The outbreak started in western region of Kibaale in the East Africa nation in July. Some 300 people who were in contact with those who were infected are likely to still remain under observation.

"The cases are now confined only to Kibaale. The Ebola outbreak is now under control. But there is need to make follow-ups of the contact cases. Surveillance should be intensified over these cases because we can only be sure that they are safe after 21 days," Solomon Fisseha, WHO deputy head in Uganda, told dpa.

The outbreak had forced hundreds of schools to close and in the worst affected areas even social gatherings were banned.

This is the fourth outbreak of Ebola in the country since 2000, when it killed 224 people.

About 40 people died of the disease in villages along the border with the Democratic Republic of Congo in 2008, while another isolated death occurred last year.

Ebola, which has no known cure, is highly infectious and symptoms include vomiting, diarrhea and external and internal bleeding. It was first identified in 1976 in Congo near the River Ebola.Author: Henry Wasswa
