The Centers for Disease Control and Prevention (CDC) is offering a cooperative agreement to support laboratory diagnosis and monitoring aimed at enhancing HIV/AIDS care and treatment services in Caribbean countries under the President's Emergency Plan for AIDS Relief (PEPFAR). The initiative focuses on strengthening laboratory systems, improving diagnostic capabilities, and expanding monitoring services for HIV, TB, and related diseases, building on previous successes in Jamaica and Trinidad and Tobago. Access to high-quality laboratory diagnostic services is crucial for effective public health programs, and this funding opportunity anticipates a total of $1,500,000 for the first year, with applications due by February 17, 2026. Interested applicants can reach out to the CDC at pepfarfoas@cdc.gov for further information.
