Head lice are an irritating ailment that has caused numerous people to suffer from severe itching. The infection is spread through head-to-head contact. There are several causes of lice infestation, including poor personal hygiene, poor sanitation, overcrowding, and damp conditions. Refugees and homeless populations are particularly vulnerable to head lice.
The infection can cause itching and redness, but in some cases it may even lead to secondary infections, including Staphylococcus aureus or streptococci. While it is important to treat the lice quickly and thoroughly, the problem may persist for weeks or even months. Lice can also cause anemia if the infestation is severe.
There are several treatments for head lice, but none are 100% effective. The CDC recommends that people with a history of head lice visit their health care provider if they have ever had them. They can prescribe highly effective prescription treatments. These treatments are designed to be applied directly to the scalp.
Head lice are contagious and can infect adults as well as children. The best way to avoid catching head lice is to avoid contact with children unless you have close contact with them.
