What is the global prevalence of HIV?

The global prevalence of HIV (Human Immunodeficiency Virus) remains a significant public health concern. The prevalence can change over time due to various factors, including new infections, advancements in treatment, and prevention efforts. Here is a general overview:

- Global Estimates (UNAIDS, 2020):
  - In 2020, it was estimated that approximately 37.7 million people were living with HIV globally.
  - Sub-Saharan Africa remains the most affected region, accounting for the majority of HIV infections.

- New Infections:
  - The number of new HIV infections has been decreasing globally, but certain regions and populations continue to face higher risks.

- Access to Treatment:
  - Access to antiretroviral therapy (ART) has expanded, contributing to improved health outcomes for many individuals living with HIV.

It's important to note that these figures are subject to change, and updated statistics may be available from reputable sources such as UNAIDS (Joint United Nations Programme on HIV/AIDS) or the World Health Organization (WHO). The global response to HIV involves a combination of prevention, testing, treatment, and support services aimed at reducing new infections and improving the quality of life for those affected by the virus.
