“Yarraman flu is a virus quickly infecting the US…” The mock announcement was enough to make readers worry. But when the name of the hypothetical illness was changed to “horse flu”, readers reported being less motivated to get a vaccine that would prevent them from contracting the illness. Based on a survey of 16,510 participants from 11 countries, the findings show that the way health information is communicated, matters. The multi-institutional investigation appeared in Emerging Infectious Diseases.
