Prevalence of HIV infection in conflict-affected and displaced people in seven sub-Saharan African countries: a...

Area of Science:

• Epidemiology
• Public Health
• Conflict Studies

Background:

• Conflict and violence are often presumed to exacerbate HIV epidemics.
• The impact of conflict, displacement, and sexual violence on HIV prevalence remains a critical public health question.

Purpose of the Study:

• To investigate the relationship between conflict and HIV prevalence in sub-Saharan Africa.
• To compare HIV rates in conflict-affected populations versus unaffected populations.
• To assess HIV prevalence in refugees compared to their host communities.

Main Methods:

• Systematic literature search of Medline and Embase for HIV prevalence data.
• Inclusion of original data from seven conflict-affected countries in sub-Saharan Africa.
• Evaluation of survey data for HIV sentinel surveillance and population-based studies.

Main Results:

• No increase in HIV prevalence was observed during conflict periods in the selected countries.
• Urban HIV prevalence decreased in conflict-affected areas similarly to unaffected areas.
• Most refugee camps had lower or similar HIV prevalence compared to host communities.
• No data supported that rape increased population-level HIV prevalence.

Conclusions:

• Current data are insufficient to confirm that conflict, displacement, or rape significantly increases HIV prevalence.
• There is a need for better mechanisms to collect timely information on HIV incidence in conflict zones.
• The assumption that refugees spread HIV infection requires further investigation.
