ICE -Exam Infection Control Questions
All Solved.
Modes of disease transmission - Answer airborne, direct contact, indirect contact, ingestion,
blood borne, parental, fecal-oral, vector, vertical, transfusions, and transplants
Airborne transmission - Answer droplet infection, aerosols, mists, spatter
inhaled into susceptible host's respiratory system (some are carried long distances)
Direct contact transmission - Answer touching an infected individual
ex: herpes, hepatitis, HIV, TB
Indirect contact transmission - Answer pathogenic organisms left on inanimate objects
wash hands frequently to help prevent this
Ingestion - Answer eating food, drinking beverages, or taking medications that are
contaminated
Bloodborne transmission - Answer infected blood enters a susceptible host through
exposure to blood or body fluids
can be direct or indirect
intact vs non intact skin
ex: HBV, HCV, HIV
Parental transmission - Answer through skin with cuts punctures
blood borne pathogens can occur through needle stick injuries, human bites, cuts, abrasions, or
any break in the skin
Fecal-oral transmission - Answer many pathogens are present in fecal matter
hand washing is critical if not pathogens may be transferred by directly touching another person
or indirect contact with an inanimate object
ex: hep A
ex movie theater seats, swimming pools, food poisoning
vector transmission - Answer ticks, fleas, mosquitos, insects, bites, and stings
tick: lyme disease
, flea: plague
mosquito: malaria, west nile fever
Vertical transmission - Answer mother to child
Transfusions - Answer ie blood, serum, plasma
Transplants - Answer most kinds
Immunity means... - Answer allows the body to resist disease and prevent foreign bodies
from causing infection
Naturally acquired immunity - Answer obtained naturally through having the disease
Active natural immunity - Answer person has the disease and formed antibodies and
memory cells
Passive natural immunity - Answer receive maternal antibodies through placenta or breast
milk
Artificially acquired immunity - Answer immunization or vaccine
Active artificial immunity - Answer vaccine containing weakened disease-causing organisms
or genetically engineer organisms-body forms antibodies
Passive artificial immunity - Answer receive antiserum with antibodies from another host -
replacement therapy for patients with primary immune deficiencies
Viral diseases are transmitted by - Answer Direct contact
Insects
Blood transfusions
Contaminated food or water
Inhalation of droplets expelled by coughing or sneezing
Most common types of hepatitis? - Answer A, B, C
