NR 503 Epi Midterm Final (Student Consult)
Which of the following is a condition which may occur during the incubation period?
Transmission of infection
The incubation period is defined as the interval from receipt of infection to the time of onset of
clinical illness. Accordingly, individuals may transmit infectious agents during the incubation
period as they show no signs of disease that would enable the isolation of sick individuals by
quarantine.
Chicken pox is a highly communicable disease. It may be transmitted by direct contact
with a person infected with the varicella-zoster virus (VZV). The typical incubation time is
between 10 to 20 days. A boy started school 2 weeks after showing symptoms of chicken pox
including mild fever, skin rash, and fluid-filled blisters. One month after the boy returned
to school, none of his classmates had been infected by VZV. The main reason was:
Contact was after infectious period
Subclinical infections were not yet detected
Disease was endemic in the class
The disease is spread by contact with an infected individual who can transmit the agent (VZV) to
immunologically naive persons during the incubation period and for several days after onset of
clinical illness. Since the boy started school 14 days after showing signs consistent with chicken
pox, it is most likely that he was no longer infectious.
The ability of a single person to remain free of clinical illness following exposure to an
infectious agent is known as:
