Unit 4: Infection Control

Antibiotics

Powerful medicines that fight bacterial infections. used properly it can save lives. They either kill bacteria or keep them from reproducing.

Antimicrobial

An agent that kills microorganisms or inhibits their growth,

Antiseptic

Antimicrobial substances that are applied to living tissue/skin to reduce the possibility of infection, sepsis, or putrefaction

Asepsis

the state of being free from disease-causing contaminants(such as pathogenic bacteria, viruses, pathogenic fungi, and parasites)

Autoclave

Uses pressure, heat, and steam to clean equipment properly, a strong, heated container used for chemical reactions and other processes, such as sterilization, using high pressures and temperatures

Autoclave tape

Looks like masking tape, has ink that turns black when in high temperature. Indicates if proper temperature was reached, and adhesive tape used in autoclaving to indicate whether a specific temperature has been reached.

Bacteria

Microscopic single-celled organisms that thrive in diverse environments. In humans, can be good-like the kind that lives in our guts and helps digestion or can be bad that makes us sick-like MRSA or pnemonia

Barrier

An object worn to prevent transmission of disease. Gloves, gowns, masks, etc.

Biohazard Containers

Hard, leak proof container for sharp objects and/or infectious meterials

Body Fluids

Tears, saliva, sputum, urine, feces, semen, vaginal secretions, pus

Carrier

Person who carries a pathogen without signs or symptoms

Catheter

Tube inserted through skin or opening, used to add or remove fluid

CDC

Centers for Disease Control.
Federal agency for health, safety, and prevention of disease

Chain of Infection

Made up of six different links: pathogen (infectious agent), reservoir, portal of exit, means of transmission, portal of entry, and the new host.

Cilia

The fine hair-like projections from certain cells such as those in the respiratory tract that sweep in unison and help to sweep away fluids and particles

Communicable Disease

Disease transmitted when a pathogen is spread from person to person

Contagious Disease

Communicable disease that is spread from person to person

Contaminated

Soiled, unclean, infected

Cross-infected

Acquiring an infection from somebody else

Dehydrated

Person does not have enough fluid in the body

Direct Contact

Get pathogens by touching an infected person

Disinfection

Measures used to stop spread of disease

Drainage

Flow of fluids from a wound or cavity

Fungi

Fungal diseases are often caused by fungi that are common in the environment. Most fungi are not dangerous, but some types can be harmful to health

Immunity

Resistance to infection by a pathogen

Incubation Period

From time pathogen enters the body to time it causes infection symptoms

Indirect Period

Touching something that is from a contaminated person

Indirect Spread

Transmission of disease form an object, insect, animal

Infection

The invasion and multiplication of microorganisms such as bacteria, viruses, and pathogens that are not normally present within the body

Infectious Disease

Disease caused by growth of a pathogen

Isolate

Keep someone seperate

Malnutrition

Person not getting proper nutrition

Microorganism

Tiny living thing that is not visible to the human eye

MRSA

Staph infection that is resistant to antibiotics

OSHA

Federal agency that makes rules to protect workers from hazards at work

Parasites

An organism that lives in or on another organism(its host) and benefits by deriving nutrients at the host's expense

Re-infection

Infected for the second time

Reservoir(related to infection control)

Any person, animal, arthropod, plant, soil, or substance (or combination of these) in which an infectious agent normally lives and multiplies, on which it depends primarily for survival, and where it reproduces itself in such manner that it can be transmi

Resistance

Body's ability to prevent infection

Vaccine

Substance made from killed microbes used to give immunity to a disease

Viruses

A virus is a small infectious agent that replicated only inside the living cells of other organisms. It can infect all types of life forms, from animals and plants

Transmission

Transfer of a disease to someone else

Infection Control

Methods used to control and prevent the spread of disease

Pathogens

Harmful microorganisms

Localized

At a specific place, not the whole body

Systemic

In bloodstream, move throughout the body

White Blood Cells

Also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders

Signs of a localized Infection

Redness, swelling, pain, heat, drainage, fever

Signs and Symptoms of a Systemic Infection

Fever, chills, headache, change in vital signs(blood pressure, respiratory rate, etc), nausea, vomiting, diarrhea, Mental confusion

Chain of Infection

1. Have to have a causative agent
2. Reservoir where it is located(a host)?
3. Portal of exit - how does it get out of host?
4. Mode of transmission - how does it get to host?
5. Portal of entry - how does it get into host?
6. The host must be susceptible

Causative Agents

Pathogens can cause disease, Pathogens are found everywhere - on the skin, in the food, air, water. They include: Bacteria, viruses, fungi, parasites
