Introduction and Sig.ificance. 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.

Purpose.and Obje.tive.: To appraise.the.community that acknowle.g.0} burns, first aid, and associate. factors among.the.community population in Jazan City, Saudi Arabia. The.pape. aims to ide.tify limitations to e.courag.0}additional re.e.rch and pe.suade.le.islators to de.e.op improve. burn-injury care.re.omme.dations and training.prog.ams. Mate.ials and Me.hods: An obse.vational-base. sample.surve. was conducte. among.the.pe.ple.who live.in Jazan City ag.ng.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. prog.am, 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.tag.0}. Also, the.Chi-square.te.t was use. to inve.tig.te.the.re.ation be.we.n diffe.e.t variable., with a sig.ificance.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..
