COMMUNICABLE DISEASES Flashcards
entry/ invasion, growth, and proliferation of microorganism into the body
Infection
Needs vector
infectious
easily transmitted and easily infects others
contagious
presence of infection in the body
Sepsis
absence of infection
asepsis
medical hand washing
clean technique
Medical Asepsis
surgical hand washing
sterile technique
Surgical Asepsis
temporary stay of microorganisms in the body or not permanent inhabitants of the body. Meaning, they stay in the body for hours/ weeks only. eg. Candida albicans.
Transient Flora
any microorganism that can cause infection
pathogen
EASILY TRANSMITTED FROM ONE PERSON TO ANOTHER
CONTAGIOUS
permanent inhabitants of the body
resident flora
bacilli that normally reside in the vagina
Doderlein Bacillus
ability of microorganism to cause disease in the body
pathogenicity
vigor/ strength of microorganism to grow and multiply
Virulence
nosocomial infection
hospital-acquired infection
something is rendered unclean/ unsterile
contamination
somebody who carries the microorganism but does not show signs and symptoms
Carrier
direct/ close association with an infected person
Contact
patients shows signs and symptoms
case
process of destroying microorganisms but not their spores
disinfection
halts/ prevent the speed, growth, and multiplication of the microorganism
bacteriostatic
process of killing microorganism including their spores via autoclave
sterilization

SURGICAL ASEPSIS
PREVENTS BACTERIAL MULTIPLICATION
BACTERIOSTATIC

Stages of infection
- Incubation Period
- Prodromal Period
- Illness Period
- Convalescence Period/ Recovery Period
SPECIFIC S/S DEVELOP AND BECOME EVIDENT
ILLNESS
S/S START TO ABATE OR DECLINE UNTIL THE CLIENT RETURNS TO NORMAL STATE OF HEALTH
CONVALESCENCE
EXTENDS FROM THE ENTRY OF MICROORGANISM TO THE ONSET/BEGINNING OF S/S
INCUBATION
EXTENDS FROM THE ONSET OF NON-SPECIFIC S/S TO THE APPEARANCE OF SPECIFIC S/S
PRODROMAL
CHAIN OF INFECTION
- CAUSATIVE AGENT
- RESERVOIR
- PORTAL OF EXIT
- MODE OF TRANSMISSION
- PORTAL OF ENTRY
- SUSCEPTIBLE HOST
Microorganisms, such as bacteria, viruses, fungi, or parasites, that can cause infectious disease.
ETIOLOGIC AGENT
The SOURCE which infectious agents live, grow, and multiply.
RESERVOIR
The route by which an infectious agent escapes or leaves the reservoir.
PORTAL OF EXIT
The way in which an infectious agent travels to other people and places because they cannot travel on their own.
MODE OF TRANSMISSION
The route by which an infectious agent enters a new host
PORTAL OF ENTRY
person at elevated risk for developing an infection when exposed to an infectious agent due to changes in their immune system defenses
SUSCEPTIBLE HOST
It takes place through skin-to-skin contact, as well as kissing and sexual intercourse
Direct
This involves contact between a person and a contaminated object. This is often a result of unclean hands contaminating an object or environment.
Indirect
It occurs when mucous membrane of the nose, mouth, or conjunctiva are exposed to secretions of an infected person Who is coughing, sneezing, laughing, or talking, usually within a distance of 3 feet.
droplet
This ocours when fine particles are suspended in the air for a long time or when dust particles contain pathogens.
Airborne
TYPES OF IMMUNITY
I. ACTIVE IMMUNITY
A. NATURAL ACTIVE IMMUNITY
B. ARTIFICIAL ACTIVE IMMUNITY
II. PASSIVE IMMUNITY
A. NATURAL PASSIVE IMMUNITY
B. ARTIFICIAL PASSIVE IMMUNITY
antibodies produced by the body
ACTIVE IMMUNITY
antibodies are formed in the presence of active infection in the body; lifelong
NATURAL ACTIVE IMMUNITY
Antigens are administered to stimulate antibody production
ARTIFICIAL PASSIVE IMMUNITY
antibodies are produced by another source
PASSIVE IMMUNITY
transferred from mother to newborn through placenta or colostrum
NATURAL PASSIVE IMMUNITY
immune serum from an animal or human is injected to a person
ARTIFICIAL PASSIVE IMMUNITY
VACCINES AND TOXOIDS
ARTIFICIAL ACTIVE
Lifelong
NATURAL ACTIVE
FIRST LINE OF DEFENSE; THEY KILL AND ENGULF BACTERIA AND FUNGI
NEUTROPHILS
HELPS TO BREAK DOWN BACTERIA
MONOCYTES
CONSISTS OF T CELLS AND B CELLS
LYMPHOCYTES
SERVE AS ALARM WHEN INFECTIOUS AGENT STRIKES; SECRETE CHEMICALS LIKE HISTAMINE THAT PRODUCE ALLERGIC RESPONSE
BASOPHILS
ANTI-INFLAMMATORY EFFECTS; ATTACK AND KILL PARASITES; HELPS BASOPHILS IN ALLERGIC RESPONSE
EOSINOPHILS
Five subclasses of antibodies
- IgM
- IgA
- IgG
- IgE
- IgD
An anti body which is found mainly in the blood and lymph fluid, is the first antibody to be made by the body to fight a new infection.
IgM
An antibody which is found in high concentrations in the mucous membranes, particularly those lining the respiratory passages and gastrointestinal tract, as well as in saliva and tears.
IgA
An antibody which is the most abundant type of antibody, is found in all body fluids and protects against bacterial and viral infections.
IgG
An antibody which is associated mainly with allergic reactions and parasitic infections . It is found in the lungs, skin, and mucous membranes.
IgE
PATTERNS OF DISEASES
- SPORADIC
- ENDEMIC
- EPIDEMIC
- PANDEMIC
irregular occurrence of disease
SPORADIC
occurs only infrequently, or occasionally, from time to time in a few isolated places
SPORADIC
when it is consistently/constantly/continuously present but limited to a particular region.
ENDEMIC
Sudden increase in the number of cases of a disease in a short period of time
EPIDEMIC
unexpected increase in the number of disease cases in a specific geographical area.
EPIDEMIC
Worldwide
PANDEMIC
