Germs like viruses and bacteria pose health risks on surfaces called fomites. Understanding microbes, surfaces, and disinfectants is key to effective sanitization and preventing pathogen spread.
Area of Science:
- Microbiology
- Environmental Health
- Infectious Diseases
Background:
- Exposure to germs in built environments is linked to human health.
- The COVID-19 pandemic highlighted the need for robust biosafety and hygiene.
- Contaminated surfaces (fomites) act as reservoirs for pathogens, facilitating disease transmission.
Purpose of the Study:
- To review common microorganisms and their associated risks.
- To outline primary classes of antimicrobial agents for surface disinfection.
- To guide the selection of appropriate sanitization strategies for fomites.
Main Methods:
- Literature review of microorganisms, fomites, and antimicrobial agents.
- Analysis of pathogen survival on surfaces.
- Categorization of antimicrobial properties and applications.
Main Results:
- Microorganisms can persist on fomites for extended periods.
- Different surfaces harbor varying microbial risks.
- Antimicrobial agents differ in efficacy against specific pathogens and surfaces.
Conclusions:
- Knowledge of organism, surface, and antimicrobial agent is crucial for effective disinfection.
- Appropriate sanitization practices are essential for preventing pathogen exposure.
- This review provides a foundation for selecting optimal fomite decontamination methods.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
