An outbreak of Norwalk-like viral gastroenteritis in holidaymakers travelling to Andorra, January–February 2002

Abstract
A retrospective cohort study was conducted to investigate an outbreak of Norwalk-like viral gastroenteritidis that occurred in Irish holidaymakers visiting Andorra, in January–February 2002. Preliminary results showed the risk exposure was higher for tourists who stayed in Soldeu and consumed ice cubes in their drinks (OR = 2.5, 95% CI [1.3–4.6)], after logistic regression and adjusting for sex and water consumption).
