Health misinformation, a major public health challenge, is increasingly spread through social networking sites such as WhatsApp which is popular among culturally and linguistically diverse (CALD) communities including the African migrant and refugee community, a relatively disadvantaged minority in Australia. Knowledge remains limited about how health misinformation spread occurs through WhatsApp in this community. The present study explored the mechanism of health misinformation circulation on WhatsApp, and the ways members of the African community in Southeast Queensland (SEQ) respond to it. Findings include a technological aspect of WhatsApp, especially technological affordances that facilitate health misinformation spread with features such as sharing and forwarding buttons. Also, at a user or an individual level, trust in significant others favour the reception and sharing of unverified health information to WhatsApp contacts and group members. Although WhatsApp group members, especially leaders usually set up rules to moderate content including health misinformation to primarily preserve harmony in groups, lack of or suboptimal content moderation on WhatsApp exacerbates its spread among community members whose responses vary. Responses include fear and mistrust which could confuse them and hinder acceptance and compliance to public health measures from credible sources such as governments. Therefore, it is essential that public health stakeholders acknowledge and foster information-sharing culture on WhatsApp in the African community. They should also raise awareness among community members and train them on how to deal with health misinformation. The training could focus on reducing negative individual and social influences by improving literacy and self-efficacy in detecting health misinformation and decreasing echo chamber effects. Additionally, the training could emphasise health misinformation management on WhatsApp by leveraging African community leaders’ gatekeeping role and involving them in content moderation.
