Lice - Description
Lice do not cause dangerous infections. However, they may carry organisms that cause more serious diseases, such as trench fever and typhus. Lice tend to be a problem primarily in overcrowded areas or areas that have inadequate facilities for bathing and laundry. They are often a problem among the homeless or in military or refugee camps. All humans are equally at risk to attack by lice, but elderly people are more prone to develop complications from lice attacks.
