Human Health and Disease
This subtopic examines the fundamental nature of microorganisms, including bacteria, viruses, and fungi, and their mechanisms in causing infectious diseases. It further explores how personal behaviours such as hygiene practices and vaccination choices directly influence disease transmission. The practical application of this knowledge is crucial for care professionals to implement infection control measures and understand the benefits of medical research in limiting outbreaks.
Assessment criteria
Topic Overview
The Open Awards Level 2 Diploma in Skills for Health and Care Professions (RQF) is a vocational qualification designed to prepare you for a career in health and social care. It covers essential knowledge and skills needed to work in roles such as healthcare assistant, support worker, or care assistant. The diploma includes units on communication, equality and diversity, safeguarding, and person-centred care, all of which are fundamental to providing high-quality care in settings like hospitals, care homes, and community services.
This qualification is important because it gives you a solid foundation in the principles and values of health and social care, such as dignity, respect, and empowerment. You will learn how to support individuals with their daily living activities, understand their rights, and work effectively as part of a team. The diploma also emphasizes the importance of reflective practice and continuous professional development, helping you to grow in your role and improve the care you provide.
Within the wider subject of health and social care, this diploma sits as a Level 2 qualification, which is ideal for those starting their career or looking to formalize their experience. It can lead to further study at Level 3, such as the Access to Higher Education Diploma or apprenticeships in nursing or social work. The skills and knowledge gained are directly applicable to real-world care settings, making it a practical and valuable qualification for anyone passionate about helping others.

Learning Objectives
What you need to know and understand
- Understand the nature of micro-organisms., Understand the effects of personal behviour on the spread of infectious diseases., Understand the impact of medical research and development on the spread of infectious dieases.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a clear understanding of micro-organism classifications and their life cycles, including how they invade hosts and cause disease.
- Look for detailed evidence of how personal behaviours, such as not washing hands or coughing without covering, directly increase transmission risks, and conversely how protective behaviours reduce risk.
- Assess the candidate's ability to critically evaluate the effectiveness of medical research developments, such as the creation of the MMR vaccine, in reducing the prevalence of specific infectious diseases.
Assessment Guidance
Guidance for achieving higher grades
- 💡When describing the nature of micro-organisms, always distinguish between prions, viruses, bacteria, fungi, and protozoa with clear examples of diseases they cause.
- 💡In assignments, contextualise the effects of personal behaviour by referencing specific infection control protocols used in health and care settings, such as the '5 moments for hand hygiene'.
- 💡Discuss the impact of medical research by citing historical and contemporary breakthroughs, such as the development of the smallpox vaccine versus recent mRNA vaccine technology, showing progression.
- 💡Use specific examples from your work experience or case studies to illustrate your answers. For instance, when discussing communication, describe a time you adapted your approach for a person with hearing loss.
- 💡Always link your answers to legislation and policies, such as the Care Act 2014, Health and Safety at Work Act 1974, or the Equality Act 2010. This shows you understand the legal framework.
- 💡In questions about person-centred care, emphasize the individual's rights, choices, and involvement. Avoid generic statements; instead, explain how you would empower the person in a real scenario.
Common Mistakes
Common errors to avoid in your coursework
- Confusing bacteria with viruses and incorrectly assuming antibiotics work on both.
- Assuming that microorganisms are always harmful, ignoring beneficial roles such as gut flora.
- Overlooking the role of asymptomatic carriers in spreading disease.
- Failing to link personal behaviours like not completing a full course of antibiotics to antimicrobial resistance.
- Misconception: Person-centred care means doing whatever the individual wants. Correction: It means involving the individual in decisions and respecting their choices, but within the boundaries of safety, professional guidelines, and legal requirements.
- Misconception: Safeguarding is only about protecting children. Correction: Safeguarding applies to all vulnerable individuals, including adults at risk, and involves preventing abuse and neglect in all care settings.
- Misconception: Equality means treating everyone the same. Correction: Equality is about ensuring everyone has the same opportunities, but it may require different treatment to meet individual needs, such as providing a translator for someone who speaks a different language.
