GENERAL
The common cold is one of the most common infectious diseases among people
of all ages. This will probably be the most frequent complaint that you will encounter as
you perform your duties as a medical specialist. More serious infectious respiratory
diseases may occur if treatment is not given in a timely and professional manner.

causes inflammation of the upper respiratory system.

BACKGROUND INFORMATION
a. The common cold is more prevalent in children than adults.
b. It affects more boys than girls among teenagers and more women among
adults.
c. The common cold occurs more often in colder months in temperate zones,
and more often during rainy seasons in tropical zones.
d. There are over 100 different viruses that may be responsible for the common
cold. This makes the development of an effective vaccine highly unlikely.
e. Neither fatigue nor exposure to drafts increases susceptibility.
