January2010 - Haiti hit by a magnitude 7 earthquake, one of the poorest countries in the world, where 60% of the population lives on less than USD 2.50 a day
After the earthquake, hundreds of thousands of homeless people were housed in makeshift camps, causing a cholera outbreak in October 2010
The disease was introduced by Nepalese soldiers, an example of relocation diffusion
Between October 2010 and November2014, nearly 720,000 cholera cases were recorded, with 8700 deaths
The British Red Cross delivered clean drinking water to 300,000 people living in camps in Port-au-Prince
The British Red Cross built 1300 toilets for 250,000 people
The British Red Cross provided medical supplies to the main hospital in Saint Marc
The British Red Cross treated 18,700 cases of cholera in treatment units in the La Piste camp in Port-au-Prince
The British Red Cross raised awareness among young people on how to avoid infection and of the symptoms of cholera
The UN admitted their role in the outbreak in 2016, due to leaking sewage pipes at a UN base
In January 2012, Partners in Health introduced a cholera vaccine, but some public health advocates said that due to multiple doses being needed for so many people, it would be impossible to stop the outbreak
WASH (Water, Sanitation, Health) facilities could cost upwards of USD 1 billion which was too expensive for Haiti, and the building would take too long
However, without WASH facilities, cholera would keep coming back
The lack of effective government in Haiti in October2010 also caused the high amount of deaths
Six months after the outbreak there was just one operational waste management site in Port-au-Prince, a city of 3 million people
