a. Vaccination for rotavirus for children younger than the age of 1 year L L L L L L L L L L L



b. Surgical amputation of an extremity with osteosarcoma (bone cancer)

e. Increasing taxes for buying cigarettes L L L L




L ANS: B L




Surgical amputation of an extremity with osteosarcoma (bone cancer) is an example in which
L L L L L L L L L L L L L



when a disease is present the treatment (amputation) is done to reduce the impact of disease by
L L L L L L L L L L L L L L L L L



preventing the tumor from dissemination. Vaccination for rotavirus for children younger than
L L L L L L L L L L L L



the age of 1 year, sexual education program in elementary schools, and increasing taxes for
L L L L L L L L L L L L L L L



buying cigarettes represent examples of primary prevention. Screening for gestational diabetes
L L L L L L L L L L L



after 24 weeks of pregnancy is an example of secondary prevention.

2. This historic character observed that childbed fever mortality more common among women
L L L L L L L L L L L



treated by physicians and medical students compared with women treated by midwives. Based
L L L L L L L L L L L L L



on his observations, he implemented a hand wash policy that resulted in adecrease in mortality.

Name the character that we are talking about.

a. John Snow L



b. Edward Jenner L



c. D.A. Henderson L



d. Leon Gordis L



e. Ignaz Semmelweis L




L ANS: E L




Ignaz Semmelweis identified that medical students and physicians transmitted the disease by
L L L L L L L L L L L



not washing their hands after examining bodies at autopsies and conducting multiple
L L L L L L L L L L L L



examinations in the clinic.

3. Thanks to the contributions of Edward Jenner, the following disease was eradicated later
L L L L L L L L L L L L



by efforts organized by D.A. Henderson:
L L L L L L




a. Cholera
b. Smallpox
c. Chickenpox
d. Polio
e. Zika






, ANS: B L




Smallpox was eradicated in 1980. Edward Jenner vaccinated James Phipps in 1796 against
L L L L L L L L L L L L



smallpox. Almost 200 years later, the World Health Organization (WHO) commissioned
L L L L L L L L L L L



D.A. Henderson to lead the efforts to eradicate the disease.

4. Over the past century, a marked decline in the mortality rates of many infectious diseases
L L L L L L L L L L L L L L



has been observed. Which of the following is the most likely reason for the observed decline
L L L L L L L L L L L L L L L L



in mortality rates from common infectious diseases?
L L L L L L L




a. Development of penicillin L L



b. Development of insulin L L



c. Development of vaccines L L



d. Improvement in social conditions L L L



e. Worse sanitation and unsafe water
L L L L




L ANS: D L




Although medical treatments potentially helped in the decrease of infectious diseases, the
L L L L L L L L L L L



advancement in social conditions played a major role. These improvements include better
L L L L L L L L L L L L



sanitation, safe disposal of waste, better nutrition, and improvement in housing conditions.
