Harnessing the Power of Mobile and Messaging Apps for Risk Communication and Intervention During the COVID-19 Pandemic: Lessons from the Western Pacific

Summary:The spread of mis- and disinformation on mobile and messaging apps during the COVID-19 pandemic not only fuelled anxieties and mistrust in health authorities but also undermined the effectiveness of the overall public health response. For context, mobile and messaging apps help users stay informed and connected to their families, friends, colleagues, and communities. However, during the COVID-19 pandemic, these apps were also one of the primary channels where misinformation and disinformation circulated.Recognizing the importance of including mobile and messaging apps in risk communication and emergency response strategies, the World Health Organization (WHO) and some countries in the WHO Western Pacific Region independently piloted initiatives to reach messaging app users, meet their evolving information needs, and streamline health ministry communication.The enhanced use of mobile and messaging apps enabled consistent and timely communication, improving coordination during the COVID-19 pandemic. Leveraging their features also helped identify and potentially fill crucial information gaps, mitigating the harms of mis- and disinformation and fostering stronger trust in health authorities.The findings from the work carried out by WHO and countries in the Western Pacific Region identified some promising innovative communication interventions using mobile and messaging apps. While these interventions should be further explored and evaluated, they have demonstrated that interventions need to be proactive, flexible, and able to adapt to changes in misinformation and disinformation content shared through messaging apps.
