use of uniforms) and their role in infection prevention.
Assessment Guidance
Guidance for achieving higher grades
- 💡When describing roles and responsibilities, always refer to workplace policies and national guidelines (e.g., Northern Ireland regional policies).
- 💡In risk assessment tasks, use a structured approach like the Health and Safety Executive’s five-step model to show systematic thinking.
- 💡For PPE demonstrations, articulate the donning and doffing sequence clearly and explain the rationale for each step.
- 💡Relate personal hygiene practices to specific scenarios (e.g., managing a wound, preparing food) to demonstrate application.
- 💡Use case studies to illustrate how poor infection control can lead to outbreaks, linking cause and effect.
- 💡Use specific examples from care settings to illustrate your answers, such as how you would communicate with a service user who has hearing loss or dementia. This shows application of theory to practice.
- 💡Link your answers to Northern Ireland legislation and policies, like the Health and Social Care (Reform) Act (Northern Ireland) 2009 or the NISCC Codes of Practice. Examiners look for local context.
- 💡When discussing person-centred care, always mention involving the individual, their family, and other professionals in care planning. Use the acronym 'PIES' (Physical, Intellectual, Emotional, Social) to structure holistic needs.
Common Mistakes
Common errors to avoid in your coursework
- Confusing colonisation with infection: failing to distinguish that not all microorganisms cause harm.
- Assuming all infections are contagious; many infections are opportunistic or endogenous.
- Overlooking the importance of environmental cleaning, focusing only on direct patient contact.
- Neglecting to mention that PPE must be changed between tasks and patients to prevent cross-contamination.
- Believing that handwashing alone is sufficient without recognising the 5 moments of hand hygiene or using alcohol gel incorrectly.
- Misconception: Person-centred care means always doing what the person wants. Correction: It involves balancing their wishes with professional judgment and safety considerations, such as when a person lacks capacity under the Mental Capacity Act.
- Misconception: Safeguarding only applies to children. Correction: Safeguarding covers all vulnerable groups, including adults at risk, and requires reporting concerns to the appropriate authorities like the PSNI or NISCC.
- Misconception: Duty of care means you must prevent all risks. Correction: You must manage risks proportionately, supporting individuals to make informed choices even if they involve some risk, as long as it is not serious harm.
