INFECTION
Germ Defence content was rapidly adapted throughout the pandemic using state-of-the-art evidence, theory and the person-based approach [The original Germ Defence intervention drew on the theory of planned behaviour [The single-session intervention sought to improve users’ awareness of risks of infection and transmission, increase skills and confidence to reduce risks and use behaviour change techniques (such as making if–then plans) to support behaviours. The Germ Defence content was tailored such that a user selected one of four streams that was relevant to the user’s situation:To protect themselves generallyTo protect others if the user was showing symptomsTo protect themselves if household member(s) showed symptomsTo protect a household member who is at high riskClear and detailed advice was provided for self-isolating, social distancing, cleaning, wearing face coverings, ventilation and handwashing.
