Many germs and virus are found on the surfaces in your workplace and home. It is important to keep all your work surfaces clean, especially during a pandemic or emerging disease event. Work surfaces that should be cleaned and disinfected regularly include telephones, computer equipment, and other frequently touched surfaces. Be sure that any cleaner you use is safe to use and will not damage office equipment. Use only
disinfectants registered by the U.S. Environmental Protection Agency (EPA), and follow all directions and safety precautions indicated on the label. Influenza virus can survive on surfaces and still infect a person for up to 2-8 hours after being deposited on the surface. Most viruses are destroyed by heat (167-212°F). Several chemical germicides, including chlorine, hydrogen peroxide, detergents (soap), iodine-based antiseptics, and alcohols are effective against human viruses if used in proper concentration for a sufficient length of time. Germs and viruses spread when someone touches something that is contaminated and then touches his or her eyes,
nose, or mouth. Droplets from a cough or sneeze of an infected person move through the air and carry viruses with them. A person can become infected by touching a surface where these droplets land before touching their eyes, mouth, or nose. Frequent hand washing prevents virus transmission from infected surfaces.

Order of ModulesThis course is designed to increase your infection control knowledge in long-term care environments. Information from this CBT can be directly applied to your daily activities as a nurse aide. This course has five modules. You must save or print the certificate at the end of each module. Keep these certificates as proof of completion.
There is no way to create a lost certificate of completion without taking or retaking the course. If you do not keep a copy for your records, you will need to repeat this course. Let's get started!Lesson Objectives

Cleaning vs. Disinfection
Low-level DisinfectionLow-level disinfection refers to the use of an agent that destroys all vegetative bacteria (except tubercle bacilli) and destroys most viruses - including Hepatitis B virus (HBV), and human immunodeficiency virus (HIV). These agents are not effective against bacterial spores. Examples of low-level disinfectants include hospital disinfectants registered with the Environmental Protection Agency (EPA), with a HBV and HIV label claim. Low-level disinfection is generally appropriate for most environmental surfaces. Intermediate-level DisinfectionIntermediate-level disinfection refers to the use of an agent that kills a wider range of pathogens than a low-level disinfectant but does not kill bacterial spores. EPA-registered hospital disinfectants with a tuberculocidal claim are intermediate-level disinfectants. Intermediate-level disinfection should be considered for environmental surfaces that are visibly contaminated with blood. However, a low-level disinfectant with a label claim against HBV and HIV could also be used. Product Selection

It is important that you understand the directions for use of the product that your facility uses. Cleaning and Disinfecting PracticesFollowing the instructions for use included in the product labeling is important to ensure that the pathogens specified on the label will be killed. Here are a few instructions you should make sure not to overlook:
Standardized ProcessIf you clean surfaces in the wrong order or if you don't follow the recommended practices for the use of cleaning equipment, you may spread pathogens in the environment. Therefore, you need to develop a standardized process to ensure that you are cleaning and disinfecting surfaces appropriately. Lapses that can result in the spread of pathogens in the environment include:
Using Cleaning Equipment AppropriatelyYou should ensure that cleaning equipment is used appropriately. Consider the following practices:
Note: Carts are commonly used by staff to transport supplies throughout the facility. However, if they are not regularly cleaned and disinfected, carts can also serve as a source of pathogen transmission. To minimize the role of carts on pathogen transmission, they should not enter resident rooms and should be cleaned and disinfected at least daily. Cleaning Resident RoomsMultiple studies have demonstrated that patients admitted to a room in which the prior occupant was infected or colonized with a pathogen were more likely to acquire that pathogen during their hospital stay than patients who were admitted to rooms in which the prior occupant was not infected or colonized. You must consider cleaning and disinfection frequencies of resident rooms both for routine purposes and during terminal cleaning. Routine cleaning and disinfection for resident rooms:
Terminal cleaning of a room is performed when a resident has been discharged or transferred and the room is being prepared for another resident.
Cleaning Resident-Care EquipmentFor non-critical equipment, such as blood pressure cuffs or blood glucose monitoring devices, your facility should use either dedicated, disposable items or clean and disinfect equipment with an EPA-registered disinfectant prior to using them with another resident. Laundry
LaundryMuch of the disease transmission from contaminated laundry is due to handling soiled fabrics inappropriately. Handle soiled laundry as little as possible, and never shake/agitate the dirty laundry. Don't "hug" the soiled items - Always carry soiled laundry away from your body. In addition, always wear gloves and follow standard precautions. This includes washing your hands both after handling soiled linen and before handling clean linen. Bacteria ( Salmonella, Bacillus cereus ), viruses (hepatitis B virus [HBV]) and ectoparasites (scabies) presumably have been transmitted from contaminated textiles and fabrics to workers via:
Laundry
The Laundry Process: CollectionThe laundry process starts with the removal of used or contaminated textiles, fabrics, and/or clothing from the areas where such contamination occurred. Contaminated linens and fabrics are placed into bags at the site of collection. These bags are then securely tied or otherwise closed to prevent leakage. A single bag is usually sufficient for containing laundry, but leak-resistant containment is needed if the laundry is wet and capable of soaking through a cloth bag. If the outside of the collection bag is wet or visibly dirty, double bag the laundry. Bags containing contaminated laundry must be clearly identified with labels, color-coding, or other methods so that health-care workers handle these items safely, regardless of whether the laundry is transported within the facility or destined for transport to an off-site laundry service. Personal clothing that is not soiled with body wastes may be stored in a closed container in the resident's closet. The clothing must be collected and cleaned at least weekly. The Laundry Process: Storage and Transport
The Laundry Process: Sorting and Washing
Linen must be washed, dried, stored, and transported in a manner which will produce hygienically clean linen. The washing process must have a mechanism for soil removal and bacteria kill. Normal laundry cycles should be used according to the washer and detergent manufacturer's recommendations. Cleaned wet textiles, fabrics, and clothing are then dried, pressed as needed, and prepared (e.g., folded and packaged) for distribution back to the facility. Policies & ProceduresYou are responsible for knowing the recommended practices for cleaning and disinfecting laid out by your facility's Infection Prevention Control (IPC) program. Your knowledge of the cleaning and disinfection policies and procedures should include:
