Beyond Viral Suppression: Biological, Clinical, and Social Challenges in HIV Control

Abstract

While antiretroviral therapy (ART) has transformed HIV into a manageable chronic condition, the virus remains a persistent global health challenge. This review connects the biological foundations of HIV, including its zoonotic origins, the pandemic expansion of HIV-1 group M, and the genetic diversity generated by rapid replication, mutation, and recombination, with its clinical, epidemiological, and social consequences. We summarize the main routes of transmission, the HIV life cycle, current diagnostic approaches, and the mechanisms underlying modern antiretroviral therapy, while examining why epidemic control remains uneven across populations and regions. Regional disparities, delayed diagnosis, incomplete treatment access, and HIV-related stigma continue to disrupt prevention and long-term care. Finally, we discuss emerging strategies, including long-acting treatment and prevention, broadly neutralizing antibody-based vaccine approaches, cure research, and gene-editing technologies. Sustained HIV control will require not only biomedical innovation, but also equitable healthcare access, stigma reduction, and structural interventions that address persistent barriers to care.
