Week 1 Flashcards
prokaryotes
Cells that lack a nucleus
Eukaryotes
Cells that contain a nucleus
Pathogens
Bacteria which cause disease in humans and animals
Archaea
unicellular, prokaryotic organisms
Protist
An informal group of eukaryotes that are not plants, animals or fungi
phylogenies
Evolutionary relationships
Eliminate
Reduction of disease to zero cases in a defined geographical area
eradicate
Complete and permanent worldwide reduction of a disease to zero new cases
Endemic
infection or illness constantly present in a population/area
acute
short term illness, like a cold
epidemiology
stud of distribution and transmission of a disease through a population
Septicemia
bacteria multiplying in the blood
fomites
inanimate objects that transmit pathogens
nosocomial
infection acquired in a healthcare setting
pandemic
an epidemic that spreads globally
chronic
long term illness, such as a decades long hep B virus infection
Viremia
viruses in the blood
case fatality rate
proportion (rate) of people who die from an illness compared to ill people
systemic infection
infection that spreads throughout the body
latent
infection that is not causing illness at the moment, but may in the future
reservoir
where a pathogen is typically found in nature
incubation period
time between exposure to a pathogen and onset of signs/symptoms
incidence
number of new cases of disease/health outcome in a given time period/ area (typically expressed as a rate per population.
epidemic
rate of infection or illness that is greater than expected level of disease
