Abstract

Insights

HIV-positive men who have sex with men and women (MSMW) who inject drugs engage in higher-risk sexual behaviors, particularly with female partners. Targeted prevention is crucial for this population.

Area of Science:

  • Public Health
  • Infectious Disease Epidemiology
  • Behavioral Science

Background:

  • Limited research exists on HIV transmission risk behaviors among HIV-positive injection drug users (IDUs) who are men who have sex with men and women (MSMW).
  • Understanding these behaviors is critical for developing effective HIV prevention strategies.

Purpose of the Study:

  • To compare the HIV transmission risk behaviors of HIV-positive MSMW with those of men who have sex exclusively with women (MSW) and men who have sex exclusively with men (MSM).

Main Methods:

  • Utilized baseline data from the Intervention for Seropositive Injectors-Research and Evaluation (INSPIRE) study, a multi-city randomized controlled trial.
  • Compared unprotected sexual behaviors and transactional sex prevalence among MSMW (n=118) against MSW (n=469) and MSM (n=90).

Main Results:

  • MSMW reported significantly higher rates of unprotected vaginal and anal sex with HIV-negative/unknown status female partners compared to MSW.
  • MSMW showed similar rates of unprotected insertive anal sex but lower rates of unprotected receptive anal sex with HIV-negative/unknown status male partners compared to MSM.
  • MSMW were more likely to engage in transactional sex than both MSW and MSM.

Conclusions:

  • Further investigation is needed to understand the specific contexts of unprotected sex among HIV-positive injection drug-using MSMW.
  • Prevention programs must address the unique needs of this population, with a particular focus on risks associated with female partners.

Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

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...

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Genital Herpes01:23

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Retrovirus Life Cycles01:10

Retrovirus Life Cycles

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 retrovirus to...
