HIV Spreads Faster Just Before Violent Conflict: Study

The rate of new HIV infections rises significantly in the five years leading up to a conflict or bloodshed in a country, according to new study of the relationship between violent conflict and HIV incidence in 36 sub-Saharan Africa countries.
"It implies that there is something going on in social, political, and health care environments in those years that are conducive to HIV spread," said lead author Brady Bennett, from The Brown University in US.
Prior studies examining how war may affect the HIV (human immunodeficiency virus) epidemic have produced mixed, and even conflicting, results, said senior author Mark Lurie, associate professor of epidemiology in the Brown University School of Public Health.
Mr Lurie and Mr Bennett worked together to produce a more comprehensive data set than had existed before and to conduct more rigorous analysis than had previously been done.
The new study tracked HIV incidence statistics in 36 sub-Saharan countries from 1990 through 2012 and correlated them with periods of conflict and peace in each country.
The research team was therefore able to calculate how the incidence rose and fell in each country in relation to violence, while controlling for other factors such as economic development, refugee influx, and the year of the region's broader epidemic, which generally peaked in 1996.
Compared to times of peace, the analysis showed, HIV incidence increased by 2.1 infections per 1000 people a year in the five years before a conflict where at least 25 people died as a result of fighting.
