Q
Herd Immunity
A
- population immunity
- when a large percentage of the population is vaccinated, the spread of disease is limited because there are fewer people to pass the illness around. this indirectly protects unimmunized individuals.
2
Q
General Prevention Measures
A
- vaccines
- proper handwashing
- insect repellant
- protective devices: ex// masks, gloves
- social distancing
- sanitary practices: ex// showering
3
Q
Nosocomial Infection
A
an infection that can be acquired after admission to a healthcare facility
4
Q
First Line of Defense
A
- non-specific this line of defense is geared at preventing pathogens from breaching our outer layer.
- barriers include: mucus membranes, skin, skin secretions, respiratory mucus and cilia, and digestive system defenses -
- ex// skin, tears, mucus, cilia, stomach acid
5
Q
Second Line of Defense
A
- made up of responses to infection that apply generally to all pathogens
- nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals
- ex// Phagocytic cells ingest and destroy all microbes that pass into body tissues
6
Q
Third Line of Defense
A
- provides immunity against specific pathogens.
- when the non specific physical and chemical barriers can’t destroy the pathogens, the specific immune systems is activated to fight off invading organisms.
7
Q
Antibiotic Resistance
A
- when bacteria are no longer affected by our antibiotics and can survue them.
- can be caused of genetic mutation or overuse and misuse of antibiotics
