Question: Who is the "host"? a) COVID b) a sneeze c) the lungs d) the person with covid d
Outbreak vs epidemic Outbreak: occurence of increased disease of what would normally
happen in a community/geographically bound area/season?
Answer:
Question: epidemic: similar to an outbreak but generally more widespread in the population and
often has more serious consequences Endemic infectious disease occuring frequently to a
particular area
Answer:
Question: e.g. Malaria is endemic to parts of Africa Pandemic infectious disease occuring
frequently across the globe Syndemic 2 or more co-existant diseases that results in an
excess burden of disease Prevalence vs incidence
Answer:
Question: Prevalence
Answer:
number of cases at a particular time, new and pre-existing
, Question: Incidence - number of new cases within a certain period of time Mortality rate number of
deaths r/t specific cause within a time period Pathogenicity vs virulence Pathogenicity:
the agent's ability to cause disease in an infected host
Answer:
potential to produce disease (i.e. harm the host)
Question: Virulence: agents ability to produce serious illness
Answer:
disease producing power of an organism T/F Reservoirs are habitats or mediums in which an agent
lives and/or multiplies on living objects only. FALSE
Question: Reservoices can be living or inanimate Which populations bear the greatest burden of
communicable diseases? infants, young children, elderly, and disadvantaged populations

Answer:
Question: - Epidemics mostly limited to developing countries but still primarily a public health
issues
Answer:
Question: Seeing epidemics r/t diarrhea, STIs, leprosy, TB, malaria (and other parasitic diseases)
What are some historical perspectives of 21st century epidemics? r/t globalization =
increased migration and international trade creates conditions for wide geographical
range of disease transmission How can we break the chain of infection in responding to
mode of transmission? HH, sterlization, isolation, engineering controls, PPE
