HIV-1 Recent Infection Surveillance

UCSF supports NASHCoP in the overall coordination of and technical guidance on HIV-1 Recent Infection Surveillance in Tanzania. As Tanzania moves closer to reaching 95-95-95, monitoring of recent HIV infections will allow us to target public health response to sub-populations and locations where high levels of transmission may be occurring. Data from recent HIV infection surveillance, along with HIV program data and other surveillance data, can help identify geographic areas, demographic groups, or subpopulations at risk of HIV infection and inform appropriate public health responses.

 

Activities that UCSF has implemented and continues to support in its coordination and technical assistance role for Recency Surveillance include:

 

  • Development and support of an HIV-1 recency surveillance dashboard that displays key analyses of recency surveillance data. This allows stakeholders to monitor the performance of recency surveillance and provides access to meaningful analyses to promote data use.
     

  • Storage and distribution of Asante Test Kits for the implementation of recency surveillance throughout the country, as well as monitoring consumption and forecasting commodities needs.
     

  • Development of standardized training materials, data collection tools, job aids, and SOPs to support the implementation of recency throughout the country.

Zanzibar Integrated Biological and Behavioral Assessment (IBBS) 2023

UCSF, in collaboration with the Zanzibar Integrated HIV, Hepatitis, TB, and Leprosy Programme (ZIHHTLP) conducted a fourth round of bio-behavioral surveillance among men who have sex with men, people who inject drugs, and female sex workers, in Unguja, Zanzibar. The survey aimed to estimate the prevalence of HIV among PWID, MSM, and FSW in Zanzibar, estimate progress towards UNAIDS 95-95-95 targets, and estimate the population sizes.
​
Secondary objectives included:

  1. Estimate the prevalence of hepatitis B, hepatitis C, and syphilis antibodies

  2. Estimate CD4 count among those living with HIV

  3. Estimate HIV viral load suppression among those living with HIV

  4. Identify and characterize risk behaviors, sexual and drug use networks, and experiences of violence and discrimination

  5. Assess health seeking behaviors

  6. Assess uptake of HIV prevention, care, and treatment services as they relate to the 95-95-95 cascade, including those targeting key populations

  7. Estimate HIV incidence

 

UCSF and ZIHHTLP also conducted a Rapid Assessment among the same populations in Pemba Island. The objectives of the rapid assessment were to:

  1. Estimate the positivity of HIV, hepatitis B, and syphilis

  2. Identify and characterize basic risk behaviors.

  3. Understand the context in which HIV risk behaviors take place.

  4. Gather data to inform future surveillance activities.

  5. Estimate the population size.

 

Findings from this activity will be presented at the IAS 2024 conference.
