The Australian measles control campaign was launched in 1998. In the six months after the campaign, coverage of measles, mumps and rubella (MMR) vaccine improved greatly and measles seropositivity rose from 82% to 89% in preschool children and to 94% in 6-11 year olds. Uptake fell again a year later (Bulletin of the World Health Organization 2001;79:882-7). Minerva thinks this indicates the need for annual campaigns, but she wonders if Australia—like the United Kingdom—also fell victim to negative media coverage.
It's official. Sexual activity increases the risk of myocardial infarction (relative risk 2.1 during the hour after sexual activity, with a risk of 4.4% in sedentary patients). But the absolute risk per hour is extremely low, and only 1.3% of 699 patients admitted with a first heart attack had participated in sex up to two hours before the infarct. The authors urge that patient counselling should focus on improved fitness, not abstention from sex (Heart 2001;86:387-90).
