Computer Scientist
The primary goal of a computer scientist is to solve complex problems using computational techniques and algorithms.
Virologist
someone who studies viruses
Epidemiolgist
study trends & health issues, such as chronic illness and disease outbreaks by gathering info
Bacteria
comes through open holes (mouth, ears, nose wounds), disrupts cella and organ functions, prevented by vaccines or antibiotics, example of disease is tuberculosis
Fungi
spores of fungi, causes tissue damage, diagnosed through the the blood, treated through antifungals, example is athletes foot
helminths
consumption of contaminated foods, causes tissue or organ damage, cures w deworming meds, example is tapeworms
prions
meat, med equipment, causes brain damage, meds can slow but no cure, example is jakob disease
protists
ingestion of feces or raw foods, damage to digestive tract, tissues, or organs, prevented through anti-protozoal meds, example is giardiasis
viruses
contracted through touch, saliva, blood, infects other cells, damages host cells and tissues are destroyed, vaccines prevent, examples are flu influenza
how does a virus infect cells?
Virus infects cells by attaching to host cell, injecting genetic material, replicating inside cell, and releasing new viruses to infect other cells
disease
sickness, either temporary or permanent through transmission or genetically
infections
Infections are caused by harmful microorganisms invading the body, leading to illness or disease. They can be viral, bacterial, fungal, or parasitic.
pathogens
infectetious agents of disease
inherited disease
comes from parents or mutated
infectious disease
spread through other people
host
place that holds the disease
reservoir
place for disease to incubate, ready to spread
susceptible host
vulnerable to disease
chronic
long term condition
congenital
what they are born with
nosocomial
a hospital aquired infection (HAI)
endemic
perpetually present in a community
sporatic
comes and goes in seasons
outbreak
a sudden increase in occurences of disease
epidemic
rapidly spread to a large # of people
pandemic
an epidemic that spread across several countries
First line of defense (innate and nonspecific)
skin and mucus, as well as tears and stomach acid. White blood cells alert and rush to the pathogens, consuming whatever it can. Alerts B cells and T cells
second line (active and specific) steps
T cells arrive, destroying what they can. B cells are alerted and create anti bodies to rapidly and specifically kill the infection
humoral immunity
adaptive immunity from b cells recognizing the pathogen and making an antibody
innate immunity
defensive system what you are born with
adaptive immunity
reacts to new and specific antigens in the body (flu, covid)
passive immunity
when a person already has the antibodies for the disease (vaccines, breast feeding antibodies to baby)
