Diphtheria
is a highly infectious disease of the respiratory tract that most often affects children. The cause
of the disease is an aerobic bacillus that forms V-shaped arrangements. In the early 1900s,
diphtheria was one of the leading causes of death in infants and children in the United States and
many other countries. In the 1940s, infants and children in the United States were regularly
immunized against this disease. In the late 1980s, only two dozen or so cases of diphtheria were
reported in the United States. A toxoid is now given in 2 or 3 doses, about one month apart, to
infants between the ages of three and four months. A booster injection is given about a year later.
Childhood boosters are also given in most cases.

|
Based on the
statement above, which of the following accounts for the decline in the number of people in the
United States who contracted diphtheria in the 1980s? a. | the widespread use of
penicillin | b. | the highly infectious nature of the disease | c. | widespread
immunization | d. | the V-shaped arrangements of the bacterial
cells | | |
|

|
There is an
increasing percentage of adults who have contracted diphtheria. What is the most likely cause of this
trend? a. | The respiratory tract
of an adult is less developed than that of a child. | b. | The bacteria are more
responsive to antibiotics. | c. | Childhood boosters may not be enough in preventing the disease.
Boosters for adults may also be necessary. | d. | Until the 1940s, diphtheria was one of the leading causes of death
only in infants and children. | | |
