How human immunodeficiency virus voluntary testing can contribute to tuberculosis control

Area of Science:

• Public Health
• Infectious Disease Epidemiology
• Global Health

Background:

• Human immunodeficiency virus (HIV) significantly exacerbates the tuberculosis (TB) epidemic, particularly in sub-Saharan Africa.
• Historically, public health responses to HIV and TB have operated in silos, despite their strong epidemiological connection.
• The World Health Organization (WHO) advocates for integrated strategies to reduce the burden of HIV-related TB.

Purpose of the Study:

• To explore how voluntary counseling and testing (VCT) for HIV can foster a more unified public health response to TB.
• To assess the potential of VCT as an entry point for comprehensive HIV and TB interventions.
• To evaluate the ProTEST Initiative's role in linking VCT services with TB prevention and care.

Main Methods:

• The ProTEST Initiative, coordinated by WHO, promotes VCT as a gateway to intensified TB case-finding and isoniazid preventive therapy.
• Pilot districts are establishing connections between VCT centers and TB prevention/care services.
• This initiative aims to operationalize a broad range of interventions for TB control in high HIV prevalence settings.

Main Results:

• VCT for HIV offers significant benefits to TB patients, including referral for clinical care and support for HIV-positive individuals.
• Individuals utilizing VCT services can benefit from TB screening, leading to timely treatment for active TB or preventive therapy for latent TB.
• Linking VCT with TB services facilitates access to essential interventions for both conditions.

Conclusions:

• Integrating VCT into TB programs is crucial for a coordinated public health response to the dual HIV/TB epidemic.
• The ProTEST Initiative demonstrates a viable model for linking VCT with TB prevention and care services.
• This integrated approach is essential for controlling TB in regions heavily impacted by HIV.
