Steps in Outbreak Investigation01:18

Steps in Outbreak Investigation

170
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:

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

167
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Causality in Epidemiology01:21

Causality in Epidemiology

649
Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Classification of Illness01:17

Classification of Illness

7.8K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

15.6K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Infection01:20

Infection

8.5K
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...

Area of Science:

  • Microbiology and Bioinformatics
  • Infectious Diseases and Epidemiology
  • Data Science and Knowledge Engineering

Background:

  • Plague, caused by Yersinia pestis, is a highly lethal infectious disease requiring systematic knowledge integration.
  • Existing plague research literature is vast but lacks a centralized, accessible knowledge base.
  • Efficiently excavating and organizing plague-related data is crucial for advancing research and public health.

Purpose of the Study:

  • To integrate and structure scattered information from extensive plague literature.
  • To facilitate easier data access and knowledge discovery for researchers.

Main Methods:

  • Automated retrieval and integration of 5,388 plague-related abstracts from PubMed.
  • Construction of a plague entity dictionary and ontology using text mining.
  • Development of a multifactor correlation knowledge graph using Neo4j graph database technology.
  • Correlation of scattered knowledge through a knowledge graph with 9,633 nodes and 9,466 relations.

Main Results:

  • A structured and visualized plague knowledge base has been successfully established.
  • The knowledge graph contains diverse entities such as disease, gene, protein, species, symptoms, treatments, and geographic locations.
  • The database effectively manages and provides access to a large volume of structured plague-related data.

Conclusions:

  • The developed plague knowledge base offers an integrated and comprehensive resource for researchers.
  • It significantly aids in understanding plague pathogenesis and exploring potential therapeutic strategies.
  • The knowledge base is pivotal for future research on drug candidate mechanisms and vaccine development, promoting the field of plague research.
