What is poor sanitation according to WHO?

According to the World Health Organization (WHO), poor sanitation refers to inadequate facilities and practices that do not ensure safe disposal of human waste, leading to contamination of the environment and increased health risks. This includes lack of access to clean toilets, unsafe disposal of wastewater, and insufficient hygiene practices. Poor sanitation can contribute to the spread of diseases, particularly in vulnerable populations, and is a significant barrier to achieving health equity and sustainable development.
