Infection control is one of the most practical, exam-heavy, and clinically urgent topics in Community Health Nursing. For every GNM, B.Sc Nursing and Post Basic student, mastering infection prevention is not just a theory paper requirement — it is a daily responsibility on the ward, in the OT, during home visits and in community outreach programmes.
Why Infection Control Matters in Nursing
According to the World Health Organization (WHO), 7 out of every 100 patients in acute-care hospitals in developed countries, and 10 out of 100 in developing countries, acquire at least one healthcare-associated infection (HAI) during their stay. In India, surveillance data from ICMR AMR Hub consistently shows ventilator-associated pneumonia, catheter-associated urinary tract infections and surgical site infections as the top three HAIs. Nurses are the first line of defence — because hand hygiene, aseptic technique, correct PPE use and biomedical waste segregation are nursing-led activities on every shift.
What You Will Learn in This Guide
This 15-chapter unit walks you through every concept that commonly appears in both internal and university exams. Starting with the nature of infection, you’ll move through the classic chain of infection (agent → reservoir → portal of exit → mode of transmission → portal of entry → susceptible host), the stages of infection, host-defence mechanisms, and the differences between medical and surgical asepsis. You’ll also study the WHO 5 Moments of Hand Hygiene, correct donning and doffing of PPE, and the Bio-Medical Waste Management Rules 2016 (amended 2019) that are directly tested in Karnataka, All-India, NORCET and State-level nursing exams.
How to Use This Index
The table below is the complete unit roadmap. Follow it in order on a first read; from then on, use it as a quick revision checklist. Each linked topic opens into a detailed PDF-grade note with diagrams, exam-weighted MCQs and viva questions. Clinical students are strongly advised to pair this unit with the hands-on infection-control practical record and checklist available in our Study Materials shop.

High-Yield Exam Tips for Infection Control
- Draw the chain of infection — it appears in almost every short-answer paper.
- Memorise WHO’s 5 Moments and 7-step hand-washing sequence (duration: 40–60 seconds).
- Learn colour-coded waste bags: yellow, red, white (translucent puncture-proof), blue — a frequent MCQ topic.
- Distinguish standard precautions vs transmission-based precautions (contact, droplet, airborne).
- Keep ready one-line definitions for nosocomial infection, iatrogenic infection, opportunistic infection and endogenous infection.
