Spain's El País newspaper published a series of infographics and COVID-19 FAQ that exhaustively answers all questions about the virus.
This is by far the most information in one resource that I've found. Most importantly, it contains answers to all the practical questions we have about COVID-19. How do I get tested? What do I do if I live with someone who tested positive? It includes a flow chart explaining what to do if you feel sick, so that there are zero doubts or confusion about how to respond to feeling ill. One of the best graphics, that contributed to my own behavior change, shows the number of people that can be infected in vehicles we most often use--a car, a bus, a plane--so the next time that you find yourself in one of those spaces, you think about your proximity to others and the possibility of contracting the virus, and, moreover, the risk that travel brings to yourself and of spreading to others.
In what ways did you change your behaviors as a result of this resource?
I avoided public transportation as much as possible.
In what ways did you share this information?
WhatsApp and email to Spanish-speaking friends and coworkers
What information do you feel you are missing about COVID-19?
In the US there is no clear guidance on what to do if you think you have COVID-19 or if you were in close contact with someone who has tested positive. I know from research that in my state I need to call the state health department, but beyond that there is no road map for what would happen to me next.
