and Designer Babies**The ability to manipulate human genes through technologies like CRISPR
brings with it both excitement and ethical dilemmas. One of the most contentious ethical issues
is the concept of "designer babies," where genetic alterations are made to enhance physical or
intellectual traits. The ethical concerns here involve questions of eugenics, social inequality (if
only the wealthy can access such technologies), and the potential unintended consequences of
genetic modifications on future generations.From a legal standpoint, laws regulating genetic
engineering vary widely by country. In some places, genetic modification of embryos is banned,
while in others, it is allowed under specific conditions. The legal frameworks in place are often
reactive, as the pace of biotechnological advancements often outpaces the development of
appropriate legal standards.#### 10.2 **Stem Cell Research**Stem cell research, particularly
the use of embryonic stem cells, has been a controversial ethical issue for many years. The

Surgical amputation of an extremity with osteosarcoma (bone cancer) is an example in which
when a disease is present the treatment (amputation) is done to reduce the impact of disease
by preventing the tumor from dissemination. Vaccination for rotavirus for children younger
than the age of 1 year, sexual education program in elementary schools, and increasing taxes
for buying cigarettes represent examples of primary prevention. Screening for gestational
diabetes after 24 weeks of pregnancy is an example of secondary prevention.

1. Which term most accurately describes the following definition? “The occurrence in a
community or region of cases of an illness, specific health-related behavior, or other health-
related events clearly in excess of normal expectancy.” [Porta M, ed. A Dictionary of
Epidemiology. New York: Oxford University Press; 2014.]
a. Endemic
b. Epidemic
c. Pandemic
d. Attack rate
e. Incubation period
ANS: B
An epidemic is the occurrence of health-related events in a community or region, in clear
excess of normal expectation. Endemic is not true because it is defined as the constant
occurrence of a disease, disorder, or noxious infectious agent in a geographic area or
population group. Pandemic is not true because it is defined as an epidemic occurring over a
very wide area, crossing international boundaries, and usually affecting a large number of
people. Attack rate is not true because it is defined as number of people at risk in whom a
certain illness develops over total number of people at risk. Incubation period is not true
because it is the interval from receipt of infection to the time of onset of clinical illness (the
onset of recognizable symptoms).
2. What is the most accurate definition of the incubation period (of an infectious disease)?

b. The interval from receipt of infection to the time of onset of clinical illness (the onset of
