Abstract
In Feb. 1980, blood samples from 91 women and their newborn babies (cord blood) from Mali were analyzed for influenza and coronavirus OC 43 HI [hemagglutination inhibition] antibodies. The titers of influenza HI antibodies were higher in blood samples collected from the mothers at delivery than in their newborns. GMT [geometric mean titer] values and percentage of persons with protective titers (.gtoreq. 1:40) indicated that influenza A (H3N2) viruses had been highly active in Mali. Influenza A (H1N1) and B activity were minor. The prevalence of OC 43 coronavirus HI antibodies was higher in the babies (95%) than in their mothers (75%).
