Fundación Huésped is an Argentine organisation with regional scope that has been working in public health since 1989, aiming to guarantee access to health and control of diseases. Based on a strategic planning process in which the institutional vision was broadened, we work focusing on HIV/AIDS, viral hepatitis, diseases preventable by vaccines and other transmisible diseases such as dengue and zika, as well as sexual and reproductive health.

Our main approach includes researching and developing practical solutions related to public health policies in our country and region. We also carry out massive, innovative and high-impact communication and prevention actions through a constant presence in media and social networks

What do we do?

What do we do?


We are a nationally and internationally renowned research center in HIV/AIDS, hepatitis and other transmissible diseases, and in training of healthcare resources. We design and coordinate national and international studies in which more than 3000 volunteer patients already participated in more than 160 clinical tests, according to ethical and scientific controls and to international policies and good clinical practices.

We represent Argentina in the international initiative for the cohort study (IEDEA) in the Central Caribbean and South American region (CCASAnet), an epidemiological study with more than 30.000 patients in the region. We are part of the IMPAACT network (HIV studies on pregnancy, pediatrics and adolescence) funded by the NIH (Health Institutes of the U.S.)

We carry out social-epidemiological researches and develop monitoring and evaluation tools to improve the current projects’ quality in every program.


We work for HIV/AIDS and Reproductive and Sexual Rights to be a standing item in the agenda, and for the information to be spread in an ethical and responsible way. We are a source of constant information and we serve the media demand looking for their commitment to the different issues.

We lead massive communication and prevention campaigns through innovative, high impact actions, in different channels of communication and focusing on the new technologies.

Institutional Development

We mobilize resources to ensure the sustainability of our activities and services, through three strategies:
– Fundraising: allows people to contribute with a monthly amount of money.
– Special events: with the aim of promoting our work and build bows with companies and laboratories to support our activities.
– National and International Cooperation: these financing strategies provide support in specific intervention and research programs.

Digital Innovation Lab

The Digital Innovation Lab designs and develops initiatives using technologies to improve health care and to promote sexual and reproductive rights.


We offer direct and free HIV, other transmissible diseases and sexual and reproductive rights care such as counseling and individual psychotherapy, meetings for groups of pairs of people with HIV, family and friends, adolescents and young , and serodiscordant couples. We provide counseling and legal advice in discrimination cases, provide support for his/her social and occupational inclusion and treatment retention. We have a rapid and free testing center in our headquarters.

We develop projects that promote participation and the exercise of the rights of the most vulnerable populations in different communities. The work is being developed alongside the public sector and civil society organizations, aiming to influence the public policies of the territory related to sexual and reproductive rights.

Our history

Our history

In Argentina, the first HIV cases appeared in 1982 and most of them were concentrated in the Juan A. Fernandez Hospital of the City of Buenos Aires. At that time, the hospital counted on only two infectious diseases physicians attending a couple of times a week, supplies were inadequate and treatments represented about a thousand dollars per month. In addition, it was a moment when stigma and discrimination was inflicted to those living with HIV and also to those who were trying to help them. The patients had no resources and the government was unable to give an answer to the situation. That is why in 1989 Fundacion Huesped was founded in order to coordinate the solidarity of all the people that was willing to help.

Almost immediately, Roberto Jauregui, the first person with HIV that made his status public in Argentina, joined the effort and worked tirelessly to install the theme. Roberto died in 1994 and, in his honor, Fundacion Huesped led the construction and donation of “Hospital de Dia Roberto Jauregui” to the Juan A. Fernandez Hospital where, since then, the Infectious Diseases Division provides care.

A few years later, thanks to the private donation of funds from family and friends of Robert Lebach, in 1997 we opened our own headquarters which allowed us to extend our activities to the dissemination of information, education, prevention and provision of services to people with HIV. Also, we were able to increase our activities of scientific and social research and training of human resources focused on health. During those years the Highly Active Antiretroviral Therapy (HAART) appeared and changed the history of the epidemic with modern and safer medications, which for many people meant the difference between life and death. With early detection and timely treatment, HIV became a chronic disease.

However, more than half of the people with HIV in Argentina were unaware of their status and more than a third of new diagnoses were given to people with advanced stages of infection, which reduced the effectiveness of treatment. This situation, although improved nowadays, remains an unsolved issue. Thus, the promotion of testing (especially in pregnant women to prevent vertical transmission) became one of our main goals in prevention and communication.

The pillar of our work since 2002 has been the support of vulnerable populations. We have implemented hundreds of projects in more than twelve departments of Greater Buenos Aires and other cities within the country considering HIV in the context of sexual and reproductive rights and other related problems of vulnerable populations. It is not possible to address HIV without considering early pregnancy, gender-based violence, and lack of access to health care for young people, lack of controls for the HIV pregnant women, among other realities that even today demand our attention. It was by seeing how stigma and discrimination work as channels for the epidemic that we decided to strengthen our actions of rights promotion, advocacy and communication, both nationally and in the region. The barriers in adherence to treatment, co-infections, hepatitis and other communicable diseases, and the development of simpler and more effective treatments are other aspects that lead our research and intervention work.
Today, the response to the epidemic has to face new challenges: the idea that the epidemic has been solved, the still persistent stigma and discrimination as well as the unbearable barriers to expand testing and treatment. It is clear that we cannot separate HIV from sexual and reproductive health and from other diseases.
Today, 25 years after those first steps, we have the goal by 2020 to be a foremost national organization with regional and international profile as leader in the areas of public health from a human rights perspective focusing on HIV/AIDS, other transmissible diseases and sexual and reproductive health. To be a leader organization in advocacy, clinical epidemiological and social research and training, and technologic dissemination of our capabilities, through strategic partnerships with the civil society, the state, the private sector and the academic field.
