Sexually Transmitted Infections

300
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...

Pulmonary Tuberculosis I

231
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.

Infection

7.8K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Summary

Syphilis screening of U.S.-bound refugees found low infection rates, with 697 cases diagnosed between 2015-2018. Infectious syphilis cases were treated before resettlement, indicating sustained low prevalence for over a decade.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Epidemiology

Background:

  • Syphilis screening is a mandatory part of overseas medical examinations for U.S.-bound refugees.
  • Understanding the prevalence and characteristics of syphilis in this population is crucial for public health.
  • Previous studies have established baseline rates for syphilis among refugees.

Purpose of the Study:

  • To characterize seropositive syphilis cases and treatment among U.S.-bound refugees from 2015 to 2018.
  • To assess trends in syphilis infection rates within the refugee population over time.

Main Methods:

  • Analysis of syphilis screening data from overseas medical examinations for U.S.-bound refugees.
  • Inclusion criteria: refugees aged 15 years and older screened between January 1, 2015, and December 31, 2018.
  • Data collected on seropositive syphilis diagnoses and treatment status.

Main Results:

  • A total of 160,381 refugees were screened, with 697 (434 per 100,000) diagnosed with syphilis.
  • The majority of seropositive cases (63%) were from the Africa region and 58% were male.
  • 53 cases (7.6%) were diagnosed with infectious syphilis, and all were treated prior to resettlement.

Conclusions:

  • Syphilis infection rates among U.S.-bound refugees remained low between 2015-2018, consistent with previous findings.
  • The screening and treatment protocol effectively managed infectious syphilis cases before resettlement.
  • Sustained low prevalence suggests effective public health interventions and screening.
