medical terminalogy

vaccines pharmacologic agent capable of producing artificial active immunity.`
virulence an organism relative power and degree of pathogenicity.
severe acute respiratory syndrome ( SARS) a viral outbreak of a respiratory illness first reported in Asia in 2003; spread by close person-to-person contact and characterized by fever and respiratoy symptoms.
mortality number of cases of deaths to a given population.
morbidity number of cases of disease in a specific population.
transmission spread of infectious disease by direct contact, indirect contact, inhalation, or bloodborne contact.
infectious agents pathogen responsible for a specific infectious disease.
epidemiology is the science that studies the history, cause, and patterns of infectious diseases.
infection control methods to eliminate or redice the transmission of infectious microorganisms.
bloodborne pathogen microorganism capable of causing disease found in blood or components of blood.
immunosuppresed referring to a pt. because immune sys is unhealthy because of disease,medication, gentics,ect..also antibodies produced by the cell of the immune system.
microorganisms microscopic living creature capable of transmisson and reproduction in specific circumstances. are found almost every where and cannot be seen by the naked eye.
pathogens microorganisms that can cause infectious disease.
Chain of Infection 1. infectious agent2. reservior3. portal of exit4. means of transmission5. portal of entry6. susceptible host
infectious agents virus, bacteria, fungi, parasites, and rickettsia
Virus virus are pathogens that require a living cell for reproduction.
palliative measures taken to relieve symptoms of disease.
Bacteria are single-celled microorganisms that live in tissue rather than in body cels and are identified by characteristics shapes or morphology (form and structure of an organism)
fungi are microoangism that may be unicelluar (single-celled)
parasites organisms that live in or another orgamism are classified as parasites.
Riskettsia are intracelluar parasites smiliar to a virus, they are larger than virsus and can be seen undre conventional microscope.
excretions waste matter the elimination of waste products from the body
secretions substance produced by the cells of glandular organs from material in the blood
standard Precautions dev in 1996 by the CDC they privide a wider range of protection and are used any time there is contact w/blood,moistbody fluid, mucous membranes, or nonintact skin ther are designed to protect all health care provider,pts, and visitors
Transmission Based Precautions seconf tier of CDC guide lines applies to specific catagories of pts that include air, contact and droplet precautions
Means of Transmission 1. direct contact 3. Bloodborne Transmission 4. ingestion5. inderect contact 6. Vector (a carrier of disease)
Portal of Entry broken skin mucous membrane and systems of the body exposed to external envirorment breathing in airborne microoganisms allows infectious disease to enter the lungs.
growth requirements for microorganisms oxygen, lack of or no oxygen, moisture nutrition, temperature,darkness
Riskerrsiae ticks, lime, fleas, and mites
Reservior second link in chain infection; people, equipment, supplies, water, food animals, insects
Portal of entry fith link in chain infection; broken or non-intact skin, respiratory tract, gastrointestinal tract, mucous membranes, reproductive system
Susceptible Host sixth link in chain of infection; number and specific type of pathogen, duration of exposre, general physical health, psychological health status, occupation or lifestyle envirorment, underlying diseases or condtitions, youth or advanced age
Bodys Natural Barriers physical,chemical,cellular
Inflammatory Response cardinal signs are redness, heat, swelling and pain; dilation of vessels increase blood flow, plasma moves into tissue, white blood cells activated to fight infection, phagocytes destroy pathogens
pathogen disease producing microorganism
Immune-system response recognition of invader,growth of defense, attack against infection, slowdonw of immune response following the death of infectious agent
immunity *naturally acquired active immunity* artificially acquired active immunity* congenital acquired active immunity* artificially acquired passaive immunity
purulent forming or containing puse
barriers to protect an individual form contact wirh blood and other potenitally infected materials. like PPE
PPE personal protective equipement
immune system purpose is to protect against pathogens and abnormal cell growth
Cell-mediated immunity usually involved in attacks and eliminates pathogens
humoral immunity produces antibodies that are capable of killing miccrorganisms and of reconigzing the pathogen in the future.
AIDS is caused by a blood born virus, HIVthe viral infection directly affects the immune response
HIV is responsible for the T cell destruction, t cells are white blood cells that provide immunity
hepatitis B HBV-MOST COMMON VIRUS concered a serious biohazard for health care providers, it is easier to contract, symptoms are loss of appettite, fatigue, nausea, headahce, fever, and juandice this is a chroni disease,
HEPATITITS C HCV-MOST COMMON VIRUS, can become chronic individuals can carry the virus in their blood for the rest of their lives, damages the liver and causes cirrhoisia and liver failure,
medical asepsis is the use of practices such as hand washing general cleaning and disinfecting of contaiminated surfaces
surgical aspsis is to prevent organisms from entering the pts body during an invasive procedure
