16
Q

MRSA

A

Highly contagious
Enters through open wounds
Can cause serious staph infection
Resistant to most antibiotics
Initially appears as pimple or boil

17
Q

Mycobacterium

A

Contagious bacteria found in soil or water including tap water treated with chlorine
Avoid having cracked dry skin to prevent pathogens From entering body

18
Q

Viruses

A

Submicroscopic infectious particle
Ex common cold flu chickenpox mumps measles rabies HIV hepatitis
Use host cells
Vaccinations may prevent certain viruses

19
Q

Hepatitis A

A

Transmitted person to person contact or consumption of contaminated food/water
Vaccine preventable

20
Q

Hepatitis B &C

A

Blood borne pathogen; highly infectious disease affecting the liver
Hep B is vaccine preventable; immunization is often recommended for personal service workers

21
Q

Herpes simplex virus 1 & 2

A

(HSV-1 & HSV-2)
most common virus estheticians should be aware of
Can show up as a cold sore or as an STD

22
Q

Human immunodeficiency Virus

A

HIV can lead to AIDS
Attacks and destroys the infection fighting cells of the immune system
Infectious fluids can enter through child birth, cuts, sores, sexual intercourse , sharing needles or syringes

23
Q

HPV

A

Human papilloma virus
Only known cause of cervical cancer
Can lead to genital warts plantar warts and cervical changes
Vaccine preventable

24
Q

Parasitic mites

A

Insects that cause contagious diseases (ex head lice (pediculosis capitis ) and itch mites (scabies)
Highly contagious
Infestations can cause severe skin problems with secondary bacterial infection due to scratching

25
Q

External parasites

A

Obtain nutrients from host

26
Q

Scabies

A

Caused by itch mites burrowing under the skin
Commonly found between fingers and toes
Presents as red rash and blisters
Spreads skin to skin
Rarely transfers via clothing or towels
Medical attention required

27
Q

Head lice

A

Transmitted from person to person via articles coming in contact (towels headbands etc)
Usually found at base of neck or behind ears
Head scratching redness and/or small bite marks
Treated by pediculide shampoo
Cannot live off the body for more than 48 hours

28
Q

Fungi

A

Type of mold and yeast that may produce contagious diseases

29
Q

Ringworm

A

Highly contagious
Appears as red round patches that create circles then scales and pustules
Itchiness
Present anywhere on the body
Feeds off dead skin and can spread via towel or facecloth

30
Q

Mildew

A

Fungus that doesn’t cause human infection but can harm plants or surfaces such as sinks and towel bins

31
Q

Biofilm

A

Type of slime created when bacterial colony and water are present
Easily identifiable as slime build up around drain

32
Q

Six signs of infection

A

Pain
Swelling
Redness
Local fever
Throbbing
Discharge

33
Q

Person to person contact

A

Direct transmission; infected person exchanges pathogens with another person through direct contact Ex: warts pink eye and influenza

34
Q

Indirect transmission

A

Object to person transmission
Airborne transmission
Contaminated objects
Food and drinking water
Animal to person
Insect bites
Ex: ring worm mrsa e. Coli

35
Q

Common means of spreading infection

A

Open sores
Unclean hands
Coughing/sneezing
Shared drinks & towels
Use of implements on infected and non infected areas
Non properly disinfected tables and instruments
Unsanitary work conditions

36
Q

Ways to control spread of infection

A

Personal hygiene
Public awareness
Infection control procedures
Vaccinations

37
Q

Two classes of infection

A

Local (small confined area)
General (whole body, systemic, circulatory system carries bacteria and their toxins to entire body)

38
Q

Asymptomatic carrier

A

Carries disease producing bacteria/virus with now recognizable symptoms of the diseases

39
Q

Standard precautions

A

Practice of using the same infection control procedures with all clients.
Properly disinfect tools implements and equipment
Hand washing
Wear PPE
Must be used with blood bodily fluids secretions and excretions (except sweat) mucus membranes and broken skin
