As Ebola continues to burn its way through three West African countries, the World Health Organization on Wednesday elected its next Africa director, a doctor from Botswana who is a longtime veteran of the U.N. agency. WHO's next Africa director, Matshidiso Moeti, was the Africa deputy regional director until March. WHO announced the discovery in Guinea of the current Ebola outbreak on March 23. The circumstances of her departure from WHO were not immediately clear. After the election results were announced in a WHO meeting in Benin, Moeti expressed optimism that the outbreak will be under control within three months.
