En el presente informe se señalan las principales deficiencias que padecen los servicios WASH nivel mundial: un tercio de los establecimientos de salud no disponen de los elementos necesarios para limpiarse las manos en los lugares donde se presta atención; uno de cada cuatro establecimientos care...ce de servicios básicos de agua, y uno de cada diez no cuenta con servicios de saneamiento. Esto significa que 1800 millones de personas son usuarias de unos establecimientos que carecen de servicios básicos de agua, y que 800 millones de personas acuden a centros que no disponen de aseos. Este problema es aún mayor en los 47 países menos adelantados del mundo, donde la mitad de los establecimientos de salud carecen de servicios básicos de agua.
