Although this came up on the ProMed mailing list today, evidence of the flu associated rash was recorded from an outbreak in March of 2014 in British Columbia, Canada. The study, published in Influenza and Other Respiratory Viruses, found 2 elementary students and 2 high school students presenting with a maculopapular pruritic rash and Influenza like illness.

Although this is an abnormal association in influenza infection, it is not completely novel. The researchers report two previous case associations with exanthem and influenza occurring in one 11 year old from India, and 4 German school children. However, this is the first time that Influenza has been associated with exanthem in North America.
Thanks ProMed for bringing weird viral clinical presentations to my email inbox! Happy finals week fellow virologists.
