Preventing childhood injuries would seem a tough task. But there’s a long list of proper ways to make the world safer for children. The World Health Organization wants its 193 member nations — and especially those in the developing world, where most deaths from injury occur — to know that accidents don’t have to happen.
    Many prevention strategies applied by rich societies are only now being adopted in the developing world. They include strict drunken-driving laws; requirements that wells be covered; installing window guards in upper-story apartments; and establishing poison-control centers and burn units.
    Traffic injuries are perhaps the most dramatic example of how much could be gained if prevention measures could be carried out more broadly. Traffic injuries are the leading cause of death worldwide for 15- to 19-year-olds and the second-leading cause for children 5 to 14. But the use of seat belts, child seats and helmets is still not required in many countries.
    For society, the payoff of prevention efforts is huge. For every $1 invested in bike helmets and child seats, for example, $29 is saved in health care, disability and lost income costs. But for individuals, prevention is often economically burdensome. Parents have to work longer and harder if they want to improve their children’s safety condition.
    At the same time, some countries have risks not widely shared by others. Death rates from burns are 11 times as high in developing countries as in industrialized ones. European and American boys and girls have virtually equal rates of death from fire. In South Asia and Southeast Asia, however, girls’ mortality is three times that of boys because girls assist in family cooking at an early age.
