HIV ART Coverage by Country: 2026 Snapshot Based on UNAIDS 2024 Estimates

What ART Coverage Measures

ART coverage measures the share of the estimated population living with HIV that is receiving antiretroviral therapy. WHO defines the numerator as adults and children living with HIV who are receiving ART and the denominator as the estimated number of adults and children living with HIV.

This is not the second 95 of the 95–95–95 cascade. The second 95 uses people who know their HIV-positive status as its denominator. The indicator ranked here uses all people living with HIV, including people who may not yet know their status.

A high percentage indicates broad treatment reach relative to the estimated population living with HIV. It does not directly measure viral suppression, treatment adherence, retention in care, drug resistance, HIV incidence, HIV prevalence or the absolute size of the national epidemic.

Top 10 Countries by ART Coverage in 2025

Botswana leads with a published estimate above 98%. São Tomé and Príncipe and Saudi Arabia are next at 97%, followed by Lesotho at 96%. Seven of the ten highest-ranked countries are in Eastern and southern Africa.

Top 10 confirmed 2025 country estimates

Ranking is descending by the published 2025 estimate. Countries with the same published whole-percentage value are ordered alphabetically. Botswana is shown as >98% exactly as published by UNAIDS.

Methodology

Source hierarchy: the UNAIDS 2026 estimates workbook controls the country values; the UNAIDS 2026 global fact sheet supplies the global treatment benchmark; WHO Global Health Observatory metadata is used for the indicator definition and denominator. Supporting sources are not averaged into the country values.

Ranking method: published estimates are sorted from highest to lowest. Countries sharing the same whole-percentage estimate are ordered alphabetically, ignoring diacritics for tie-breaking only. This tie-break does not imply that one tied country has better underlying coverage than another.

UNAIDS reports Botswana's 2025 ART coverage as >98% without publishing a more precise percentage. The ranking therefore shows the value exactly as reported. Every other included 2025 estimate is 97% or lower.

The median of the 127 included country estimates is 73%. The global benchmark is 78%, but a simple unweighted country median should not be compared with the global figure as if both were calculated the same way: WHO and UNAIDS global estimates are population-weighted rather than an average of country percentages.

Limits: the denominator is estimated, published values are rounded, and national estimates can be revised when surveillance, programme or modeling inputs change. ART coverage does not measure viral suppression, adherence, treatment quality, equity between population groups, incidence, prevalence or AIDS-related mortality.

ART coverage among all people living with HIV, official 2025 UNAIDS estimates

All table values come from the UNAIDS 2026 estimates workbook and refer to 2025. Regional categories follow the workbook's reporting sequence; Antigua and Barbuda, Saint Kitts and Nevis, and Saint Lucia are grouped with the Caribbean for filtering. This category assignment does not alter their source values or ranks.

Insights From the 2025 Ranking

What the Ranking Means

This ranking is useful for comparing treatment reach, but it is not an overall ranking of national HIV programmes or health systems. Countries can reach similar ART coverage while differing substantially in diagnosis, retention, viral suppression, prevention, financing and access for key populations.

Small gaps should be interpreted cautiously. Country estimates are rounded and depend partly on estimates of the number of people living with HIV. A difference of one percentage point does not establish a meaningful performance gap when uncertainty and later revisions are taken into account.

The ranking also should not be read as the second 95 of the 95–95–95 targets. This table uses all people living with HIV as the denominator. Treatment among people who know their status and viral suppression among people on treatment are separate indicators.
