Health Desk-- 2nd June, 2017: The number of children dying worldwide of diarrhoea fell by a third between 2005 and 2015, researchers have found.
The Lancet study says better access to clean water and sanitation is key, with fewer weak and malnourished children becoming infected.
New vaccines have also had a positive impact.
However, diarrhoea is still the fourth-biggest killer of children globally, with almost 500,000 a year dying before their fifth birthday.
This figure could well be a significant under-estimate because of the lack of data in sub-Saharan Africa, where most cases occur.
