Yearly data from 1990 to 2024, from the World Bank.
Gabon's prevalence of HIV, total (% of population ages 15-49) was 2.8% in 2024, the latest year in the World Bank's World Development Indicators. That is down 1.2 percentage points from 4% in 2014.
| Value | Year | |
|---|---|---|
| Latest | 2.8% | 2024 |
| Five years earlier | 3.4% | 2019 |
| Ten years earlier | 4% | 2014 |
| Highest | 4.8% | 2001 |
| Lowest | 1.3% | 1990 |
| Average since 2015 | 3.36% | 2015–2024 |
| First recorded | 1.3% | 1990 |
Over five years it is down 0.6 percentage points from 3.4% in 2019. Since 1990 it is up 1.5 percentage points from 1.3% in 1990.
In 2024, Gabon's prevalence of HIV, total (% of population ages 15-49) fell 0.1 percentage points on 2023 (from 2.9% to 2.8%).
Across the 30 yearly changes before that (1994 to 2023), the average change was +0.02 percentage points and a typical year strayed about 0.2 percentage points from that (the standard deviation). This year's change was 0.6 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.
On record, the biggest yearly rise was 0.5 percentage points in 1994 and the biggest yearly fall was 0.2 percentage points in 2019. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.
From 2015 to 2024 the straight-line trend is downward, about 0.13 percentage points a year. A straight line explains 99% of the movement over 10 observed years.
Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.
Extending that straight line gives about 2.46% for 2027. We show this only because the same method, fitted on earlier years, predicted 2022 to 2024 better than "no change" would have: its average miss was 0.15%, against 0.3% for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

In 2024, Gabon had the 14th highest value of the 147 economies reporting that year. Higher is not always better: for some indicators the lowest value is the one to aim for. See the full ranking.

Prevalence of HIV refers to the percentage of people ages 15-49 who are infected with HIV.
Limitations: The limited availability of data on health status is a major constraint in assessing the health situation in developing countries. Surveillance data are lacking for many major public health concerns. Estimates of prevalence and incidence are available for some diseases but are often unreliable and incomplete. National health authorities differ widely in capacity and willingness to collect or report information.
Regional and income-group figures are computed by the World Bank as a weighted average.
