Achieving universal access to WASH in health care facilities requires political will and strong leadership at both national and facility levels, but is highly cost-effective, and would yield substantial health benefits. A global analysis estimated that universal basic WASH services in health care facilities could be achieved in 46 least developed countries (LDCs) by 2030 for less than US$10 billion, which represents additional expenditures of less than US$1 per person per year.
