Hygi\u00e8ne des mains (du grec hygieinos<\/em> \u2014 sain) \u2014 il s’agit d’un ensemble de mesures pr\u00e9ventives visant \u00e0 l’\u00e9limination m\u00e9canique ou la destruction chimique des micro-organismes pr\u00e9sents sur la peau des mains.<\/p>\n\n

Dans la m\u00e9decine moderne, cela est reconnu comme la m\u00e9thode la plus simple, efficace et \u00e9conomiquement justifi\u00e9e pour interrompre la transmission des maladies infectieuses.<\/p>\n\n

\u00c9tiologie et physiopathologie<\/strong><\/h2>\n\n

La flore microbienne de la peau des mains humaines se divise en deux types :<\/p>\n\n

    \n
  • flore r\u00e9sidente (permanente)<\/strong> \u2014 elle vit dans les couches profondes de l’\u00e9piderme et ne cause g\u00e9n\u00e9ralement pas de maladies ;<\/li>\n\n\n\n
  • flore transitoire (temporaire)<\/strong> \u2014 elle est principalement constitu\u00e9e de bact\u00e9ries et de virus qui se retrouvent sur les mains par contact avec des surfaces contamin\u00e9es ou des fluides biologiques de patients infect\u00e9s (c’est elle qui est \u00e0 l’origine de la plupart des infections).<\/li>\n<\/ul>\n\n

    Le lavage des mains au savon provoque l’\u00e9mulsification de la couche lipidique de la peau dans laquelle les microbes sont emprisonn\u00e9s, apr\u00e8s quoi ils sont \u00e9limin\u00e9s \u00e0 l’eau. Les antiseptiques cutan\u00e9s \u00e0 base d’alcool agissent diff\u00e9remment : ils provoquent une d\u00e9naturation imm\u00e9diate (coagulation) des prot\u00e9ines et la destruction des enveloppes lipidiques des particules virales et bact\u00e9riennes.<\/p>\n\n

    Pour une \u00e9limination compl\u00e8te des agents pathog\u00e8nes, l’exposition (temps pendant lequel le produit doit rester sur la peau) doit \u00eatre strictement respect\u00e9e :<\/p>\n\n

      \n
    • antiseptique<\/strong> \u2014 jusqu’\u00e0 un s\u00e9chage naturel complet ;<\/li>\n\n\n\n
    • lavage des mains au savon<\/strong> \u2014 pas moins de 15 \u00e0 20 secondes.<\/li>\n<\/ul>\n\n

      Importance clinique<\/strong><\/h2>\n\n

      En milieu hospitalier, l’hygi\u00e8ne des mains est fondamentale pour le contr\u00f4le des infections. Elle pr\u00e9vient le d\u00e9veloppement d’infections nosocomiales (hospitali\u00e8res) qui sont souvent caus\u00e9es par des bact\u00e9ries multir\u00e9sistantes.<\/p>\n\n

      Dans la vie quotidienne, l’hygi\u00e8ne des mains est cruciale pour pr\u00e9venir les infections respiratoires et intestinales. \u00c9tant donn\u00e9 que de nombreux virus (norovirus, rotavirus) peuvent rester viables longtemps sur diverses surfaces (comme les poign\u00e9es de porte), un traitement r\u00e9gulier des mains rompt le mode de transmission par contact, r\u00e9duisant ainsi le risque de maladie.<\/p>\n","protected":false},"excerpt":{"rendered":"
