(DIAGNOSED_NAT) The percentage of adults and children living with HIV who know their status (have been diagnosed)

Export Indicator

The percentage of adults and children living with HIV who know their status (have been diagnosed)
Rationale

Diagnosed is the first 90 of the global targets. To ensure people living with HIV receive the care and treatment required to live healthy, productive lives, and to reduce the chance of transmitting HIV, it is critical that they know their status. In many countries, targeting testing and counselling at locations and populations with the highest HIV burden will be the most efficient way to reach people living with HIV and ensure they are aware of their status. This indicator captures the efficacy and coverage of HIV testing interventions.

This indicator is harmonized with GARPR indicator 1.5 (https://aidsreportingtool.unaids.org/static/docs/GARPR_Guidelines_2016_E...).

Numerator

Among people living with HIV, the number who know their HIV status

Denominator

The estimated number of adults and children living with HIV (PLHIV Estimate). Denominator is not collected as part of indicator, but rather is calculated as PLHIV_NAT numerator

Method of measurement

Numerator:

There are multiple methods to estimate the number of people living with HIV who know their status.

- Case-based surveillance

In countries with well-functioning HIV reporting systems, the number of people diagnosed can be estimated from national case-based data. The number of deaths among PLHIV must be subtracted from the cumulative number diagnosed to calculate the number of people living with HIV who know their status.

- Survey-based reporting

o Certain population-based surveys include questions about known HV status. Although this information may be subject to under-reporting bias, when combined with survey-related HIV testing it can provide an estimate of known status among survey respondents.

o Many population-based surveys include questions on HIV testing history. These questions can provide a range for the proportion of PLHIV with known status. The percentage of people living with HIV in the survey who have been tested in the past 12 months and received the results provides the upper range of known status (there will be a small proportion equal to the annual incidence rate –less than 2% in most cases – of people who might have converted in the 12 months after being tested). The percentage of people living with HIV in the survey who have ever been tested and received the results provides the lower range of known status.

When using survey-based methods, note that:

o Household surveys are often restricted to respondents of reproductive age (15– 49), and so may not be representative of people living with HIV <15 yearsand >49 years.

o Because household surveys are typically only done every five years, data from non-recent surveys may not reflect current levels of testing coverage.

Explanation of the numerator

Disaggregation: Disaggregated data is required. If data is available use the Age/ex disaggregates, if not available use the Sex disaggregate. Do not enter both.

- Sex: Male, Female

- Coarse Age/Sex Disag: Female<15, Male <15, Female 15+, Male 15+

Further information

Subnational reporting:

Subnational data will not be collected for FY16, but subnational collection will start for FY17 data collection.

Entered by

This data should be entered by the country team at the National level. Narratives should include the methodology used for determining sub-National data

Narratives

Narratives should include information on how the National estimates have been derived for both results and targets.
