Two health workers at the hospital in western Uganda have died from Ebola in this outbreak.
Nationwide, 15 health workers have tested positive and six have died.
Intensive care staff work maximum eight-hour shifts and personnel from Ebola-free regions are rotated in, he said.
"There are facilities where doctors and health workers are still touching patients without gloves because they (gloves) are not there," Nahabwe said.
Case numbers remain low compared with a 2013-2016 Ebola outbreak in West Africa that killed at least 11,300 people.
