Different types of viruses or bacteria can potential harm an employee, patient or healthcare worker.  Healthcare associated infections (HAI) can contribute to approximately 99,000 people a year being exposed or infected with illness or disease in these environments.  Cleaning and disinfecting can inhabit the growth of these viruses, bacteria or mircoorganisms and break the chain of infection and spread of disease and illness.

The spread of illness or infection can happen by skin (cuts), exposed materials or equipment, it can be airborne or transmitted by animals.  Direct contact is the biggest form of cross contamination.  Disinfecting greatly reduces the risk of exposure.  As an example: Hepatitis C can potentially live up to 6 weeks at room temperature.  Body fluids, tissue and organs can also contain these microorganisms.  

Proper cleaning of surface materials with proper disposal (biohazards) and disinfecting greatly minimizes the risk of exposing healthcare workers, employees and patients of the facility.  Disinfectants can include: synthetic phenols, iodine, bleach/chlorine, quaternary ammonium or alcohol to disinfect surfaces.  It is important to clean and disinfect in a methodical manner: top to bottom, up and down, clockwise around the room.  This helps to make sure all surfaces have been disinfected.  Please check out ijcsa.org,  https://www.ijcsa.org/Janitorial-Service-Directory-Find-A-Janitorial-Service-JanitorialServices to find housekeeping or janitorial services that can fit your need.  They have a directory of services with their locations and contact information.
