Retrovirus Life Cycles01:10

Retrovirus Life Cycles

42.7K
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...

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

5.0K
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...

Sexually Transmitted Infections

1.8K
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 II: Airborne and Protective Environment

2.0K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Healthcare Associated Infections II: Preventive Measures

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.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Area of Science:

  • Infectious Diseases
  • Public Health
  • Pharmacology

Background:

  • Human immunodeficiency virus (HIV) infection rates are increasing, necessitating enhanced prevention strategies.
  • Post-exposure prophylaxis (PEP) involves short-term antiretroviral therapy (ART) to mitigate HIV acquisition risk post-exposure.
  • Nonoccupational PEP (PEPSE), primarily for sexual exposure, is vital for comprehensive HIV prevention.

Purpose of the Study:

  • To review current evidence and guidelines for the use of PEPSE in HIV prevention.
  • To assess HIV transmission risk, indications, drug regimens, and patient management for PEP.
  • To explore PEP's role alongside treatment as prevention and pre-exposure prophylaxis in reducing HIV incidence.

Main Methods:

  • Review of current evidence on PEPSE efficacy and safety.
  • Analysis of national and international PEPSE guidelines.
  • Examination of recent interventional and observational studies on ART's impact on HIV transmission.

Main Results:

  • PEPSE is a critical component of HIV prevention, requiring increased awareness among clinicians and eligible individuals.
  • Effective ART in HIV-positive partners significantly reduces transmission risk within serodiscordant relationships.
  • Established guidelines provide a framework for PEP indications, drug regimens, and patient management.

Conclusions:

  • PEP remains a crucial intervention for preventing HIV infection following exposure.
  • Optimizing the use of PEPSE requires widespread awareness and adherence to established guidelines.
  • Integrating PEP within broader HIV prevention strategies, including treatment as prevention and pre-exposure prophylaxis, is essential for reducing incidence.
