Banning displays of cigarettes in shops could help to reduce smoking amongst teenagers. Teens interviewed before and after a 2009 ban on such displays in Ireland were less likely to recall advertising displays, and said fewer of their friends smoked, after the ban (Tobacco Control, DOI: 10.1136/ tc.2010.038141). Over the past decade, the number of new HIV infections worldwide has decreased by 20 per cent reports the United Nation's AIDS partnership. The rate of new infections has decreased by more than 25 per cent in 33 of the 63 countries from which they had reliable data, with the success attributed to prevention measures.
