公衆衛生は公衆衛生である.
エピデミオロジーエピデミオロジー

背景:

インフルエンザウイルスは世界中に広がり,公衆衛生に重大なリスクをもたらします.
汚染された表面 (フォミット) 経由による間接的な感染は,重要な経路です.
手とフォミット間のウイルス伝播に影響を与える要因の理解は限られている.

研究の目的:

インフルエンザAウイルスのゲノム性RNAの移転を,手と脚の間に量化するために.
表面材料,接触方向,力,環境が転送速度に与える影響を評価する.
曝露評価と衛生戦略の改善のためのデータを提供する.

主な方法:

逆転写定量PCR (RT-qPCR) を利用して,ウイルスのRNA転送を測定しました.
人工皮膚で74回の移植実験 (個別イベント444) を実施しました.
表面材料,接触方向,力,環境条件の影響を分析した.

主要な成果:

表面材料の間でRNA転送速度の有意な差異が観察されました (P <0.001).
接触方向がウイルスのRNA伝達に著しく影響した (P<0.001).
接触力 (P = 0.313) と環境条件 (P = 0.564) は大きな影響を示さなかった.

結論:

表面の材料と向きは,インフルエンザウイルスの伝播を決定する重要な決定因子です.
接触力や環境要因は,ハンド・フォミトの伝染にほとんど影響しない.
調査結果は,インフルエンザの効果的な予防のために,手洗浄と手洗浄の戦略を策定することを支持しています.

Viral Recombination

25.4K

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Transmission-based Precautions II: Airborne and Protective Environment

2.0K

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...

Infection

12.9K

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...

Hand hygiene

6.2K

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.
