Global status of visceral leishmanial infection among blood donors: A systematic review and meta-analysis

Socio‐epidemiological characterisation of blood donors with asymptomatic Leishmania infantum infection from three Brazilian endemic regions and analysis of the transfusional transmission risk of visceral leishmaniasis

“…Some authors consider that molecular tests provide an accurate estimate of the infection rate of asymptomatic individuals and that they are suitable for donor screening in endemic regions of visceral leishmaniasis (Asfaram et al, ). However, by following individuals from an endemic zone for 12 months, Moreno () observed that, although the molecular tests had a better performance, they showed great variability, in which individuals with previously positive tests become negative and vice versa (Moreno, ; Jimenez‐Marco et al, ).…”

Asymptomatic Leishmania infection in blood donors from a major blood bank in Northeastern Brazil: a cross-sectional study

“…In the Mediterranean Basin, Middle East, Central Asia, South America and Central America, VL is a zoonosis caused by Leishmania infantum 5 . Although primarily transmitted by female phlebotomine sand flies 6 , L. infantum may also be transmitted by other routes, including blood transfusion 7 . Cases of transfusiontransmitted leishmaniasis have been reported in several countries such as Belgium, France, Brazil, Sweden and the United Kingdom 7 .…”

Estimation of Leishmania spp. infection in asymptomatic people from Muzaffarpur, Bihar, India by antigen-antibody and skin testing

“…Asymptomatic VL is a concern, considering the risk of transmission in highly endemic areas due to human-to-human transmission 6 , 7 . The seropositivity in blood donors can vary between 0.25to 16% 6 , 7 .…”

“…Asymptomatic VL is a concern, considering the risk of transmission in highly endemic areas due to human-to-human transmission 6 , 7 . The seropositivity in blood donors can vary between 0.25to 16% 6 , 7 . To understand the factors involved in VL transmission and maintenance, particularly related to the prevalence of infected asymptomatic individuals, the aim of this study was to report the sero-epidemiological prevalence in Bihar, India, a highly endemic area of visceral leishmaniasis, using the leishmanin skin test (LST) and the direct agglutination test (DAT).…”
