Hand hygiene01:23

Hand hygiene

6.1K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Conservation of Small Populations02:04

Conservation of Small Populations

17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Steps in Outbreak Investigation

596
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

What is Population Genetics?01:25

What is Population Genetics?

64.9K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Population Growth00:57

Population Growth

28.7K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Impact of Groups on Groups01:19

Impact of Groups on Groups

258
Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Area of Science:

  • Public Health
  • Infectious Disease Epidemiology
  • School Health Programs

Background:

  • Infectious diseases cause significant absenteeism in school populations.
  • Effective hand hygiene is a primary preventive measure against disease transmission.
  • Evaluating school-based interventions is crucial for optimizing public health strategies.

Purpose of the Study:

  • To systematically review the impact of school-based hand hygiene interventions on infectious disease outcomes.
  • To identify effective components of hand hygiene programs in educational settings.
  • To assess the influence of different intervention types on disease-related absenteeism.

Main Methods:

  • A PROSPERO-registered systematic review following Cochrane methodology.
  • Searches conducted in MEDLINE, Embase, PubMed, and ERIC databases for English-language studies (2014-present).
  • Inclusion of studies with quantifiable hand hygiene-disease relationships in school children, appraised using the CASP checklist.

Main Results:

  • 33 studies were included from 4345 records, featuring interventions like education, handwashing facilities, sanitiser distribution, and integrated Water, Sanitation and Hygiene (WASH) programs.
  • Education-only interventions reduced upper respiratory infection absences by up to 50%.
  • Combined soap/water and sanitiser reduced acute gastroenteritis absences by 36%; integrated WASH programs lowered diarrhoea and respiratory illness absences, with parental involvement enhancing effectiveness.

Conclusions:

  • Multi-component hand hygiene programs combining education, resources, and behavior change are most effective.
  • Intervention success is context-dependent, influenced by infrastructure and delivery methods.
  • While reducing disease and absenteeism, challenges like dermatitis and non-compliance necessitate tailored, inclusive approaches and policy support for sustainable impact.
