Ugandan authorities have begun a clinical trial of a vaccine against the Sudan strain of Ebola that has killed one person in the outbreak declared last week.

Ugandan authorities launched a clinical trial of a vaccine against the Sudan strain of Ebola that has killed one nurse in the capital, Kampala.

Uganda has begun a trial vaccination programme for the strain of Ebola viral infection that is behind the country's latest outbreak, according to the World Health Organization (WHO), while the number of confirmed cases has risen to three.

After the first Ebola death in Uganda in years, a senior health official says authorities in the African nation are "in full control of the situation."

This is a critical achievement toward better pandemic preparedness and saving lives when outbreaks occur,” said Dr. Tedros Adhanom Ghebreyesus, WHO Director-General.

Uganda has confirmed an outbreak of the Ebola virus in the capital Kampala with the first confirmed patient dying from it on Wednesday, the health ministry said on Thursday. It is the East African country's ninth outbreak since it recorded its first infection of the viral disease in 2000.

Ugandan officials confirmed an Ebola outbreak in the east African country's capital, Kampala, last week. One nurse died on Jan. 29, and Ugandan authorities have confirmed two other Ebola cases as of the announcement of the outbreak.

After a nurse died of the Ebola virus, the country has declared Ebola outbreak and is now deploying vaccine against the Sudan strain of the virus.
