Medicines Sans Frontier or MSF cautions South Sudanese people to have high alert on cholera because flies can easily contaminate water or food.
Assistant Medical Coordinator, Makuir Mayom, calls on people to build latrines and boil drinking water.
He advises South Sudanese to wash their hands with soap or ash before eating or after visiting latrines to eradicate cholera.
The Assistant Coordinator concerns came during a cholera vaccination campaign in Newsite after new suspected cases of the disease were reported in Juba Teaching Hospital.
Mayom says MSF is carrying out the campaign, targeting eleven thousand people in Newsite and New Bongo areas.
He confirms that new cases came as a result of drinking dirty water and open defecation.
Amou Gabriel Deng, a 15-year-old pupil of Dr John Garang Bilpam Primary School, who received the vaccine says it is important to protect herself.
She advises other people to receive the vaccine to prevent them from getting cholera.
MSF in collaboration with the national Ministry of Health and WHO conducted the vaccination campaign.
MSF conducted a mass cholera vaccine in Juba two months ago.
It says after the mass vaccination two months ago, thirty new cases have been reported in neighborhoods that were unvaccinated.
