まとめ
天然の症例死亡率 (CFR) は,人口の感受性および社会的文脈に基づいて著しく変化しました. スウェーデンの小児性天然の流行は,アイスランド (43-55%) のすべての年齢に影響する流行よりも低いCFR (8-10%) を示しました.
科学分野:
- エピデミオロジー エピデミオロジー
- 歴史的人口統計学 歴史的人口統計学
- 公衆衛生は公衆衛生である.
背景:
- 小型天然 (Variola major) は歴史的に公衆衛生に重大な脅威をもたらしてきました.
- 天然の内在的症例死亡率 (CFR) は,しばしば20〜30%と記載されていますが,この数字は重要な文脈的要因を考慮していない可能性があります.
研究 の 目的:
- 天然の症例死亡率 (CFR) の妥当な範囲を推定する.
- 人口の感受性および社会的要因が天花熱CFRに及ぼす影響を調査する.
- 歴史的な人口統計データを組み込むことによって,天然に関するコンセンサスCFRに異議を唱える.
主な方法:
- 18世紀のスウェーデンにおけるの死亡率の分析.
- アイスランドにおける1707-09年の天然の流行による死亡者数に関する調査.
- CFRの推定値の比較は,異なる年齢の感受性および固有性のパターンを有する集団の間で行われました.
主要な成果:
- 小の推定CFRは,子供と成人の両方が感受性のある集団 (例えば,アイスランド) で著しく高かった (43-55%).
- 天然の推定CFRは,この病気が流行し,主に子供に影響する集団 (例えばスウェーデン) でかなり低い (8-10%) であった.
- この研究では,家事や介護の障害などの社会的要因が,疫病の際にCFRの増加の主な決定因子として特定されました.
結論:
- 天然の固有のCFRは固定値ではない可能性があり,社会的および人口学的文脈によって大きく影響を受けます.
- 天然の歴史的および疫学的分析は,CFRを報告する際に,人口の感受性と社会的混乱を考慮すべきである.
- 天然のコンセンサスCFRが20〜30%であることに頼ることは,単純化であり,特定の歴史的集団に対して不正確である可能性があります.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Pulmonary Tuberculosis I
1.0K
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Hazard Rate
457
The hazard rate, also known as the hazard function or failure rate, is a statistical measure used to describe the instantaneous rate at which an event occurs, given that the event has not yet happened. From a probabilistic perspective, it represents the likelihood that a subject will experience the event in a very small time interval, conditional on surviving up to the beginning of that interval. In terms of frequency, the hazard rate can be viewed as the ratio of the number of events to the...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
