Frequent Symptoms

Lice are wingless insects of the Phthiraptera order, of which there are over 5,000 species. Some species are chewing lice that feed off the skin and debris on their hosts. Those affecting humans tend to be claret-sucking species that rely on blood and other secretions to survive.

Broadly speaking, there are three types of lice infestations (pediculosis) that occur in humans:

• Head lice (Pediculus humanus capitis)
• Torso lice (Pediculus humanus corporis)
• Pubic lice (Pthirus pubis)

While the symptoms of hair, body, and pubic lice are similar, their location and the mode in which they spread differ.

Head Lice

Head lice are most common amongst children ages 3 to 11 and are readily transmitted by close contact in daycare and schools. Within that age grouping alone, up to 12 million infestations occur in the United States each year. When schoolhouse outbreaks occur, the infestation tin easily be spread to family members and others.

Despite what some people think, caput lice infestations are not a sign of poor hygiene.

Caput lice reside close to the scalp but can also be found in the eyelashes and eyebrows. The insects don't jump or wing but rather crawl effectually on the peel using their claw-similar legs. They tend to exist most active at night and they can interfere with slumber.

The signs and symptoms of a caput lice infestation include:

• A tickling awareness on the scalp every bit if something is crawling
• Scalp itchiness, causing frequent caput scratching
• Difficulty sleeping accompanied by daytime irritability
• Sores on the scalp from prolonged scratching

Body Lice

Unlike head lice, body lice are associated with poor hygiene. Infestations are common among the homeless and people living in shelters. People who do not have the opportunity to bathe or alter clothes at to the lowest degree in one case weekly are at greatest take a chance.

Another divergence betwixt head lice and body lice is that body lice are generally plant in the clothes and bedding of affected people. While there may be eggs attached to trunk pilus, the nits are mainly concentrated in the seams of clothes and bedding. Torso lice may exist seen on the skin when they are there to feed.

Signs and symptoms of a body lice infestation include:

• Intense itchiness and scratching, particularly around the waistline, groin, and upper thighs
• Darkening and thickening of the peel due to long-term scratching

• Adults (fully grown lice that are able to reproduce)

Depending on the type of lice a person has, the appearance and location of the nits, nymphs, and adult lice can differ.

Caput Lice

Developed head lice tin oftentimes be seen with the naked eye. Fully grown adults are roughly the size and shape of a sesame seed with six legs and a tannish to grayish-white color. The front two legs have larger claws that aid them crawl effectually.
