HIV-1 Non-Group M Strains and ART.

Area of Science:

• Virology
• Epidemiology
• Infectious Diseases

Background:

• Global HIV infection elimination requires comprehensive strategies including epidemiological surveillance, prevention, and therapeutic management.
• Atypical human immunodeficiency virus type 1 (HIV-1) non-group M variants present unique challenges due to genetic divergence, impacting treatment efficacy and patient management.
• Current UNAIDS targets for screening, treatment, and efficacy are essential but must encompass these less common HIV-1 variants for complete eradication.

Purpose of the Study:

• To provide an updated overview of the epidemiology, diagnosis, and antiretroviral treatment efficacy for HIV-1 non-M variants.
• To highlight the importance of addressing genetic diversity within HIV-1 to achieve global elimination goals.
• To inform strategies for managing and controlling the spread of non-group M HIV-1 strains.

Main Methods:

• Literature review and synthesis of recent research findings on HIV-1 non-M variants.
• Analysis of epidemiological data concerning the prevalence and distribution of non-M HIV-1 subtypes.
• Evaluation of current diagnostic methods and antiretroviral drug efficacy against diverse HIV-1 genetic forms.

Main Results:

• Recent data suggest that eliminating HIV-1 non-M variants is achievable with continued vigilance and surveillance.
• Genetic divergence in non-M variants has historically impacted antiretroviral treatment effectiveness.
• Emergence of more divergent and resistant forms necessitates ongoing monitoring.

Conclusions:

• Achieving the 2030 HIV elimination goal necessitates specific attention to HIV-1 non-M variants.
• Effective management of HIV-1 non-M variants requires integrated epidemiological, diagnostic, and therapeutic approaches.
• Sustained surveillance is critical to prevent the emergence of drug-resistant HIV-1 strains.
