Human Virome01:26

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Area of Science:

  • Public Health
  • Infectious Disease Epidemiology
  • Global Health Initiatives

Background:

  • New strategies and rapid testing technologies offer opportunities to achieve global HIV testing targets.
  • Despite advancements, significant obstacles to widespread HIV testing persist, including inequitable access within and across nations.

Purpose of the Study:

  • To review the current landscape of HIV testing, identify persistent challenges, and outline future directions for expanding testing services.
  • To emphasize the public health imperative of routine HIV screening and widespread testing to meet national and international goals.

Main Methods:

  • Literature review of recent advancements in HIV testing approaches and technologies.
  • Analysis of existing data on HIV testing coverage and awareness of status globally, with a focus on disparities.
  • Identification of policy and programmatic challenges related to testing high-risk populations, children, and adolescents.

Main Results:

  • While approximately 80% of individuals with HIV are aware of their status in the U.S., a majority in Africa remain unaware.
  • Significant disparities in HIV testing coverage exist both within and between countries.
  • Unresolved policy and programmatic challenges impede testing among key populations, including at-risk groups, couples, children, and adolescents.

Conclusions:

  • Future HIV testing strategies should prioritize rapid testing, acute HIV infection detection, self-testing, and partner notification.
  • Expanded routine HIV screening and widespread testing are essential public health actions to achieve global HIV prevention and treatment objectives.
