Hypothesis
What is the prevalence of HIV-2 infection and dual reactivity in patients in Gabon?
Conclusion
The study found a high prevalence of HIV-2 infection and dual reactivity among patients in Gabon.
Supporting Evidence

- 96.0% of HIV-positive sera were exclusively HIV-1-positive.
- 4 patients were exclusively HIV-2-positive.
