Human immunodeficiency virus and related retroviruses.

Area of Science:

• Virology
• Molecular Biology
• Public Health

Background:

• Growing knowledge of human immunodeficiency virus (HIV) and related retroviruses necessitates standardized characterization.
• Discovery of new human and simian retroviruses highlights the need for rapid identification and public health response.

Purpose of the Study:

• To summarize current knowledge on the characteristics of HIV and related retroviruses.
• To introduce a proposed nomenclature system by the WHO working group for retroviral characterization.

Main Methods:

• Review of existing scientific literature on retroviral morphology, genetics, replication, and variability.
• Analysis of the proposed WHO nomenclature system for retroviruses, drawing parallels with influenza virus nomenclature.

Main Results:

• Comprehensive overview of basic characteristics, including genetic structure, biological properties, and replication mechanisms of HIV and related retroviruses.
• A practical and descriptive nomenclature system proposed by the WHO, offering insights into viral origins and types.

Conclusions:

• Standardized characterization and nomenclature are crucial for identifying new retroviral variants.
• The proposed WHO nomenclature system facilitates effective public health measures and understanding of retroviral evolution.
