Insights

Hepatitis C virus (HCV) remains infectious for days in body fluids like tears and saliva. Hydrogen-peroxide contact lens solutions effectively inactivated the virus, suggesting a potential transmission route and prevention method.

Area of Science:

  • Virology
  • Hepatology
  • Infectious Diseases

Background:

  • Hepatitis C virus (HCV) is a significant global health concern.
  • Transmission routes for HCV remain unidentified in a substantial number of cases.
  • The stability and infectivity of HCV in various human body fluids are not well-characterized.

Purpose of the Study:

  • To investigate the stability and infectivity of Hepatitis C virus (HCV) in different body fluids.
  • To assess the potential risk of HCV transmission through exposure to contaminated body fluids.
  • To evaluate the efficacy of contact lens solutions in inactivating HCV in tear fluid.

Main Methods:

  • Utilized infectious Hepatitis C virus (HCV) cell culture techniques.
  • Analyzed HCV stability in various body fluids including tears, saliva, semen, and cerebrospinal fluid.
  • Simulated HCV contamination in tear fluid and tested the impact of commercial contact lens solutions.

Main Results:

  • Hepatitis C virus (HCV) demonstrated stability and remained infectious for several days in tears, saliva, semen, and cerebrospinal fluid.
  • Hydrogen-peroxide-based contact lens solutions were highly effective in inactivating HCV.
  • Other tested contact lens solutions did not efficiently inactivate HCV.

Conclusions:

  • Hepatitis C virus (HCV) maintains infectivity in various body fluids, posing a potential transmission risk.
  • Direct contact with contaminated body fluids may contribute to HCV transmission.
  • Hydrogen-peroxide solutions show promise for inactivating HCV in specific scenarios, such as contact lens care.

Composition of Body Fluids

Water functions as a solvent accommodating various solutes, which can be categorized under electrolytes and non-electrolytes. Non-electrolytes are usually held together by covalent bonds, restricting them from dissociating in solution, thereby leading to a lack of electrically charged components upon dissolving in water. They are predominantly organic molecules, such as glucose, creatinine, and urea. Electrolytes, on the other hand, are compounds that can break down into ions in water.

Buoyancy and Stability for Submerged and Floating Bodies

In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

Body Water Content and Fluid Compartments

Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions...

Role of Proteins in the Human Body

Proteins are the building block of life. They are also  the most abundant macromolecules with as many diverse roles in the body. They are part of many structural components that provide unique shapes and structures to animal cells, tissues, and organs. In addition, they also act as biological catalysts and carry out several anabolic and catabolic reactions. Notably, some proteins are chemical messengers and regulate many critical processes, such as metabolism, growth, and development. They...

Structural Organization of the Human Body: An Overview

It is convenient to consider the body's structures in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, and organisms.
To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms, and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of...
