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...
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...
Inhibitors of Virion Maturation and Assembly01:19

Inhibitors of Virion Maturation and Assembly

As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...

Transmission-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...
Standard Precaution01:26

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...
Smallpox01:24

Smallpox

Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.

Summary
This summary is machine-generated.

Family physicians can provide timely postexposure prophylaxis (PEP) to prevent human immunodeficiency virus (HIV) infection. Prompt initiation of a four-week, three-drug regimen is crucial for effectiveness, especially after sexual assault.

Area of Science:

  • Family Medicine
  • Infectious Diseases
  • Public Health

Background:

  • Family physicians frequently manage potential human immunodeficiency virus (HIV) exposures.
  • Timely decision-making regarding postexposure prophylaxis (PEP) is critical for preventing HIV transmission.

Purpose of the Study:

  • To outline the indications, optimal timing, and regimens for HIV postexposure prophylaxis (PEP).
  • To guide family physicians in managing various HIV exposure scenarios.

Main Methods:

  • Review of current guidelines and evidence for HIV PEP.
  • Discussion of rapid HIV testing for source identification.
  • Description of two-drug vs. three-drug PEP regimens and their indications.

Main Results:

  • PEP is most effective when initiated within 72 hours and continued for four weeks.
  • Three-drug PEP is recommended for nonoccupational exposures, including sexual assault.
  • Rapid HIV testing can aid point-of-care decisions when source status is unknown.

Conclusions:

  • Family physicians play a key role in administering appropriate HIV PEP.
  • Adherence to timing and regimen guidelines maximizes PEP efficacy.
  • Expert consultation is advised for complex cases, such as pregnant individuals or known HIV-positive sources.
