The aids2031 Costs and Financing Project hosted a two-day Technical Review Meeting in Washington DC, attended by nearly 50 experts in economics, public health, and management. More than a dozen papers were presented and reviewed on AIDS resource needs and mobilization issues from now through 2031. The findings and recommendations from the papers will be used in the overall synthesis report, to be produced by Managing Director Rob Hecht and his R4D team later this year.
