humans.
True
False
Definition 2 of 74
Community A receives its water from several sources. The water source responsible for causing an
outbreak of disease X is unknown. The best evidence to determine which suspected water supply
is responsible would be:
the average temperature of each water source during the outbreak period.
the attack rates for disease X in those who did and did not drink from each water supply.
the number of people who reported drinking water from the sources in the last month.
the total volume of water consumed by the community over the past year.

involvement of a microorganism in an infectious disease.

True
False
Definition 11 of 74
In two communities of similar size and age structure (A and B), there were outbreaks of viral
illnesses (Virus A in community A, and Virus B in community B), both of which were traced back to
a single source. Exposure to these viruses in each community confers permanent immunity. In
community A, 200 susceptible people were exposed to an index case, 150 people were infected
(not including the index case), 75 people became ill, and 40 people died. In community B,
pathogenicity was 40%, infectivity was 90%, and virulence was 60%. Choose the best
response:Which virus was most pathogenic?
True
ice scream
Virulence
