New Year's Eve injuries caused by celebratory gunfire--Puerto Rico, 2003.

Bullets fired into the air during celebrations fall with sufficient force to cause injury and death. However, few data exist regarding the epidemiology of injuries related to celebratory gunfire. In Puerto Rico, where such celebratory actions are common, news media reports have indicated that approximately two persons die and an estimated 25 more are injured each year from celebratory gunfire on New Year's Eve. The Puerto Rico Department of Health (PRDOH) invited CDC and local law enforcement agencies to assist in the investigation of injuries resulting from celebratory gunfire that occurred during December 31, 2003-January 1, 2004. This report summarizes the findings of that investigation, which determined that 1) bullets from probable celebratory gunfire caused 19 injuries, including one death and 2) such injuries affected a higher percentage of women and children aged <15 years than injuries from noncelebratory gunfire, with the majority occurring in certain public housing areas in densely populated, metropolitan San Juan. Education and enforcement of existing laws are needed to prevent these injuries.
