Outbreak of Rare Ebola Strain Declared in Uganda

KAMPALA, Uganda—Uganda declared an outbreak of a relatively rare strain of the Ebola virus on Tuesday, raising concerns of a wider spread because existing vaccines are unlikely to provide quick protection against this version of the virus.

A 24-year-old man who died Monday in central Uganda was found to have been infected with the Sudan strain of Ebola, said Diana Atwine, permanent secretary at Uganda’s Health Ministry.
