Abstract
An investigation is undertaken to analyze the human lightning fatalities in Swaziland. A total of 123 victims of lightning-related death were identified from the records of the Royal Swaziland Police Service and the local printed media for the period 2000–2007. An annual average fatality rate of 15.5 people per million, the highest recorded rate in the world, was obtained. The results also reveal that 66% were male, most (67%) of them were within the 10–39 age group with an average age of 28 years. Lightning fatalities occurred from September to May mainly in the afternoon (1400–1800 h). Deaths most commonly occurred indoors inside rural houses (17%), whilst walking (16%) and under a tree (14%). The incidents resulted in multiple fatalities in 22% of the cases with an average of 1.4 casualties per incident. The need for awareness campaigns, protection measures and detailed investigation is highlighted.
