Longer secondary schooling substantially reduces the risk of HIV infection — especially for girls — and could be a very cost-effective way to halt the spread of the virus, according to researchers from Harvard T.H.

“These findings conﬁrm what has been fiercely debated for more than two decades—that secondary schooling is an important structural determinant of HIV infection and that this relation is causal,” said Ms. Jan-Walter De Neve, first author of the study and a doctoral student in the department of global health and population.
The study appeared online June 28, 2015 in The Lancet Global Health. Read more
