The main objective of this project is to improve the Health Risk Communication in pandemic situations of the official public health institutions of the PortugueseGovernment and State. To this end, it is based on the experience of the pandemic COVID-19, where we intend to evaluate and improve the communication anddesign of the different online platforms of these institutions, created to communicate and interact with citizens, namely: DGS; Infarmed; SNS; SPMS; SNS 24; Stayaway Covid; and Estamos On. Currently, information and communication technologies (ICT) are the main means of accessing fast and up-to-date information, namely that related to COVID-19. For this reason, the Portuguese Government and State have made a strong investment in online communication, in order to seek to inform and guide citizens in the most appropriate behaviours and attitudes in the fight against the pandemic.
