GAT Grupo de Ativistas em Tratamentos

What GAT Grupo de Ativistas em Tratamentos does

GAT - Grupo de Ativistas em Tratamentos is a Portuguese community-based non-profit association founded in 1993 and headquartered in Lisbon, focused on HIV, viral hepatitis, STI prevention, and harm reduction for key populations. With 57 employees, it operates four dedicated community centers in the Lisbon Metropolitan Area: GAT Checkpoint LX (MSM), GAT IN Mouraria (people who use drugs), GAT Osvaldo/Intendente (sex workers, trans people, migrants, and homeless populations), and GAT Par a Par (peer case management for HIV, hepatitis, and tuberculosis), as well as a condom distribution program (Love Condoms) and an anti-discrimination center co-managed with Ser+. In July 2025, GAT added an Integrated Chemsex Support Service offering peer counseling, nursing, medical, and psychiatric consultations across multiple sites.

The organization's core technology is a peer-led, community-embedded service delivery model in which services are designed and delivered by members of the communities served, supported by trained clinical staff (nursing, medical, and PrEP consultations) and registered with Portugal's Entidade Reguladora da Saúde. Distribution runs through walk-in centers, apartment-based outreach, and presence at community events (Lisbon Pride, Global Support Don't Punish Day). All services are free, confidential, and frequently anonymous to users.

GAT does not generate commercial revenue; it is funded through Portuguese government entities (ACSS, ICAD, Instituto da Segurança Social, and the municipalities of Lisbon, Almada, and Seixal), international partners (AIDS Healthcare Foundation, Coalition Plus), and corporate sponsorship (Gilead Sciences for peer case management), supplemented by public donations. The organization has received repeated formal recognition from the WHO (2015, 2016), the ECDC (2013), and the EU Civil Society Forum on Drugs (2026), and its HIV screening program was validated as cost-effective by the Escola Nacional de Saúde Pública in 2015.

Direct peers

• Stop SIDA: Barcelona-based community NGO providing HIV/STI testing, PrEP access, and outreach for MSM and other key populations in Catalonia. Direct Iberian comparator to GAT Checkpoint LX.
• Deutsche Aidshilfe: German federal association of HIV/AIDS community organizations providing testing, counseling, harm reduction, and advocacy for MSM, PWID, migrants, and sex workers. Closely mirrors GAT's population-segmented center structure and peer-led approach.
• AIDES: France's largest community-based HIV/AIDS and hepatitis NGO, founded by people living with HIV. Operates testing centers, harm reduction programs, and advocacy for key populations — directly comparable to GAT's peer-led model and service mix in Portugal.
• Terrence Higgins Trust: UK's leading HIV charity operating community testing, PrEP support, and sexual health services for key populations. Comparable to GAT Checkpoint LX's MSM-focused testing and counseling model.
• Ser+: Portuguese community-based HIV/hepatitis organization co-promoting Centro Anti-Discriminação VIH with GAT since 2010. Directly comparable mission, beneficiary population, and Portuguese operating context.
• Fondazione LILA Milano: Italian community-based HIV/AIDS organization providing testing, peer support, and harm reduction services. Member of Coalition Plus alongside GAT, with similar peer-led, free-service model.

Broad incumbents

• Coalition Plus: International coalition of community-based NGOs fighting HIV and hepatitis. Coalition Plus is both a GAT funder and network partner; operates a portfolio of community organizations across multiple countries with overlapping service lines.
• AIDS Healthcare Foundation (AHF): Global HIV/AIDS services and advocacy organization. AHF is both a funder and operating partner of GAT (Love Condoms program); broader global footprint but overlapping mission and beneficiary populations.

Regional players

• APDES / Porto G project: Portuguese NGO operating harm reduction and community health services in Porto (northern Portugal). Comparable harm reduction model and key-population focus but in a different geographic market from GAT's Lisbon-centric footprint.

Peers

• CASO 95: No website confirmed in public sources. Luxembourg HIV/AIDS patient association providing peer support and community services. Comparable as a small European country-level peer organization serving PLHIV and key populations.
