Rumbek Diakonie Health Care Pharmaceutical Manager revealed numerous outbreaks of diseases including diarrhea and malaria among others.
Paul Alambany told Good News Radio on Monday that the Center received many patients.
Mr Alambany advised the public to use clean water, clear their environment and use toilets instead of defecating in open places.
He said the mid December crisis resulted to shortage of drugs due to breakdown of coordination between the health NGOs and donors.
Mr Alambany said Diakonie Healthcare Center was forced to give half a dose to patients in order for all of them to get treatment.
