Body lice are parasitic insects that live on clothing and bedding used by infested persons. The parasite has three forms: the egg (also called a nit), the nymph, and the adult.

There are 3 types of ticks that often exist in humans, body lice and head lice, pubic lice. Body lice are 2-3 mm. we can find many of them in the cold areas, while in the tropics most are head lice. Body lice are a factor of typhoid disease that occurs only in cold areas. But head lice may be the host of reserves for typhoid organisms and have the potential to transmit them. Body louse is a "weird" flea because of its life on the shirt (in cold areas people wear double clothing more than 2 and long not washed because people rarely sweat), when the cold then he moves into the body of the host, so usually this fleas stay in clothing first layer.

The body lice eggs are placed on the shirt fibers and hatch about 1 week later, immediately forming the nimpa and will mature when close to the host's body. If the clothes are not worn for several days then the lice will die.

In general body louse is not a frightening disease, but this tick bite can cause discomfort, arise small red papules and can develop into the emergence of exudates. Itching occurs and causes the crust to develop into dermatitis and secondary infection. Symptoms occur for days depending on the sensitivity of an attacker.

Intense itching ("pruritus") and rash caused by an allergic reaction to the louse bites are common symptoms of body lice infestation. When body lice infestation has been present for a long time, heavily bitten areas of the skin can become thickened and discolored, particularly around the midsection of the body (waist, groin, upper thighs); this condition is called "vagabond's disease."

The prevention of ticks is to keep the body clean, routine washing clothes, bed sheets and towels and not using clothes and towels simultaneously is the main thing. In those already infected with lice infestation on the body it is necessary to take action to remove the lice. Some of the ways that need to be done is to improve personal hygiene, wash all clothes, bed sheets, towels and other cloths used last week with hot water and then dried by a dryer with hot air. This is because the heat will kill the lices.
