Aspectos clínicos e epidemiológicos da leishmaniose visceral em menores de 15 anos no estado do Rio Grande do Norte, Brasil Clinical and epidemiological aspects of visceral leishmaniasis in children up to 15 years of age in Rio Grande do Norte state, Brazil

Temporal, spatial and spatiotemporal analysis of the occurrence of visceral leishmaniasis in humans in the City of Birigui, State of São Paulo, from 1999 to 2012

“…The higher incidence observed in girls 0-4 years old compared with boys of the same age group differs from other studies that reported no differences in susceptibility to VLH between the sexes 15,18 . In contrast, Costa 19 reported a higher susceptibility in male children younger than fi ve years of age because of the hormonal characteristics of the sex; these differences have not yet been explained.…”

Epidemiological and environmental aspects of visceral leishmaniasis in children under 15 years of age between 2007 and 2012 in the City of Araguaína, State of Tocantins, Brazil

“…However, other studies have demonstrated a preference of the disease for male subjects 4,5 . This divergence in the proportion of cases by gender may be associated with local and environmental factors, as the different studies were carried out in distinct geographical regions with distinct environmental conditions 4,5 .…”

“…The high prevalence of VL in children 5 years of age and younger can be associated with several socio-economic factors: domestic and peridomestic animal breeding, health status with an emphasis on immune maturity and malnutrition studies, and children's habits that provide greater exposure to vectors 5,9,10 . Visceral leishmaniasis occurs as much in urban zones as in rural areas.…”

“…Reports show the emergence of nearly 3,000 new cases annually, and average mortality rates vary between 8% and 10% 3 . This disease affects people in all age groups; however, it can be observed most noticeably in children 10 years of age or under 4,5 . In this age group, children are more exposed to contact with animals while still presenting nutritional deficits and a premature immunological status 6 , which increases their risk of contracting the disease by 109.77 times when compared with older individuals.…”

Occurrence of Lutzomyia longipalpis andhuman and canine cases of visceral leishmaniasis and evaluation of their expansion in the Northwest region of the State of São Paulo, Brazil

“…This result may be related to the incomplete development of the immune system in the children the comorbidity of HVL with chronic diseases, and the decline of the immune system in the elderly (33) (34) (35) (36) . The higher incidence in males is consistent with the literature (33) (34) (36) (37) .…”
