Prevalence, incidence, risk factors and residual risk associated with viral infections among eligible Brazilian blood donors.

Knowledge regarding the profile of eligible blood donors presenting positive results in laboratory screening is essential for reducing transfusion-transmitted human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV). Our study aimed to evaluate the prevalence, incidence, predictor variables and residual risk (RR) of HIV/HBV/HCV in blood bags donated in Minas Gerais, Brazil. This study analysed data retrieved from the records of a large blood bank relating to donations collected at multiple centres within the period 2012-2018, during which 1 991 120 blood bags were screened using immunoassays and nucleic acid tests (NATs).

The association between non-permanence of dogs in households and non-compliance with the principles of responsible animal guardianship: A survey in a medium-sized city in Brazil.

The permanence of a dog in a household is relevant in terms of public health and animal welfare because it implies that the animal is receiving better care and is unlikely to be abandoned. We have performed a survey in a medium-sized city in southeastern Brazil in order to identify predictors associated with the non-permanence of dogs in households as determined one year after the first visit. During the first of two visits to randomly selected domiciles, guardians were asked to complete a structured questionnaire regarding the traits and history of each dog in the household, features of the domicile, characteristics of the guardian and adherence to the principles of responsible companion animal guardianship (RCAG).

Responsible companion animal guardianship is associated with canine visceral leishmaniasis: an analytical cross-sectional survey in an urban area of southeastern Brazil.

Background: Responsible companion animal guardianship (RCAG) comprises a set of concepts involving activities, behavior and care that guardians must provide to ensure the welfare of their animals. When such principles are disregarded, the risk of animals developing zoonotic diseases, such as canine visceral leishmaniasis (CVL), increases. This disease is a public health problem in many urban settings in Brazil because dogs are the main reservoirs of Leishmania and are involved in the transmission of the parasites to humans.
