まとめ

航空機での麻疹の感染は,特にワクチン接種されていない個人に危険性があります. 定期的な予防接種は,暴露後の予防がしばしば不足しているため,航空旅行中の麻疹の発生に対する最善の防御です.

科学分野:

公衆衛生
流行病学
感染症

背景:

機内での麻疹の感染は文書化されている問題です
接触調査は,飛行中の麻疹の暴露後に一般的です.
感染リスクと対応戦略に関する証拠を更新する必要がある.

研究の目的:

商用航空旅行中の麻疹の感染リスクに関する証拠をレビューし,更新する.
飛行中の麻疹の暴露事件に対する公衆衛生の対応を図る.

主な方法:

麻疹と航空旅行に関する記事とプレプリント (2004-2023) を8つのデータベースで検索しました.
商用便での麻疹被曝事件に関する主要なデータを含む研究.
飛行特性,接触調査,結果に関する抽出データ;バイアスのリスクの評価.

主要な成果:

19件の論文が調査基準を満たし,182件以上の飛行に関する調査を記述した.
二次性麻疹の70例は144例のインデックス症例と関連していた.
既知のワクチン接種状態の二次症例の73%は未接種であった.

結論:

航空機での麻疹の感染は既知のリスクであり,ワクチン接種を受けていない人や,インデックスケースのすぐ近くに座っている人に感染します.
暴露後の予防には障壁があり,定期的な予防接種が重要です.
接触調査の有効性に関する確固たる分析は,研究設計によってしばしば制限されます.

Transmission-based Precautions II: Airborne and Protective Environment

1.5K

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Pulmonary Tuberculosis I

321

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.
Mode of...

Asthma-I: Introduction

2.8K

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Infection

8.7K

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...
