Abstract Human behaviour is known to be crucial in the propagation of infectious diseases through respiratory or close-contact routes like the current SARS-CoV-2 virus. Intervention measures implemented to curb the spread of the virus mainly aim at limiting the number of close contacts, until vaccine roll-out is complete. Our main objective was to assess the relationships between SARS-CoV-2 perceptions and social contact behaviour in Belgium. Understanding these relationships is crucial to maximize interventions' effectiveness, e.g. by tailoring public health communication campaigns. In this study, we surveyed a representative sample of adults in Belgium in two longitudinal surveys (8 waves of survey 1 in April 2020 to August 2020, and 11 waves of survey 2 in November 2020 to April 2021). Generalized linear mixed effects models were used to analyse the two surveys. Participants with low and neutral perceptions on perceived severity made a significantly higher number of social contacts as compared to participants with high levels of perceived severity after controlling for other variables. Furthermore, participants with higher levels of perceived effectiveness of measures and perceived adherence to measures made fewer contacts. However, the differences were small. Our results highlight the key role of perceived severity on social contact behaviour during a pandemic. Nevertheless, additional research is required to investigate the impact of public health communication on severity of COVID-19 in terms of changes in social contact behaviour.

The commentary focuses on the spread of Covid-19 misinformation in Italy, highlighting the dynamics that have impacted on its pandemic communication. Italy has recently been affected by a progressive erosion of trust in public institutions and a general state of information crisis regarding matters of health and science. In this context, the politicization of health issues and a growing use of social media to confront the Coronavirus “infodemic” have led the Italian Ministry of Health to play a strategic role in using its official Facebook page to mitigate the spread of misinformation and to offer updates to online publics. Despite this prompt intervention, which increased the visibility and reliability of public health communication, coordinated efforts involving different institutions, media and digital platform companies still seem necessary to reduce the impact of misinformation, as using a multichannel strategy helps avoid increasing social and technological disparities at a time of crisis.

The Impact

In times of crisis, a government’s communication with the public is fundamental, as one of the government’s main tasks is to provide critical information to protect the population. In the current context of the COVID-19 pandemic, public health communication has been paramount because of the elevated risk of contagion. Moreover, in public health communication, experts play a pivotal role by providing reliable information on the basis of their technical expertise. The impact of the COVID-19 pandemic is often compared to that of the Spanish flu, a pandemic occurring in 1918-1919, whose global spread decimated tens of millions of people. This contribution aims to assess the role of experts in the two crises by highlighting the differences in France’s public health communication during the two events. Assuming that the objectives of public health communication during the two pandemics were more or less identical, i.e. to prevent the spread of disease and inform and protect the public, the paper inquires about the means used to achieve them, focusing on the contribution of experts. The main characteristics of public health communication during the Spanish flu will be investigated by analysing articles published in the period between 1918 and 1919 in two French newspapers Le Matin and Le Petit Parisien. In terms of the current COVID-19 pandemic, this paper will probe articles published since December 2019 in the newspaper Le Monde.

Abstract The realization that not only research but also effective communication is essential to promoting and protecting the health of the public was a fundamental milestone in the emerging discipline of public health communication. Although we are beginning to talk more and more about health communication, it is, in the common view, still too often identified as a soft skill of the individual professional, and therefore as a minor competence in public health. Fortunately, many of today's public health leaders realize that promoting health and protecting the public require effective public health communication - as emerged clearly during EUPHA2019 conference in Marseille. The essential components of the communication process (channel, source, receiver, and message) are dynamic and change continuously in public health: emergencies follow one another rapidly, and communication channels evolve very quickly in the digital era. The impact, trust, and authority of traditional media are in decline. People are also willing to actively participate and share their views and information, including on health issues, through social networks. This explains the emergence of the new social media (blogs, Twitter, Facebook, Instagram, Tik Tok) as a central space for communicating and re-connecting with the public. Websites were mentioned as widely used to convey health messages, like ongoing health campaigns addressed to different groups (e.g. campaign on seasonal influenza vaccination) or during crisis communication (e.g. absolutely up to date is the example of coronavirus disease 2019). This workshop aims to explore the importance of appropriate communication by analysing practical examples of the diversity of communication modalities, language, target audiences and objectives. Furthermore, public health communication, to be effective, requires an integrated approach to engage the relevant stakeholders such as research institutes, health professionals, partner organisations (e.g. private institutions), policymakers, associations (e.g. population representatives, patients' associations, CSOs/NGOs, citizens associations protecting the poor) and individuals. The use of health communication principles is fundamental at all levels, from government organizations and agencies at central and sub-national level to individuals and citizens: public health experts need to advocate policymakers and all stakeholders, who interact with each other determine the health system and its governance and are involved in the decision-making process, to empower the population, that never more than now require to be the principal actor in their own health decision. Key messages Public health communication is an essential component of any effective public health strategy and initiative, yet it is often neglected and under-resourced. Communication in public health is multifaceted: it is required in a diverse range of scenarios; it may target different population groups and engage various institutions and experts.

This paper provides a psychological perspective on the possible effect of the Internet on the decision against vaccination. The reported importance of the Internet in health decisions is still low, but rising; especially the amount of interactive use of the Internet is increasing, e.g. due to the use of social media. It is argued that the fact that individuals do not report the Internet to be an important source of information does not necessarily mean that the information obtained in their Internet searches is not influential in their decisions. Evidence is summarised here regarding the (anti-)vaccination information on the Internet, and its influence on risk perceptions and on vaccination intentions and behaviour in relation to the encoded information. The conclusion suggests that scholars should strive to explain the underlying processes and potential mediators of vaccination decisions to increase the effectiveness of health communication. In reference to a definition of evidence-based medicine, a great future challenge lies in evidence-based public health communication based on interdisciplinary research involving public health, medical research, communication science and psychology.

Abstract One of the largest nationwide bursts of the first COVID-19 outbreak occurred in Spain, where infection expanded in densely populated areas through March 2020. We analyse the cumulative growth curves of reported cases and deaths in all Spain and two highly populated regions, Madrid and Catalonia, identifying changes and sudden shifts in their exponential growth rate through segmented Poisson regressions. We associate these breakpoints with a timeline of key events and containment measures, and data on policy stringency and citizen mobility. Results were largely consistent for infections and deaths in all territories, showing four major shifts involving 19–71% reductions in growth rates originating from infections before 3 March and on 5–8, 10–12 and 14–18 March, but no identifiable effect of the strengthened lockdown of 29–30 March. Changes in stringency and mobility were only associated to the latter two shifts, evidencing an early deceleration in COVID-19 spread associated to personal hygiene and social distancing recommendations, followed by a stronger decrease when lockdown was enforced, leading to the contention of the outbreak by mid-April. This highlights the importance of combining public health communication strategies and hard confinement measures to contain epidemics.

Abstract Background Following the outbreak of the COVID-19 pandemic, a change in the incidence and transmission of respiratory pathogens was observed. Here, we retrospectively analyzed the impact of COVID-19 on the epidemiologic characteristics of Mycoplasma pneumoniae infection among children in Chengdu, one of the largest cities of western China. Method M. pneumoniae infection was diagnosed in 33,345 pediatric patients with respiratory symptoms at the Chengdu Women’s & Children’s Central Hospital between January 2017 and December 2020, based on a serum antibody titer of ≥1:160 measured by the passive agglutination assay. Differences in infection rates were examined by sex, age, and temporal distribution. Results Two epidemic outbreaks occurred between October-December 2017 and April-December 2019, and two infection peaks were detected in the second and fourth quarters of 2017, 2018, and 2019. Due to the public health response to COVID-19, the number of positive M. pneumoniae cases significantly decreased in the second quarter of 2020. The number of M. pneumoniae infection among children aged 3–6 years was higher than that in other age groups. Conclusions Preschool children are more susceptible to M. pneumoniae infection and close contact appears to be the predominant factor favoring pathogen transmission. The public health response to COVID-19 can effectively control the transmission of M. pneumoniae.

Abstract Many countries apply fiscal policies to promote healthy diets to reduce the risk factors of NCDs. In 2011, a public health product tax (PHPT) was introduced in Hungary, taxing non-staple food products that carry proven health risks when consumed. The objectives of PHPT were to promote healthier eating habits by increasing the availability of healthy choices; to encourage reformulation; and to increase revenues for public health. With the purpose of evaluating the social and economic effects of PHPT, impact assessments (IAs) were conducted in 2012, 2014, and in 2018. The IA in 2018 was conducted within the framework of an EU-cofunded development project. To measure the awareness of the population on the law; to assess the population's attitude towards PHPT; to map the consumption patterns and to examine the major factors influencing food choices were fundamental parts of the IAs. We aim to present the findings of the latest IA and compare them to the results of the previous studies. Population surveys with questionnaires including the same questions were applied in the three assessments, hence changes during the 6 years could be detected. A sample of the adult population was involved in form of personal interviews in each IA. Based on the results, the awareness of PHPT was less (66%) in 2018 than in 2012 (72%). The adult population's consumption of the taxed products increased in all categories between 2012 and 2018 (except for salty condiments). Sociodemographic factors and awareness of the law correlated with the consumption of certain PHPT products. Taste was the primary determinant of food choice both in 2012 and 2018. The role of the price and the energy content in food choices were decreased significantly by 2018. A higher proportion of people identified the aims of PHPT correctly and agreed with them in 2018. The results draw attention to the importance of further interventions and the need of targeted health communication. Key messages The impact of the PHPT should continue to be monitored and evaluated. To achieve the aims of PHPT in the long term, it is needed to use more effective health communication, furthermore harmonized intersectoral actions should be also implied to promote healthy diet.
