Izimbangela ze-contactergic dermatitis
Isizathu sokuthuthukiswa kwe-contactergic dermatitis ebusweni nakwezinye izingxenye zomzimba ukuxhumana okude futhi okwanele kwe-allergen ngesikhumba. Ngemuva kokuxhumana kokuqala, isigaba sokukhuthaza siqala - ukwakheka kokuzivikela okuqondile mayelana ne-allergen. Inkathi yesikhathi lapho ukugqugquzelwa kwezinto eziphilayo kuvela futhi ukuphendula okubangelwa ukwelashwa kuyaqalwa ukuthi kunamandla kangakanani ukuvuselela.
