General | Latest Info

In the United States, infestation with head lice is most common among preschool - and elementary school - age children and their household members and caretakers. Head lice are not known to transmit disease; however, secondary bacterial infection of skin resulting from scratching can occur with any lice infestation. Getting Head Lice is not related to the cleanliness of a person or his or her environment. Head lice are mainly spread by direct contact with the hair of an infested person. The most common way to get Head Lice is by Head - to - Head contact with person who already has Head Lice. Such contact can be common among children during play at school, home, and elsewhere. Wearing clothing, such as hats, scarves, coats, sports uniforms, or hair ribbons worn by an infested person; Using infested combs, brushes or towels; or Lying on a bed, couch, pillow, carpet, or stuffed animal that has recently been in contact with an infested person. Reliable data on how many people get Head Lice each year in the United States is not available; however, estimate 6 million to 12 million infestations occur each year in the United States among children 3 to 11 years of age. Some studies suggest that girls get Head Lice more often than boys, probably due to more frequent head - to - Head contact. In the United States, infestation with head lice is much less common among African - Americans than among people of other races. Head louse found most frequently in the United States may have claws that are better adapted to grasping the shape and width of some types of hair but not others.

LiceDoctors Can Help!

Lice can crawl from one head to another in secondsfor, instance, when children touch their heads together during play or when they share combs or hat. If friend, relative, or your children's school reports head lice infestation, inspect your child right away. A single female louse can lay up to six tiny, pearl - color eggs, or nits, day. They lay eggs near the base of the hair shaft, especially behind ears or on the back of the neck. A child's first - ever infection might not be detected for month, because that is how long it takes to develop sensitivity to lice saliva, which is what causes itching. During that first month, you might mistake lice infection for dandruff or eczemabut lice infestation doesn't go away after shampooing. If your child has head lice, all household members should be checked and treat, if necessary. You dont need to go crazy with housecleaning because head lice wont survive long if they fall off person and ca feed. To prevent reinfestation, concentrate on cleaning things that your childs head has come into direct contact with in the past few days. Wash or dry clothing and bed linens at temperatures above 130 F. This will kill stray lice and nits. Seal clothing or other items that are not washable in a plastic bag for two weeks, or put them in a dryer. Soak combs and brushes in very hot water for 5 to 10 minutes. Remind your children not to share combs, hair ornaments, or hats, and ask them to stuff their jackets into their backpacks at school, rather than hang them on communal hook.

What Are Lice?

Lice are tiny parasites that live on human beings and feed on blood. They seldom cause serious medical problems, but they are both annoying and contagious. There are three types of lice that can live on people. Head lice are about the size of sesame seed or 2. 1 to 3. 3 millimeters long when adults. Their eggs, called nits, are barely visible whitish or yellow ovals that attach to hair shafts. Having Head Lice does relate to a degree of personal hygiene. Head lice are contagious, especially among schoolchildren. They afflict an estimated 6 million to 12 million children in the United States each year. More girls get Head Lice - likely because girls have more physical contact with one another and share more personal articles that can transmit Head Lice. Head lice are rare among African - Americans, possibly because shafts of their hair have shape that lice cannot grasp easily. Pubic Lice are yellow - gray parasites found in the pubic region and transmitted by sexual contact. There is only 1. 1 to 1. 8 mm long and are also called crab lice, or crabs, because of their shape and crab - like claw - like front legs with which they cling to hair. Eggs can barely be see; these tiny white particles attach so firmly to hair shafts that they are not removed by normal washing. Sometimes pubic lice may be found in other areas of the body containing coarse hair, such as armpits or chest. Body Lice are nearly identical in appearance to head lice but may be more difficult to find. Adults grow to 2. 3 to 3. 6 mm long. When not feeding, they tend to hide in seams of clothing and folds of bedding. If lice is not treat, person can develop complications such as skin sores or bacterial infection of the affected area. Body Lice can also spread blood infections. Lice are found all over the world, wherever people gather in close proximity, such as in schools.

Introduction

Humans are infested by two genera of lice: Pthirus and Pediculus. The Pediculus genus has been studied for decades and is classified based on its ecology, shape and color -. Two ecological forms of Pediculus lice may be distinguish: head lice and body lice. The head louse, Pediculus humanus capitis, lives and lay its eggs in hair whereas body louse, Pediculus humanus humanus, lives and lay its eggs in clothing. Differences in shape between head and body lice have also been describe, but these criteria have not been shown to be relevant enough to divide two into distinct species. Also, louse coloration was described at the beginning of the 20th century, and it was noted that lice have different colors depending on their geographic region and color of their host's skin,. A series of gradations between black head or body louse of West Africa and light dirty grey head or body louse of Europe was describe,. Later, researchers began performing genetic studies on lice -. First, study based on 18S ribosomal RNA gene reported that head and body lice were not phylogenetically distinct. In fact, two phylogenetic groups were describe: Sub - Saharan African lice and other lice that are distributed elsewhere worldwide. Each of these groups contains two distinct subgroups: head and body lice. The divergence of human head and body lice is considered to be a recent event occurring within each of the geographical groups. The second phylogenetic study was based on mitochondrial genes,. This allowed description of three phylogenetically different clades of lice: most common worldwide clade, which comprises both head and body lice, head lice only clade, found in America, Europe and Australia, and another head lice only clade, which was first found in Nepal and Ethiopia but was also recently found in Senegal. Finally, another phylogenetic study of Clade lice based on intergenic spacers reports two clusters of lice: Non - African lice and African lice. Since then, there have been no studies aiming to correlate phenotype and genotype in human lice. Therefore, we want to examine both aspects to determine whether there is any correlation between color, geographical source, ecotype and phylogeny of lice. For this approach, we use Clade lice collected in Senegal, Burundi, Rwanda and Ethiopia. They were photographed and then genotyped with the MST method. To complete phylogenetic analysis of our data, we also used previously genotyped Clade lice from African and Non - African regions.

Lice-Related Challenges

The existence of body lice appears to be positively correlated with male gender, African - American ethnicity and sleeping outdoors among homeless people in San Francisco, according to recent findings. Moreover, testing of lice pools from this population found that 15. 9% of those with body lice were infected with Bartonella quintana, bacterium responsible for trench fever. In the study, California Department of Public Health Vector - Borne Disease Section administered lice - related medical services as part of San Franciscos Project Homeless Connect on nine dates in 2008 - 2010 and 2012. Researchers used a 15 - question survey pertaining to lice transmission for all willing homeless adults who seek these services. Questionnaires address sleeping quarters, frequency of sharing or trading clothing, and previous lice exposure. Lice - related services include examination of ectoparasites of individuals ' hair, body and clothing. Those with lice on their clothing or on the body below the neck are suspected to be infested with body lice. They were given a shower and clean clothing to remove the source of lice. They also provided with educational materials on prevention and control of body lice. They were then escorted to a licensed medical provider for medical evaluation. Lice discovered on head or hair, accompanied by nits, were considered evidence of head lice infestation. Individuals with head lice or more than 20 nits within a quarter inch of the scalp were given a kit consisting of 1% permethrin lotion and nit - removing comb, and were instructed on its use. Free haircuts were also offered to those with severe infestations or mat hair. After collecting between one and 20 lice of each species from the body or head of each patient, researchers place specimens into tubes with 70% ethanol and label them by identifying number and species. One pool of each louse species per participant was sent for DNA extraction, sequencing and PCR testing to CDCs at Bartonella Laboratory in Fort Collins, Colo. B. Quintana, louse - Borne Disease consisting of severe frontal headache, dizziness, conjunctival congestion, shin pain, lymphadenopathy and fever, lasting from 4 to 8 days. Of 203 individuals who received lice examinations and completed questionnaires, 30% were found to have body lice, 4. 9% had head lice, and 3% were confirmed as having body and head lice. Testing of lice pools reveal presence of B. Quintana in 15. 9% of 63 body lice pools, and in 37. 5% of 16 head lice pools. The presence of body lice was correlated with the following variables: male gender, African - American race and sleeping outdoors. According to researchers, these findings suggest that the homeless population in San Francisco has a relatively high rate of lice, and also may be at risk for bartonellosis. Our findings suggest that focusing prevention information, such as promoting use of clean sleeping bags or explaining how to use clean bedding, to those who sleep outside, may be of additional benefit for decreasing lice infestations, and this possibility warrants further investigation, researchers write.
