Approximately 2.1 billion people, or 3 in 10 people worldwide, currently lack access to safe, readily available drinking water at home according to a new report released by the World Health Organization (WHO) and UNICEF in July 2017. The report also states that 4.5 billion people, or 6 in 10 people worldwide, currently lack safely managed sanitation.
Of the 2.1 billion people who have no access to safe drinking water, 844 million do not have even a basic drinking water service. This includes 263 million people who have to spend more than 30 minutes per trip to collect water from sources outside the home, and 159 million who still drink untreated water from surface water sources, such as streams or lakes.
Of the 4.5 billion people who do not have safely managed sanitation, 2.3 billion still do not have basic sanitation services. This includes 600 million people who share a toilet or latrine with other households, and 892 million people mostly in rural areas who defecate in the open. Due to population growth, open defecation is actually increasing in parts of sub-Saharan Africa and Oceania.
The report further states that every year around 361,000 children under age 5 die due to diarrhoea, which is linked to contaminated water and poor sanitation conditions which are also linked to transmission of diseases such as cholera, dysentery, hepatitis A and typhoid.
