A louse survey based on samples of cut hair collected from floors of barbershops and beauty parlors was conducted in Belo Horizonte, Minas Gerais State, Brazil, from October 1984 to April 1985, as an alternative way to determine the prevalence of pediculosis capitis in the population. Of 475 samples examined for nits, nymphs, or adults of Pediculus capitis, 140 were infested (29.5%). A total of 58 lice and 3,553 nits were found in 33,632.9 g of hair collected, giving a ratio of 0.10 nit/g. Almost 29% of the nits were viable and capable of being transmitted after hatching. There was significant difference among the infestation rates by socioeconomic levels, and samples from barbershops with male customers were the most infested. Based upon the number of haircuts in each sample, we estimated that 5 or 6% of the population might be infested by this species.

The survey population consisted of primary school children of both sexes ranging in age from 6-25 years. The areas of study were Gambela, Kemise and Debre-Berhan. Only 33.2% of the school children were found to be free from infestation and the rest, 66.8%, harboured body lice ranging in number of 1 to 598. The prevalence in Debre-Berhan (76.2%) was found to be significantly higher (p less than 0.001) than in Gambela (61.4%) and Kemise (62.6%). Similarly the density of lice was higher (P less than 0.001) among Debre-Berhan than among Gambela or Kemise school children. Infestation was commoner among the 11-15 and 16-20 year than the 6-10 and 21-25 year ago groups. There was no difference in the prevalence of lice between the sexes but a higher density was observed among males. The importance of having prior knowledge of the prevalence and abundance of body lice in different areas has been discussed in relation to possible outbreaks of louse-borne diseases.10aadolescent10aadult10aAltitude10aanimals10achild10aEthiopia10ahealth care10ahumans10alice10aLice Infestations/epidemiology10aSchool Health Services10aSocioeconomic Factors1 aTesfayohannes, T. uhttps://phthiraptera.myspecies.info/content/prevalence-body-lice-elementary-school-students-three-ethiopian-towns-different-altitudes01620nas a2200337 4500008004100000245010400041210006900145260000900214300001200223490000700235520059200242653001500834653001200849653002200861653001100883653001000894653001300904653002100917653001100938653003500949653001600984653001401000653003701014100002701051700003001078700003001108700002301138700002701161700002101188856007301209 1998 eng d00aInfestation by Pediculus humanus (Anoplura: Pediculidae) in a metropolitan area of southeast Brazil0 aInfestation by Pediculus humanus Anoplura Pediculidae in a metro c1998 a77 - 810 v323 aAdults, nymphs and nits of the Pediculus humanus were found in a frame-house infesting the clothes and bedding of three inhabitants in a shanty town in S.

Having in view that the precarious living conditions, promiscuity, absence of basic sanitation and negligence of the sanitary authorities in various Brazilian cities, this situation should not be underestimated. This find should be more frequent than an isolated observation.

We found that the prevalence of scalp pediculosis in schools in Abidjan was 18.51%. The girls were more frequently infected than the boys (24.88% for girls and 11.85% for boys). The children most frequently affected were those aged 14 to 15 years (24%) or 6 to 7 years (23. 21%). The children least affected were those aged 12 to 13 years (15. 21%) or 10 to 11 years (16.21%). Socioeconomic conditions, particularly the monthly incomes of the parents, cramped conditions and the collective use of washing facilities and bedding affected the prevalence of scalp pediculosis. Measures to deal with scalp pediculosis in schools should take into account socioeconomic and psychological factors, which are as important as the drug treatment for scalp pediculosis.

The estimated prevalence of louse-infested flocks was 40% (95% confidence interval, 35-46%). Although the prevalence of infestation was higher in western regions (41-50%) compared to the south region of Queensland (31%), the difference was not statistically significant (P > 0.05). Significant (P = 0.02) clustering of infested flocks was detected in the south region where two foci were apparent. We conclude that Queensland sheep flocks have a moderate prevalence of louse infestation, and that clustering of infestation is not strong. The control of lice is an industry-wide issue that needs to be addressed by most wool growers in Queensland.10aanimals10aLice Infestations/epidemiology10aLice/growth & development10aPrevalence10aQueensland10asheep10aSheep Diseases/epidemiology/parasitology10awool1 aWard, M., P.1 aArmstrong, R., T. uhttps://phthiraptera.myspecies.info/content/prevalence-and-clustering-louse-infestation-queensland-sheep-flocks02499nas a2200409 4500008004100000245010200041210006900143260000900212300001400221490000700235520138000242653001501622653001001637653001601647653001801663653001201681653001001693653002101703653002201724653001101746653001401757653001101771653003501782653001601817653001401833653001101847653001501858653002101873653001201894653002101906653001601927653002601943653001001969100001901979700001801998856007302016 2000 eng d00aScabies and head-lice infestations in different environmental conditions of Lower Silesia, Poland0 aScabies and headlice infestations in different environmental con c2000 a170 - 1710 v863 aA comparison of external parasitic infestations among inhabitants of Legnica, Walbrzych, and Wroclaw districts, in the Lower Silesia region of Poland showed a direct relationship between the high incidence of scabies and low standard ecological indices, as well as social economic setting of the communities. In the years 1990-1997, the highest mean incidences of scabies per 100,000 people (80 and 46) were noted, respectively, in the Legnica and Walbrzych districts, compared to only 7.9 in the Wroclaw district. Infestation was correlated with percentages of the population with higher education (4.8; 4.2, 10.1, respectively) and the number of patients per physician (795, 632, 288, respectively), and the percentages of degraded land/and land threatened by degradation (10/37, 5/16, 0.7/10, respectively), forest stands damaged by gases and particulates (99.4, 99.4, 58.8, respectively), and air pollution emission indices in the towns of Legnica and Walbrzych (30 and 21 tons/km2) and Wroclaw (16). Scabies infestation was highest in children and teenagers (0-19) and was gender-associated (in all age groups, women were more often infested than men). A decreasing rate of scabies infestation, especially from the mid-1990s, was noted for both scabies and pediculosis in Walbrzych district; in the 0-19-yr-old inhabitants, it varied from 0.75% in 1994 to 0.41% in 1996.10aadolescent10aadult10aAge Factors10aAir Pollution10aanimals10achild10aChild, Preschool10aComparative Study10ahumans10aincidence10aInfant10aLice Infestations/epidemiology10aMiddle Aged10aPediculus10aPoland10aPrevalence10aRural Population10aScabies10ascalp dermatoses10aSex Factors10aSocioeconomic Factors10aUrban1 aLonc, Elzbieta1 aOkulewicz, A. uhttp://www.phthiraptera.info/sites/phthiraptera.info/files/45018.pdf02347nas a2200361 4500008004100000020001400041245011600055210006900171260002400240300001400264490000700278520124600285653001501531653001001546653001201556653001001568653001101578653001401589653002401603653003501627653001601662653002301678653001401701653001201715653002101727100001601748700001501764700001401779700001801793700001501811700001801826856014101844 2001 eng d a0011-905900aSecular trends in the epidemiology of pediculosis capitis and pubis among Israeli soldiers: a 27-year follow-up0 aSecular trends in the epidemiology of pediculosis capitis and pu aUnited Statesc2001 a637 - 6390 v403 aBACKGROUND: Pediculosis capitis and pubis are not mandatorily reported diseases in most countries. Thus, the reported rates of these diseases in large populations are usually inaccurate and based on estimations. OBJECTIVE: To describe the global epidemiology of pediculosis capitis and pubis in the Israeli Defense Force. METHODS: We analyzed the data obtained from the routine and mandatory reporting of every individual case of pediculosis capitis and pubis to the Army Health Branch Epidemiology Department since 1972 and 1973, respectively. RESULTS: During this period, epidemics of pediculosis capitis and pubis were observed between 1973 and 1985 and 1972 and 1987, with 17.7- and 3.9-fold increases in incidence, respectively. These two epidemics were followed by a sharp decline in morbidity (113.6- and 13.6-fold between 1981 and 1999 and 1984 and 1999, respectively) to the present. CONCLUSIONS: A number of factors could be responsible for the observed decline in morbidity, e.g. socioeconomic, pharmacologic, environmental, or prevention policy modifications. The rates of pediculosis capitis and pubis have continuously declined since the last epidemic of 1972-1987, indicating the influence of these and possibly other factors.10aadolescent10aadult10aanimals10agroin10ahumans10aincidence10aIsrael/epidemiology10aLice Infestations/epidemiology10aMiddle Aged10aMilitary Personnel10aPediculus10aPthirus10ascalp dermatoses1 aMimouni, D.1 aGrotto, I.1 aHaviv, J.1 aGdalevich, M.1 aHuerta, M.1 aShpilberg, O. uhttps://phthiraptera.myspecies.info/content/secular-trends-epidemiology-pediculosis-capitis-and-pubis-among-israeli-soldiers-27-year-fol01865nas a2200337 4500008004100000020001400041245013600055210006900191260000900260300001400269490000700283520087700290653001501167653001201182653001101194653001001205653002101215653001101236653001101247653003501258653001401293653001501307653002101322653002101343653002101364653002601385653001001411100001901421700001901440856006801459 2002 eng d a0074-027600aEpidemiological aspects of head lice in children attending day care centres, urban and rural schools in Uberlândia, central Brazil0 aEpidemiological aspects of head lice in children attending day c c2002 a189 - 1920 v973 aFrom November 1996 to March 2000, a total of 884 children between 0 and 15 years, from 11 institutions including day care centres, public urban and public rural schools in Uberlandia, State of Minas Gerais, central Brazil, were examined for head louse infestation. Children's sex, race, age and some hairs characteristics were shown to be associated to parasite infestation. A prevalence rate of 35% was found and the highest rates were observed in black, female children, with long, dark, wavy hairs. Hairs density and thickness did not seem to influence significantly the distribution of this pediculosis in Uberlandia's schoolchildren. Differences observed between the prevalence rates of head lice in children from the urban institutions suggest there is a greater epidemiological heterogeneity in this group when compared to the rural schoolchildren.

METHODS: We analysed the data based on routine and mandatory reporting of every case of Pediculosis capitis and Phthirus pubis to the Army Health Branch Epidemiology Department, Israel, over the last two decades. RESULTS: The average 20-year incidence of Pediculosis capitis shows a significant rise during the warmer months (R2 = 0.692, P < 0.05) with a parallel significant decrease in the cooler months (R2 = 0.893, P < 0.05). The results for Phthirus pubis show a significantly higher person-time incidence in the winter (P < 0.001). Sensitivity analysis to investigate possible sources of heterogeneity during this time indicated that no single year was an important source of heterogeneity. CONCLUSIONS: Pediculosis capitis is more frequent in the warmer months, whereas Phthirus pubis is more dominant in the cooler months.10aadult10aanimals10aFollow-Up Studies10agroin10ahumans10aincidence10aIsrael/epidemiology10aLice Infestations/epidemiology10aLinear Models10aMiddle Aged10aMilitary Personnel10aPediculus10apopulations10aPthirus10ascalp dermatoses10aSeasons1 aMimouni, D.1 aAnkol, O., E.1 aGdalevich, M.1 aGrotto, I.1 aDavidovitch, N.1 aZangvil, E. uhttps://phthiraptera.myspecies.info/content/seasonality-trends-pediculosis-capitis-and-phthirus-pubis-young-adult-population-follow-20-y02174nas a2200265 4500008004100000020001400041245009600055210006900151260000900220300001400229490000700243520137700250653001201627653001101639653001901650653003501669653001401704653003701718653001101755100001701766700002101783700001501804700002401819856006501843 2003 eng d a0932-011300aPotential role of head lice, Pediculus humanus capitis, as vectors of Rickettsia prowazekii0 aPotential role of head lice Pediculus humanus capitis as vectors c2003 a209 - 2110 v903 aSince the pioneering work of Charles Nicolle in 1909 [see Gross (1996) Proc Natl Acad Sci USA 93:10539-10540] most medical officers and scientists have assumed that body lice are the sole vectors of Rickettsia prowazekii, the aetiological agent of louse-borne epidemic typhus (LBET). Here we review the evidence for the axiom that head lice are not involved in epidemics of LBET. Laboratory experiments demonstrate the ability of head lice to transmit R. prowazekii, but evidence for this in the field has not been reported. However, the assumption that head lice do not transmit R. prowazekii has meant that head lice have not been examined for R. prowazekii during epidemics of LBET. The strong association between obvious (high) infestations of body lice and LBET has contributed to this perception, but this association does not preclude head lice as vectors of R. prowazekii. Indeed, where the prevalence and intensity of body louse infections may be high (e.g. during epidemics of LBET), the prevalence and intensity of head louse infestations is generally high as well. This review of the epidemiology of head louse and body louse infestations, and of LBET, indicates that head lice are potential vectors of R. prowazekii in the field. Simple observations in the field would reveal whether or not head lice are natural vectors of this major human pathogen.

Title: Prevalencia de infestación por Pediculus humanus capitis en escolares de despeñaderos (Provincia de Córdoba) / Prevalence of pediculus humanus capitis infestation in schoolchildren at Despeñaderos, Córdoba Province
BACKGROUND: Approximately 80% of Argentine children have pediculosis, making it imperious to detect the defects in the prevention and control actions for this parasitosis. OBJECTIVES: To study the infestation level by P. h. capitis, its temporal variation, and the association between infestation and host characteristics. MATERIALS AND METHODS: A monthly census in children of 6-8 years old from 2 primary schools (state and private) was carried out, recording the parasite stages found, children characteristics (sex, colour and length of hair), and infestation level. Data were analysed by means of contingency tables, difference of proportions, quotient of chances, and rank correlation coefficient. The independence of variables was analysed by c' test. RESULTS: The prevalence and chances of becoming infested were higher at the state school, where also all infestation levels were recorded, which did not occur at the private institute. The frequency of children infested was significantly lower when they had short hair. The correlation among infestation degree and hair length (short-long) was only significant for boys. Pediculosis cases were recorded at the beginning of the school year in both educative institutions, which demonstrated that infestation was acquired not only at school but also at home. CONCLUSIONS: Pediculosis is a social problems and the whole community must participate in preventive and control actions, for which sanitary education is essential, and the myth that the school is the only place of contagion must be eradicated.

Of the 303 children examined, 43 (14.2%) had P. capitis infestation. The overall infestation rate for P. capitis in Akka children (29.3%, 12/41) was significantly higher than that in Han children (11.8%, 31/262; chi2 = 8.161, p = 0.002). The prevalence in Akka (52.2%, 12/23) and Han girls (19.7%, 31/157) was higher than that in Akka (0%) and Han boys (0%), respectively (p < 0.001), and the prevalence was higher in Akka girls than in Han girls (chi2 = 10.978, p = 0.001). The high prevalence of P. capitis infestation among these girls was possibly due to poor environmental hygiene and unavailability of sufficient water.10aadolescent10aanimals10achild10aChina10ahumans10aLice Infestations/epidemiology10aPediculus10aPrevalence10aThailand/epidemiology1 aFan, C., K.1 aLiao, C., W.1 aWu, M., S.1 aHu, N., Y.1 aSu, K., E. uhttps://phthiraptera.myspecies.info/content/prevalence-pediculus-capitis-infestation-among-school-children-chinese-refugees-residing-mou01369nas a2200313 4500008004100000020001400041245006800055210006700123260001800190300001400208490000700222520047300229653001500702653001000717653001200727653001000739653002100749653001300770653001100783653003500794653002300829653001400852653001500866653001200881653003700893100002800930700002400958856007300982 2004 eng d a0269-283X00aInfestation of people with lice in Kathmandu and Pokhara, Nepal0 aInfestation of people with lice in Kathmandu and Pokhara Nepal aEnglandc2004 a212 - 2130 v183 aThe prevalence of infestation with head lice and body lice, Pediculus spp. (Phthiraptera: Pediculidae) and pubic (crab) lice Pthirus pubis (L.)

A total of 95,153 schoolchildren living in urban and rural areas were examined twice yearly by school nurses. The overall rate of head pediculosis differs significantly between rural (1.59%) and urban (0.48%) schools in eastern Poland. Children between 8 and 12 years old were most frequently infested. Pediculosis was observed most frequently in girls both in the urban (63.5%) and rural (75.3%) schools and this was related with hairstyles. The prevalence of pediculosis decreased with increasing life standards, i.e. with high income, accessibility and consumption of water and better health care systems. Our findings showed that prevalence of pediculosis capitis depends on the age and sex of the schoolchildren and their living conditions. Hygienic controls of schoolchildren by nurses are important in the elimination of Pediculus humanus capitis. Our results confirmed pediculosis capitis is still a problem in different environments, particularly with lower life standards and poorer economic conditions of health care.

OBJECTIVES: To assess the prevalence, seasonal variation and morbidity of pediculosis capitis and scabies in poor neighbourhoods in north-east Brazil. METHODS: The study comprised cross-sectional surveys of a representative population of an urban slum (n = 1460) in Fortaleza, the capital of Ceara State (Brazil) and a fishing community 60 km south of the city (n = 605). Study participants were examined for the presence of scabies and pediculosis capitis. In a longitudinal study in the slum, variation of prevalence in different seasons of the year was assessed. RESULTS: Prevalence of pediculosis capitis was 43.4% in the slum and 28.1% in the fishing community. Children aged 10-14 years and females were most frequently affected. Scabies was present in 8.8% of the population in the slum and in 3.8% of the population in the fishing community. There was no consistent pattern of age distribution. Superinfection was common in patients with scabies, and cervical lymphadenopathy in patients with pediculosis capitis. Multivariate analysis showed that age < or = 15 years, being of female sex and living in the urban slum were independent factors contributing to the simultaneous coinfestation with pediculosis capitis and scabies. The longitudinal data from the urban slum showed a characteristic seasonal variation of pediculosis capitis, but no fluctuation of scabies. CONCLUSIONS: Pediculosis capitis and scabies are hyperendemic in the study areas and are associated with considerable morbidity. There is an urgent need to develop control measures for these parasitic skin diseases in resource-poor communities. This is the first community-based study describing in detail the epidemiology and morbidity of scabies and head lice infestation in Brazil.
