title: Complement-fixing antibodies against cytomegalovirus in different parts of the world.
abstract: A WHO cooperative study in which 27 laboratories participated showed that the distribution of cytomegalovirus antibodies in healthy blood donors varies widely, ranging from 40% in highly industrialized areas to 100% in developing countries. Climatic factors did not appear to play an important role in the spread of the virus.
