[h=1]Communicating infectious disease prevalence through graphics: Results from an international survey.[/h] Fagerlin A[SUP]1[/SUP], Valley TS[SUP]2[/SUP], Scherer AM[SUP]3[/SUP], Knaus M[SUP]4[/SUP], Das E[SUP]5[/SUP], Zikmund-Fisher BJ[SUP]6[/SUP].

[h=3]Abstract[/h] [h=4]BACKGROUND:[/h] Graphics are increasingly used to represent the spread of infectious diseases (e.g., influenza, Zika, Ebola); however, the impact of using graphics to adequately inform the general population is unknown.
[h=4]OBJECTIVE:[/h] To examine whether three ways of visually presenting data (heat map, dot map, or picto-trendline)-all depicting the same information regarding the spread of a hypothetical outbreak of influenza-influence intent to vaccinate, risk perception, and knowledge.
[h=4]DESIGN:[/h] Survey with participants randomized to receive a simulated news article accompanied by one of the three graphics that communicated prevalence of influenza and number of influenza-related deaths.
[h=4]SETTING:[/h] International online survey.
[h=4]PARTICIPANTS:[/h] 16,510 adults living in 11 countries selected using stratified random sampling based on age and gender.
[h=4]MEASUREMENTS:[/h] After reading the article and viewing the presented graphic, participants completed a survey that measured interest in vaccination, perceived risk of contracting disease, knowledge gained, interest in additional information about the disease, and perception of the graphic.
[h=4]RESULTS:[/h] Heat maps and picto-trendlines were evaluated more positively than dot maps. Heat maps were more effective than picto-trendlines and no different from dot maps at increasing interest in vaccination, perceived risk of contracting disease, and interest in additional information about the disease. Heat maps and picto-trendlines were more successful at conveying knowledge than dot maps. Overall, heat maps were the only graphic to be superior in every outcome.
[h=4]LIMITATIONS:[/h] Results are based on a hypothetical scenario.
[h=4]CONCLUSION:[/h] Heat maps are a viable option to promote interest in and concern about infectious diseases.
