The Ugandan health minister Dr. Christine Ondoa said that the outbreak was not initially detected because patients did not show typical symptoms of infection by the lethal virus. The infected had fevers and were vomiting, but the telltale hemorrhaging was missing, according to CNN.
A team of experts from the U.S. Centers for Disease Control and Prevention, the Ugandan Health Ministry and the World Health Organization recently arrived in Kibaale, a district located in the midwestern portion of Uganda.
The non-profit organization Medecins Sans Frontieres is also in Kibaale, where it is setting up an isolation center at the local hospital.
Health officials are still trying to determine the full extent of the outbreak. Ondoa said nine of the deaths came from one household in the village of Nyanswiga. A medic who was treating the victims has also died from the infection. The medic’s sister was also infected, but remains hospitalized and in stable condition, CNN reports.
Ondoa described the Ebola-Sudan strain identified as responsible for the outbreak. She said it was mild in comparison to other types of Ebola and said that lives could be saved with timely intervention.
