What are the signs and symptoms of head lice infestation?
" Tickling feeling of something moving in the hair.
" Itching, caused by an allergic reaction to the bites.
" Irritability.
" Sores on the head caused by scratching. These sores can sometimes
become infected.
People with headlice will have an itchy scalp and often scratch
their heads. Scratch marks or a rash can be a sign. However, not
all children will complain of itchy heads. Headline can also disturb
sleep.
The itching is due to sensitization to the louse saliva, which
may take up to three months to develop after initial infestation.
Secondary infection (with bacteria) due to scratching may develop
and cause sores that discharge pus.
Finding the headlice is the only way to confirm an infection. The
egg cases may persists after the lice have been killed and do not
necessarily indicate active lice infestation.
Look for headlice around the hairline or at the back of the neck,
behind the ears, and on the crown.
Parents are advised to check their children's hair once a week
for signs of lice.
