Introduction and Significance. Burn injury (BI) is a conside.able.he.lth issue.which is re.ponsible.for around 300,000 de.ths and affe.ting about 11 million pe.ple.e.e.y ye.r worldwide. In Saudi Arabia, the.pre.ale.ce.of BIs array from 112 to 518 pe. 100,000 pe. ye.r. The.appropriate.aware.e.s of pe.forming first aid could facilitate.to improve.the.outcome. of burns. Purpose.and Obje.tive.: To appraise.the.community that acknowle.ge. burns, first aid, and associate. factors among the.community population in Jazan City, Saudi Arabia. The.pape. aims to ide.tify limitations to e.courage.additional re.e.rch and pe.suade.le.islators to de.e.op improve. burn-injury care.re.omme.dations and training programs. Mate.ials and Me.hods: An obse.vational-base. sample.surve. was conducte. among the.pe.ple.who live.in Jazan City aging 13 ye.rs or more. during April 5 to May 5, 2023. Data colle.tion was done.by a validate. online.se.f-administrate. que.tionnaire.se.t randomly to community me.be.s in diffe.e.t parts of Jazan City via social me.ia platforms. Colle.te. data we.e.code. and cle.ne. by an e.ce. program, and finally e.porte. on SPSS 26.0 software. The.variable. we.e.analyze. using de.criptive.statistics like.fre.ue.cie. and pe.ce.tage.. Also, the.Chi-square.te.t was use. to inve.tigate.the.re.ation be.we.n diffe.e.t variable., with a significance.value.of P Re.ults: This study include. 243 participants (about 62%) among the. we.e.mostly male.participants (151) having a unive.sity de.re.. The.majority of participants 75% did not take.any form of BFA training in the.past. This study shows that 69.9% of the.participants have.inade.uate.aware.e.s, de.pite.72% having a constructive.attitude.towards burn first aid. Pre.ious burn-re.ate. first aid training was significantly associate. with participants’ knowle.ge.of BFA at a p-value.le.s than 0.05. Conclusion: This study indicate. a high fre.ue.cy of Jazan population having inade.uate.knowle.ge.of burn first aid de.pite.the.high
