The United Nations says about 2,400 cases of Cholera and 37 deaths have been reported in in South Sudan since the outbreak of the disease in May this year.

The Office for the Coordination of Humanitarian Affairs says six counties have been much affected, with Fangak being the latest to have confirmed cases.

OCHA says the number of affected areas have increased compared to that of 2015 when there was a similar outbreak of Cholera.

The areas include Juba,Terekeka, Duk, Fangak, Pageri in the former Eastern Equatoria and Awerial in former Lakes. The 2015 outbreak was confined to Juba and Bor Jonglei.

The UN-OCHA says the outbreak in Awerial, which began at Mingkaman IDP camp, has spread to the host community, with four cases, including one death reported in Kalthouk.

OCHA says Juba is the worst affected area in 2016, with males accounting for 56.3 per cent of the cases while females make up 43.7 per cent.

It says the spike in conflict in July and subsequent displacement contributed to the spread of cholera and left many people with inadequate sanitation facilities and insufficient access to clean water.

People exposed to the disease carried it to new areas as they fled.

OCHA says continued population movement due to the ongoing conflict in the Greater Equatoria has spread the disease further to other locations and across the border to the refugee camps in Uganda.

IDP camps reporting cases include UN camp in Tongping, Gorom refugee camp, Mahad, Mangatain and Gumbo in Juba, and Nimule.

To contain the outbreak, OCHA says health and WASH partners have set up cholera treatment centres and oral rehydration points in the affected counties.

The UN-OCHA says the toll free line is open for the public to report cases and get information, the number is 1144.
