Richard Skolnik, lecturer for Yale's Essentials of Global Health course on Coursera, covers unintentional injuries as a major global health burden. He walks through the scope of the problem, including road traffic accidents, falls, drowning, burns, and poisoning, and breaks down who is most affected by age, income level, and region. The lecture follows the course's standard format, examining the nature and burden of the condition, its determinants and risk factors, and the cost-effective interventions available to reduce injury deaths and disability, such as road safety regulation, helmet and seatbelt laws, and improved emergency care systems. As with other sessions in the series, the emphasis falls on low and middle income countries, where injury rates and access to trauma care diverge sharply from wealthier nations.
