What
are Head Lice?
Head Lice (Pediculosis humanus capitis) are a human
parasite that is specific to the scalp and hair. Head Lice are
tiny bugs that feed on human blood. Although they are not body
or pubic lice, recent DNA testing has found that they do belong
to the same species as body lice. Body lice are associated with
disease. Many have thought head lice to be only a nuisance but
with this recent development the potential for disease transmission
should not be underestimated.
How
did I get Head Lice?
Head Lice are spread through direct contact with the head or hair
of an infested individual. It is also possible to become infested
through the sharing of personal items like hair brushes, hats, and
towels. Head Lice can also be picked up from surfaces where an infested
person has recently been such as seating in a movie theater or on
an airplane. Head Lice do not jump or fly. They crawl onto a hair
shaft to access your head.
Can my pet carry Head Lice?
Head lice cannot be "caught" from pets and cannot survive
on pets. They are human parasites and require human blood for survival.
Will Head Lice infest any other hair on the
body?
No, Head Lice are specific to the scalp area because it is the only
part of the body where they can reach their food source, our blood.
The epidermal layer (skin) on the head is the only area thin enough
for the bugs to feed. Head Lice will not infest any other areas
of the body such as beards, arm hair or pubic areas.
Why do girls get it more than boys?
Young girls typically have longer hair, giving the bug more opportunity
to climb onto them. Girls also tend to interact in a more affectionate
manner than boys, often exchanging hugs and chatting in close proximity
which leads to direct hair to hair contact and the transmission
of the bug from one head to another.
