Background: Armed conflicts can negatively affect health services and cause injuries and death. The recent Arab uprising has been associated with considerable damage to infrastructure and loss of human lives. The aim of this study was to determine mortality, injuries and population displacement that occurred during the recent Libyan armed conflict. Methods: A systematic cross-sectional field survey and non-structured search was carried out over fourteen provinces in six Libyan regions, representing the primary sites of the armed conflict between February 2011 and February 2012. Thirty-five percent of the total area of Libya and 62.4% of the Libyan population were involved in the study. The mortality and injury rates were determined and the number of displaced people was calculated during the conflict period. Results: A total of 21,490 (0.5%) persons were killed, 19,700 (0.47%) injured and 435,000 (10.33%) displaced. The overall mortality rate was found to be 5.1 per 1000 per year (95% CI 4.1-7.4) and injury rate was found to be 4.7 per 1000 per year (95% CI 3.9-7.2) but varied by both region and time, reaching peak rates by JulyAugust 2011. Conclusion: The Libyan armed conflict resulted in great human loss and social damage mirrored by high rates of mortality, injury and human displacement. Such parameters peaked as the conflict escalated and differed according to the Libyan regions and provinces involved. National and international efforts should be combined to overcome the consequences of these conflicts. Pre´sentation: Les conflits arme´s peuvent affecter ne´gativement la sante´et provoquer des blessures et des de´ce`s. Le re´cent soule`vement arabe a e´te´associe´a`des dommages conside´rables aux infrastructures et a`la perte de vies humaines. L'objectif de cette e´tude e´tait de de´terminer le taux de mortalite´, de blessures et les de´placements de population pendant le re´cent conflit arme´en Libye. Me´thodes: Une e´tude de terrain transversale et syste´matique et une recherche non structure´e ont e´te´re´alise´es afin de couvrir six re´gions libyennes incluant 14 provinces, qui e´taient les principaux the´aˆtres du conflit arme´entre fe´vrier 2011 et fe´vrier 2012. Cette e´tude concernait trente-cinq pour cent de la surface totale de la Libye et 62,4 % de la population libyenne. Les taux de mortalite´et de blessures et le nombre de personnes de´place´es ont e´te´calcule´s sur la pe´riode du conflit.Re´sultats: Au total, 21,490 (0,5 %) personnes ont e´te´tue´es, 19,700 (0,47 %) personnes ont e´te´blesse´es et 435,000 (10,33 %) personnes ont e´te´de´place´es. Le taux de mortalite´global a e´te´estime´a`5,1 pour 1 000 par an (IC de 95 % ; 4,1 -7,4) et le taux de blessures global a e´te´estime´a`4,7 pour 1 000 par an (IC de 95 % ; 3,9 -7,2) ; ces taux variaient d'une re´gion a`l'autre. Ils ont varie´pe´riodiquement au cours du conflit et ont atteint un sommet en juillet-aouˆt 2011, la situation s'e´tant aggrave´e pour connaıˆtre ensuite un retour au calme vers la fin du conflit. Conclusion: Le conflit arme´li...
