Lice

Louse are tiny brown and grey parasites that cause itching and scratching, especially on areas of the Lice body that are covered with hair (typically the scalp, neck, and behind the ears).

 

Lice infestation spreads easily - especially by children.

Types

  • Head lice
  • Body lice
  • Pubic lice

Signs & Symptoms

  • Intense itching of the scalp
  • Small, red bumps on the scalp, neck, and shoulders
  • Bumps may become crusty and ooze
  • Tiny white specks (eggs, or nits) on the bottom of each hair that is hard to get off

Causes

Head lice infect hair on the head. They are easiest to see on the neck and over the ears. Tiny eggs on the hair look like flakes of dandruff. Head lice can survive up to 30 days on a human. Their eggs can live for more than 2 weeks.

Diagnosis

To see head lice, you need to look closely. Use disposable gloves and look at the person's head under a bright lead. Full sun or the brightest lights in your home during daylight hours work well. A magnifying glass can also help.

Treatment

Treatment is recommended if even one egg is found

Lotions and shampoos containing Permethrin are usually effective

Doctor can advice you a prescription for medicine that contains insecticides

 

Self care in louse infestation

The treatment for lice involves self-care steps which can be taken at home to make sure all the nits are removed and that all clothing, bedding, personal items and furniture are decontaminated.

 

Washing clothing and bed linens in very hot water or putting them in airtight bags for 10 days can help kill the lice and their eggs. Hair-care items, like combs and brushes, can either be soaked in hot water or medicated shampoo or thrown away.
