“…7 This paper complements an earlier PHRP paper by McCaffery and colleagues, emphasising the importance of highly targeted COVID-19 communications in diverse contexts to address the large differences in knowledge, attitudes and behavioural intentions among different culturally and linguistically diverse populations. 8 Other papers in this edition explore additional themes in public communication, including the paper by Bzozek and Karipidis highlighting the importance of direct community engagement in the communication of issues that invoke community concerns, such as exposure to electromagnetic radiation 9 , and the work of Pettigrew and colleagues on developing and testing messages to motivate older people to be more active 10 . Complementing these is the paper by Georgiou et al on the delivery of safe and effective test result communication, management and follow-up.…”
