Causes and spread of infection
This subtopic explores the biological agents (bacteria, viruses, fungi, parasites) that cause infections, with emphasis on those relevant to maternity settings such as Group B Streptococcus and MRSA. It also examines transmission routes—contact, droplet, airborne—and the role of healthcare workers in breaking the chain of infection. Understanding these principles is critical for protecting vulnerable mothers and newborns from healthcare-associated infections.
Assessment criteria
Topic Overview
The ABBE Level 3 Diploma in Healthcare Support (Maternity) is a specialised qualification designed for healthcare assistants and support workers who wish to work in maternity services. It covers the essential knowledge and skills required to provide safe, compassionate, and effective support to women, their partners, and families during pregnancy, labour, birth, and the postnatal period. This diploma is part of the wider Health and Social Care framework and aligns with the NHS Career Framework, enabling learners to progress into roles such as Maternity Support Worker or Assistant Practitioner.
The curriculum is structured around core units that include communication, health and safety, person-centred care, and specific maternity topics such as antenatal and postnatal care, infant feeding, and recognising signs of complications. Learners develop practical competencies in monitoring vital signs, assisting with breastfeeding, and providing emotional support. Understanding this qualification is crucial for anyone aiming to deliver high-quality maternity care within a multidisciplinary team, as it bridges the gap between basic healthcare assistance and more advanced clinical responsibilities.
This diploma not only equips students with technical knowledge but also emphasises the importance of empathy, cultural sensitivity, and evidence-based practice. It prepares learners to work in a variety of settings, including hospitals, community clinics, and birth centres. By mastering this content, students contribute to positive maternal and neonatal outcomes, making a tangible difference in the lives of families during a transformative life event.
Key Concepts
Core ideas you must understand for this topic
- →Person-centred care: Tailoring support to the individual needs, preferences, and values of the woman and her family, ensuring dignity and respect throughout the maternity journey.
- →Antenatal and postnatal care: Understanding the physiological and emotional changes during pregnancy and after birth, including monitoring maternal and fetal wellbeing, recognising warning signs, and providing appropriate support.
- →Infant feeding: Knowledge of breastfeeding techniques, benefits, and common challenges, as well as safe formula preparation and feeding practices, to support informed choices.
- →Infection prevention and control: Strict adherence to hand hygiene, use of personal protective equipment, and safe disposal of clinical waste to protect mothers, babies, and staff from healthcare-associated infections.
- →Safeguarding: Recognising signs of abuse or neglect in vulnerable women and newborns, and following local policies to report concerns appropriately.
Learning Objectives

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for correctly classifying common maternity-related pathogens by type (e.g., bacteria, virus) and providing relevant examples.
- Award credit for accurately describing the chain of infection and identifying at least three points where intervention can prevent transmission.
- Award credit for explaining the difference between colonization and infection, particularly in relation to Group B Streptococcus in pregnancy.
- Award credit for demonstrating understanding of standard infection control precautions relevant to maternity care, such as hand hygiene, PPE, and safe handling of sharps.
Assessment Guidance
Guidance for achieving higher grades
- 💡When answering written tasks, always link infection control measures to specific pathogens and modes of transmission, showing tailored reasoning.
- 💡In practical assessments, demonstrate thorough hand hygiene technique and explain the rationale for each step, referencing the '5 moments' for hand hygiene in healthcare.
- 💡Use case studies from maternity settings to illustrate how infections can spread and be prevented, as this shows application of knowledge.
- 💡Ensure you can list common infections that pose risks to neonates, such as Group B Streptococcus, E. coli, and Herpes simplex, and describe their transmission routes.
- 💡Use real-life examples from your placement or case studies to illustrate your answers. Examiners reward application of theory to practice, especially when you explain how you adapted care to meet individual needs.
- 💡Memorise key guidelines and policies, such as the NHS Long Term Plan for maternity care or NICE guidelines on antenatal care. Referencing these shows depth of knowledge and a commitment to evidence-based practice.
- 💡In written assessments, structure your answers clearly: define the concept, explain its importance, give an example, and link to the role of a maternity support worker. This logical flow helps you hit all marking criteria.
Common Mistakes
Common errors to avoid in your coursework
- Confusing colonization with active infection; failing to recognize that a mother with Group B Streptococcus may be asymptomatic but still require intrapartum antibiotics.
- Assuming that all infections are caused by bacteria, overlooking viruses like Hepatitis B or HIV that can be transmitted perinatally.
- Misunderstanding the difference between droplet and airborne transmission, leading to incorrect selection of PPE.
- Neglecting the role of contaminated surfaces (fomites) in transmission within the maternity ward.
- Misconception: Maternity support workers only assist with basic tasks like cleaning and fetching supplies. Correction: They play a vital role in clinical care, such as monitoring vital signs, assisting with breastfeeding, and providing emotional support under the supervision of midwives.
- Misconception: All women have the same pregnancy and birth experience. Correction: Each woman's journey is unique; support must be tailored to cultural, medical, and personal circumstances, including high-risk pregnancies or previous traumatic births.
- Misconception: Infant feeding is instinctive and requires no support. Correction: Many mothers face challenges with breastfeeding; support workers must be trained to offer practical help and signpost to specialist services like lactation consultants.
