Barbara is curious to know more about shingles and the herpes zoster virus that causes it, so she spends many hours researching the virus. During this process,
Barbara learns that many diseases are caused by viruses in the family
. One of particular interest to Barbara is human herpesvirus-1, also known as
herpes simplex virus 1. Surveys of the U.S. population show that about 90% of individuals have been infected with this virus.
What disease does the human herpesvirus-1 cause?
Transmission of HHV-1
HHV-1 is transmitted primarily by oral or respiratory routes, and infection usually occurs during infancy. Frequently, infections are subclinical, but many cases
develop into lesions near the outer margin of the lips.
The difference in canker sores and chancres
Canker sores are painful lesions that appear on the tongue, cheeks, and inner surfaces of the lips, whereas chancres are typically found on the genitals and
are a result of syphilis, a sexually transmitted bacterial infection.
Correct! Cold sores or fever blisters are the painful, short-lived vesicles that form near the outer margins of the lips. It is transmitted via oral and respiratory
routes. In the United States, a large percentage of the population is infected with this virus during infancy, when the virus is passed via respiratory droplets
from family members. (Who can resist kissing a baby?)
