Summary
Postexposure prophylaxis (PEP) is crucial for preventing HIV transmission. This review examines current PEP strategies, evidence, and future directions, including new antiretroviral drugs and novel approaches to enhance its effectiveness.
Area of Science:
- Infectious Diseases
- Public Health
- Pharmacology
Background:
- Postexposure prophylaxis (PEP) is a key component of multifaceted HIV transmission prevention strategies.
- Increasing availability of PEP for sexual and occupational exposures prompts discussions on its cost-effectiveness and utility.
- Evolving antiretroviral drug options necessitate updated guidance on PEP regimens.
Purpose of the Study:
- To review the evidence supporting current practices in postexposure prophylaxis (PEP) for HIV prevention.
- To discuss the cost-effectiveness, utility, and evolving strategies for PEP prescribing.
- To explore potential future developments in PEP, including novel drug classes and treatment approaches.
Main Methods:
- Comprehensive literature review of studies on HIV transmission biology and PEP efficacy.
- Analysis of current international guidelines for PEP prescribing.
- Evaluation of research on drug-drug interactions, alternative regimens, and cost-effectiveness of PEP.
Main Results:
- Evidence supporting the use of PEP in preventing HIV transmission is summarized.
- Current guidelines, including recommended agents, drug interactions, and alternative regimens, are presented.
- Cost-effectiveness and research on the behavioral effects of PEP are discussed.
Conclusions:
- Current PEP prescribing practices are reinforced by existing evidence.
- Future research is likely to focus on novel antiretroviral drugs, new drug classes, and innovative PEP strategies.
- Optimizing PEP regimens remains a critical area for ongoing research and clinical practice.

01:26Sexually 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...
01:10Retrovirus 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...
01:25Transmission-based Precautions II: Airborne and Protective Environment
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...

01:26Standard 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.

01:23Genital 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...
01:17Transmission-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...
