The objective of this study was to determine the prevalence of reactive infectious markers at the Centro Hemodador Regional de Loreto from november 2023 to december 2024. A quantitative, descriptive, and retrospective approach was applied. Data from 7,767 donors were analyzed, who underwent screening with infectious markers using the chemiluminescence technique, allowing for a detailed analysis of the prevalence and distribution of these agents in the donor population. Seven mandatory markers in blood banks were evaluated, and for the purposes of the study, sociodemographic variables such as age, sex, marital status, origin, ABO group, and Rh factor were categorized. The overall prevalence of reactive markers was 8.1%. The most frequent marker was anti-HBcAb (4.49%), followed by anti-syphilis (1.47%), anti-HCV (0.61%), anti HTLV-I/II (0.57%), anti-HIV 1-2 (0.37%), HBsAg (0.22%), and anti...

Cassava common mosaic disease (CCMD) can cause root yield losses of approximately 30% (Venturini et al. 2016) in cassava (Manihot esculenta Crantz) and it has already been reported in Brazil, Colombia, Paraguay, and Argentina (Calvert et al. 2012; Di Feo et al. 2015). Most of Peru’s cassava production is in the eastern side of the country (the rainforest region) and is mainly used for direct human consumption. Cultivated area in these regions is approximately 48.1 thousand hectares (MINAGRI 2015). CCMD is caused by Cassava common mosaic virus (CsCMV; Calvert et al. 1996), a mechanically transmitted potexvirus that can be disseminated via infected stem cuttings used for cassava propagation. Given the presence of the disease in neighboring countries, a field survey for virus diseases in cassava was organized during June 2016 in the province of Huaral, in the central coast of Peru, where ...
