MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 29576516
Resumo: To mark the centenary of the 1918 influenza pandemic, the broadcasting network BBC have put together a 75-min documentary called 'Contagion! The BBC Four Pandemic'. Central to the documentary is a nationwide citizen science experiment, during which volunteers in the United Kingdom could download and use a custom mobile phone app called BBC Pandemic, and contribute their movement and contact data for a day. As the 'maths team', we were asked to use the data from the app to build and run a mo (mais)

Much ado about flu: A mixed methods study of parental perceptions, trust and information seeking in a pandemic.
