Summary
HIV partner services effectively notify partners and identify new infections. However, HIV testing rates among notified partners remain low, highlighting a critical gap in ending the HIV epidemic.
Area of Science:
- Public Health
- Epidemiology
- Infectious Disease Control
Background:
- Human immunodeficiency virus (HIV) partner services are crucial for HIV prevention and care.
- Understanding factors influencing partner notification, testing, and positivity is essential for program improvement.
Purpose of the Study:
- To examine factors associated with partner notification, HIV testing, and HIV positivity among partners of HIV-diagnosed individuals.
- To assess the effectiveness of CDC-funded state and local health department partner services.
Main Methods:
- Analysis of partner service data from 61 health departments (2013-2017).
- Multivariate Poisson regression used to assess associations between outcomes and index/partner characteristics, region, and service year.
- Matched data from 33,524 index persons and 51,368 partners.
Main Results:
- 97.2% of notifiable partners were notified; 52.3% were tested for HIV.
- 23.8% of notified and tested partners received a new HIV diagnosis.
- Partner notification, HIV testing, and positivity were linked to index/partner characteristics, region, and service year.
Conclusions:
- CDC-funded partner services effectively notify partners and identify undiagnosed HIV infections.
- Low HIV testing rates among notified partners represent a significant gap.
- Strategies to improve HIV testing are needed to help end the HIV epidemic.

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...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

12.8K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:10Retrovirus Life Cycles
47.6K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
