Lice are not dangerous and they do not spread disease but they are contagious.
Head lice are tiny wingless parasitic insects that live on human hair & feed on small amounts of blood. They are a very common problem especially for children ages 3 to 12 years of age. Their bites can cause the scalp to itch & the scratching that can lead to infection.
Lice are very contagious & can spread quickly from person to person. They can't fly or jump but can crawl and cling firmly to hair. They are spread thru close contact like sharing clothes, beds & combs and brushes.
Treatment with over the counter products is available but it is very important to follow the directions on the package. If the product is used too often it can cause harm. As always, contact your doctor with any questions you may have.
