Good afternoon, I'm hoping someone can possibly fill our request for these two articles. They are referenced in an article as: World Health Organization, 2011: Lassa Fever in Ghana. World Health Organization Regional Office for Africa Outbreak Bulletin 1, 4 World Health Organization, 2011: Lassa Fever, Yellow Fever and Cholera in Ghana. World Health Organization Regional Office for Africa Outbreak Bulletin 1, 3. I can't seem to find any publication by that title. It is possible that the publication is actually titled Outbreaks and Emergencies Bulletin. I have contacted the Regional Office for Africa Library, but have not heard anything back yet. Please help!
