Communicable Diseases Flashcards
These are diseases that can be transmitted from one person to another.
Communicable Diseases
Is caused by pathogens.
Infection
Microorganisms that can cause diseases.
Pathogens
A place where the disease agent can survive, grow, and multiply.
Reservoir
Path for the microorganism to leave/escape from the host.
Exit Route
Path for the infectious agent to enter another host.
Entrance Route
Individuals who CANNOT resist the growth of pathogens.
Susceptible Hosts
What are the two modes of transmission?
Direct contact ( person to person )
Indirect contact ( object to surface )
• Silent stage when the pathogens grow and multiply
• Time interval between the onset of infection and the start of the symptoms
Incubation Stage
• The time when general symptoms begin to manifest which last for about one or two days
Prodromal Stage
• More symptoms are visible
• Period when the disease is at its peak and can be clinically used to diagnose the disease
Acute/Illness Stage
• Starts when the disease symptoms have vanished and the patient is beginning to recover
Recovery Stage
• The quality of being unhealthful and is used to describe how often a disease occurs in a specific area
Morbidity
• The condition of being subject to death and refers to the number of deaths in a population
Mortality
What was the top 1 causes of morbidity in 2015?
Acute Respiratory Infection
What was the top 1 causes of mortality in 2015?
Diseases of the Heart
What are the 3 levels of prevention?
• Primary Prevention
• Secondary Prevention
• Tertiary Prevention
This spares the client the cost, discomfort, and the threat to the quality of life that illness poses or atleast delay the onset of ilness
Primary Prevention
It begins in the period of recovery from an illness.
• Administering appropriate medications
• Moving and positioning and doing passive & active exercise
Tertiary Prevention
• Are single-celled microorganisms and only a hundred are known to be pathogenic
• Grows in hot places, while others thrive in cold, damp places
• Produce toxins
Bacteria
A patient comes in stating he’s been having :
• watery diarrhea
• fever
• abdominal cramps
• nausea or vomiting
• fatigue
• dehydration
• decreased amount of urine
What is your diagnosis?

Transmission : •Unhygienic Practices
•Intake of contaminated food & water
A patient comes in stating they’ve been having :
• fever & headache
• fatigue
• muscle aches

A patient comes in and states that they’ve been having these symptoms :
• persistent cough
• blood when coughing
• chest pain
• fatigue & fever
• weight loss
• night sweat & chills
Bacteria : Mycobacterium Tuberculosis
Diseases Caused : Active Tuberculosis ( Active TB)
Transmission :
• airborne - droplets from cough, sneeze, or spit of an infected person
• smallest of all pathogens
• more than 150 of these can cause diseases
• difficult to treat & drug treatments are very limited
• cannot reproduce on its own
• can exist only within a LIVING host
Viruses
