Yellow fever outbreak slows down in Angola Latest figures from the World Health Organization indicate that the yellow fever outbreak which started in Angola has slowed down. The outbreak was first detected in the capital Luanda in December. In May scientists in the US warned that the shortage of yellow fever vaccines could spark a global health emergency. But the report says a new case of yellow fever has not been recorded since June in Angola, and July in Democratic Republic of Congo. It added that this shows surveillance is functioning well but warns that it is still possible that detection of a case could be delayed in remote areas. OURCE: BBC
