An epidemiological assessment during 2007 to 2010 in Rasht, north of Iran on burn patients hospitalized in Velayat Hospital included the total body surface area (TBSA) without reporting LA50 for those patients demonstrating a high prevalence of burn injuries in Iran that requires an increase in knowledge of the society as well as adhering to safety procedures both at home and workplace. In Imam Khomeini Hospital in Kermanashah, Western Iran during 2011-2012; LA50 was reported 50.82% in hospitalized patients. LA50 in burn injuries in Tehran, Iran, among 28690 burn patients from 3 months old to 93 yr old was shown to be 64.7%. 
We aimed to determine the epidemiology and LA50 in burn children in Ghotbedin-Shirazi and Amiralmomenin burn hospitals in Shiraz, southern Iran.
