- COVID-19はネパールに大きな影響を及ぼし,伝播パターンは地理的に影響を受けています.
- これらの空間的動態を理解することは 効果的な公衆衛生戦略に不可欠です
研究 の 目的:
- 2020年1月から2022年12月までのネパールにおけるCOVID-19発生の地区レベルの変動を分析する.
- COVID-19の分布の空間的パターン,ホットスポット,および主要な要因を特定する.
主な方法:
- 実験室で確認されたCOVID-19症例の空間統計とジオ検出器の方法を使用した.
- 地域レベルでの物理的,生物的,社会環境的説明変数を分析した.
主要な成果:
- 大都市 (カトマンズ,ポクラなど) のホットスポットでは,1000人あたりの感染者数は133人に達した.
- 主な要因は,道路の密度 (q=0.59),ICUベッドの分布 (q=0.51),人口密度 (q=0.46) である.

Causality in Epidemiology
822
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...

Steps in Outbreak Investigation
199
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:

Prevalence and Incidence
802
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Single Nucleotide Polymorphisms-SNPs
15.9K
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,...

Pareto Chart
7.0K
A Pareto chart is a bar graph or a combination of both line and bar graphs. The bar lengths represent the individual values or the frequency, while the lines represent the cumulative total values. In this chart, the longest bars are arranged on the left and the shortest bars on the right, which makes it easier to read and interpret the data. It can also be called a Pareto diagram or Pareto analysis.
The Pareto chart is named after the Italian economist Vilfredo Pareto, who described the Pareto...

Principles of Disease Surveillance
180
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...
