HIV and TB in the context of universal access: What is working and what is not? - Report of an international open consultative meeting held in ...
Summary
A   meeting was co-organized by the World Health Organization (WHO), the Joint United Nations
    Programme on HIV/AIDS (UNAIDS), the International AIDS Society, the Treatment Action
Group and the Forum for Collaborative HIV Research on behalf of the Global TB/HIV Working
Group of the Stop TB Partnership in conjunction with the XVI International AIDS Conference in
Toronto, Canada, on 12–13 August 2006. The objective of the meeting was to accelerate an effective
and joint response to the epidemic of HIV-related tuberculosis (TB) by facilitating the sharing of
information and experiences, networking and strengthening the partnership between TB and HIV
(human immunodeficiency virus) communities in a forum environment. Lively and interactive dis-
cussion was promoted by a very successful marketplace, where participants presented and promoted
their experiences, results, views, opinions and country-level findings in poster and display formats.
The meeting was attended by almost 300 participants, mainly representing the HIV community, who
were also attending the International AIDS Conference. A tribute was paid to Dr Lisa Onyemobi,
WHO TB/HIV National Professional Officer in Nigeria, who died suddenly earlier in 2006. The meet-
ing was followed by a TB/HIV satellite symposium on the afternoon of 13 August 2006, which was
held as part of the International AIDS Conference. The International AIDS Society, Forum for Col-
laborative HIV Research, co-organized the satellite symposium with the Stop TB and HIV Depart-
ments of WHO.
