Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic01:26

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

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. Common...

Skin Diseases and Disorders

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...
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
Healthcare Associated Infections II: Preventive Measures01:22

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...
Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Summary

Scabies outbreaks in hospitals are a significant concern, often originating from undiagnosed cases in vulnerable patients. Effective control requires prompt diagnosis and strict infection control measures.

Area of Science:

  • Dermatology
  • Infectious Diseases
  • Public Health

Background:

  • Scabies is a widespread parasitic skin disease affecting millions globally.
  • Nosocomial outbreaks pose risks to patients and healthcare workers, causing significant morbidity.
  • Crusted scabies in immunocompromised or elderly patients is a primary source of hospital transmission.

Purpose of the Study:

  • To review the epidemiology and transmission dynamics of scabies in healthcare settings.
  • To identify factors contributing to hospital-acquired scabies and nosocomial epidemics.
  • To outline strategies for outbreak containment and prevention in hospitals.

Main Methods:

  • Review of existing literature on scabies epidemiology and nosocomial outbreaks.
  • Analysis of factors influencing transmission, diagnosis, and control.

Related Experiment Videos

  • Examination of infection control protocols and treatment strategies.

    • Main Results:

    • Delayed diagnosis and poor healthcare worker knowledge facilitate scabies spread.
    • Atypical presentations and long incubation periods complicate early detection.
    • Hospital-acquired scabies leads to considerable economic and workload burdens.

    Conclusions:

    • Strict adherence to infection control measures is crucial for containing scabies outbreaks.
    • Enhanced surveillance, prompt diagnosis, and treatment of contacts are essential.
    • Improving healthcare worker education on scabies is vital for prevention.
