OPP-ERA – Improve monitoring of people living with HIV in Guinea through increased access to viral load



Accès à la mesure de la charge virale


In most resource-limited countries, the follow-up of patients on antiretroviral therapy is mainly based on clinical examination and CD4 count. However, these tools are insufficient to identify and prevent situations of therapeutic failure. This limit leads to unnecessary or too late switching to rarer and more expensive second line treatments. The use of HIV viral load (CV) measurement is necessary to ensure appropriate treatment. In Guinea, viral load testing was not available in the public health system.


Start: February 2013

Closure: July 2019

Countries of Intervention : Guinea, Cameroon, Burundi,Côte d’Ivoire

Co-funded by : UNITAID, ANRS

Beneficiaries : Comité de Pilotage :PNPCSP
DNPL : Direction Nationale de la Pharmacie et du Laboratoire
Laboratoire National de Santé Publique (LNSP)
Comité Médical Technique (CMT)
Direction de l'Hôpital National de Donka



The OPP-ERA project was built to contribute to the global strategy to end HIV/AIDS in the World, particularly the “3rd 90” of the UNAIDS targets 90-90-90: to reach 90% of patients on antiretroviral treatment who have an undetectable viral load by 2020. The OPP-ERA project has thus contributed to improving regular access and use of viral load testing in 4 countries in West and Central Africa.

The project was supported and financed by Unitaid, implemented by a consortium, led by Solthis, responsible for the project operational coordination and implementation in Guinea; ANRS as co-funder and head of the scientific coordination; Expertise France responsible for project implementation in Côte d’Ivoire and Cameroon; and Sidaction in Burundi.


Activities and Results 

From 2013 to 2019, the OPP-ERA project increased access to viral load testing and integrated them into the health systems of the four countries of intervention by creating necessary conditions: functional molecular biology units, trained health personnel, continuous availability of the health products needed to achieve the viral load, systems for collecting samples and reporting organized results, health authorities involved and patients involved in their health. Find out more by watching the webdocumentary below :



  • 12 equiped laboratories with  molecular biology technologies
  • 300 health professionals trained ( clinicians, biologists, laboratory technicians, procurement and stocks managers)
  • More than 75% of patients with undectectable viral load ( and up to 88% of undectable viral load in certain health centers)
  • More than 180 000 viral load tests realized.
