A Study in a Community in Brazil in Which Cutaneous Larva Migrans Is Endemic

Background. Cutaneous larva migrans (CLM) is a common but neglected parasitic skin disease in impoverished communities of the developing world. Methods. To describe the clinical features and the morbidity associated with CLM, active-case finding was performed during rainy and dry seasons in a rural...

description Background. Cutaneous larva migrans (CLM) is a common but neglected parasitic skin disease in impoverished communities of the developing world. Methods. To describe the clinical features and the morbidity associated with CLM, active-case finding was performed during rainy and dry seasons in a rural community in the state of Alagoas, Northeast Brazil. Results. A total of 62 individuals received a diagnosis for CLM, and among them there were a total of 75 larval tracks. The number of tracks per person ranged from 1 to 3. Children

Results. A total of 62 individuals received a diagnosis for CLM, and among them there were a total of 75 larval tracks. The number of tracks per person ranged from 1 to 3. Children &lt;9 years old were affected significantly more often than other age groups (P &lt; .001). Children had their lesions mainly on the buttocks, genitals, and hands, whereas in older patients, the majority of lesions were located on the feet. Twenty-four percent of the 75 lesions were superinfected. Bacterial superinfection was more common among children. All but 1 patient complained about itching, and 84% of the 62 patients complained about sleep disturbances. Itching was classified as being severe by 61% of patients. Approximately 40% of the 62 patients had attempted to treat their creeping eruption previously. Larvae moved forward 2.7 mm per day. There was a significant correlation between the length of the track and the duration of infestation (ρ = .53; P &lt; .0001). Conclusions. CLM is a common parasitic skin disease in this rural community, with different topographic patterns of lesions in children and adults. CLM is associated with considerable morbidity. The length of the track can be used to estimate the duration of infestation.</description><identifier>ISSN: 1058-4838</identifier><identifier>EISSN: 1537-6591</identifier><identifier>DOI: 10.1086/505221</identifier><identifier>PMID: 16779735</identifier><language>eng</language><publisher>United States: The University of Chicago Press</publisher><subject>Adolescent ; Adult ; Age Factors ; Brazil - epidemiology ; Child ; Child, Preschool ; Dyssomnias - etiology ; Endemic Diseases ; Humans ; Infant ; Infant, Newborn ; Larva Migrans - complications ; Larva Migrans - epidemiology ; Middle Aged ; Pruritus - etiology ; Rural Population ; Time Factors</subject><ispartof>Clinical infectious diseases, 2006-07, Vol.43 (2), p.e13-e18</ispartof><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c347t-11d1aa603f425f32d39f2a6c44fe7cb7399759ea3bfa641683d638d3c10edafd3</citedby><cites>FETCH-LOGICAL-c347t-11d1aa603f425f32d39f2a6c44fe7cb7399759ea3bfa641683d638d3c10edafd3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27901,27902</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/16779735$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Feldmeier, Hermann</creatorcontrib><creatorcontrib>Jackson, Anne</creatorcontrib><creatorcontrib>Heukelbach, Jörg</creatorcontrib><creatorcontrib>Lins Calheiros, Cláudia Maria</creatorcontrib><creatorcontrib>de Lima Soares, Valquíria</creatorcontrib><creatorcontrib>Harms, Gundel</creatorcontrib><title>A Study in a Community in Brazil in Which Cutaneous Larva Migrans Is Endemic</title><title>Clinical infectious diseases</title><addtitle>Clinical Infectious Diseases</addtitle><description>Background.
