Summary
Hepatitis B virus (HBV) transmission is a significant risk in healthcare settings. This study assessed environmental contamination and decontamination methods for hepatitis B surface antigen (HBsAg).
Area of Science:
- Infectious Diseases
- Hepatology
- Environmental Health
Background:
- Hepatitis B virus (HBV) poses a major health risk in healthcare environments like dialysis centers and dental offices.
- Intramural environments, equipment, and procedures are implicated in HBV transmission.
- Hepatitis B surface antigen (HBsAg) serves as a marker for infectious fluids, including saliva.
Purpose of the Study:
- To evaluate the role of the healthcare environment in hepatitis B transmission.
- To develop and apply methods for detecting HBsAg in environmental samples.
- To assess the efficacy of decontamination strategies for HBsAg.
Main Methods:
- Utilized a swab-rinse technique to collect environmental samples.
- Employed radioimmunoassay (RIA) for sensitive HBsAg detection.
- Quantified HBsAg levels in thermal and chemical inactivation studies.
Main Results:
- Developed assays to detect HBsAg on surfaces and in air.
- Quantified HBsAg inactivation under various conditions.
- Identified environmental contamination as a factor in HBV transmission.
Conclusions:
- Environmental assessment using HBsAg detection is crucial for understanding HBV transmission.
- Effective decontamination and sterilization protocols are essential in healthcare settings.
- Recommendations for disinfection and sterilization procedures are provided to mitigate transmission risks.

01:20Infection
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...

01:22Healthcare Associated Infections II: Preventive Measures
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

01:25Transmission-based Precautions II: Airborne and Protective Environment
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...

01:26Standard Precaution
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

01:25Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
