Sexually Transmitted Infections01:26

Sexually Transmitted Infections

292
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...

Infection01:20

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...

Healthcare Associated Infections II: Preventive Measures

2.6K
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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

4.1K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Skin Diseases and Disorders01:23

Skin Diseases and Disorders

3.7K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Epidemiology

Background:

  • Group A Streptococcus (GAS), or *S. pyogenes*, is a virulent Gram-positive bacterium.
  • GAS causes pharyngitis but can lead to severe invasive diseases (iGAS) like necrotizing fasciitis and toxic shock syndrome.
  • While iGAS has declined in developed nations, recent data suggests a potential, though inconsistent, increase.

Purpose of the Study:

  • To address questions regarding the current situation of invasive GAS infections in Spain.
  • To provide expert insights into the epidemiology and clinical aspects of iGAS disease.
  • To inform healthcare professionals about the evolving landscape of GAS infections.

Main Methods:

  • Expert consensus and review of available data on invasive GAS infections.
  • Analysis of trends and clinical presentations of iGAS in Spain.
  • Collaborative response formulation by a committee of specialists.

Main Results:

  • The study highlights the dual nature of GAS, ranging from benign pharyngitis to life-threatening iGAS.
  • Discussion addresses the historical decline and potential recent resurgence of iGAS, with a focus on Spain.
  • Expert insights clarify the current understanding and challenges in managing iGAS.

Conclusions:

  • Invasive GAS disease remains a significant public health concern despite historical declines.
  • Accurate and consistent data collection is crucial for monitoring iGAS trends.
  • Continued vigilance and expert collaboration are essential for managing and preventing severe GAS infections.
