Zika Virus Infection in Asymptomatic Pregnant Women.

: Zika disease is caused by the Zika virus (ZIKV) and represents a major public health problem because of the complications in newborn babies from mothers who were infected during pregnancy. It is estimated that 80% of infected pregnant women are asymptomatic, which complicates the identification of infected individuals. In this study, we aimed to detect ZIKV in asymptomatic pregnant women and the effects in the newborns were analyzed.

Blood donor notification rate in a blood bank in Veracruz, Mexico.

Blood banks are primarily responsible for providing safe blood, but they also indirectly act to prevent the spread of infectious diseases by notifying blood donors of positive screening results. The notification process differs between countries and notifications rates are generally low. This study sought to analyze the notification rate of healthy and infection-positive donors who donated blood at CETS-Veracruz.

Use of Investigator 24plex GO! To analyse allele frequencies of 21 autosomal STRs in the population of Veracruz state, Mexico.

Background: Mexican population databases for autosomal STRs are scarce, and no previous studies have been performed with the Qiagen Investigator 24plex GO!

Aim: To analyse the frequency of 21 autosomal short tandem repeat (STR) loci and forensic parameters in individuals from Veracruz state, Mexico.

Subjects And Methods: A total of 234 unrelated individuals were analysed with the Investigator 24plex GO! Kit, which includes the following autosomal STRs: TH01, D3S1358, vWA, D21S11, TPOX, D1S1656, D12S391, SE33, D10S1248, D22S1045, D19S433, D8S133879, D2S1338, D2S441, D18S51, FGA, D16S539, CSF1PO, D13S317, D5S818, and D7S820. Allele frequencies, forensic parameters, and relationships with neighbouring Mexican populations were estimated.

Occult hepatitis B infections and anti-HBc prevalence at a resource-limited blood bank in Mexico.

Objectives: To identify blood donors with occult hepatitis B infections (OBIs), determine the prevalence of antibody to hepatitis B core antigen (anti-HBc) positivity and estimate the impact of anti-HBc screening on donor deferral at CETS-Veracruz (Mexico).

Background: Hepatitis B virus infection is a major concern in transfusion medicine. Mexican regulations only mandate screening for hepatitis B surface antigen (HBsAg), and there are no requirements regarding testing for anti-HBc or use of a nucleic acid test (NAT).

Trends in prevalence of HIV and syphilis in a central blood bank of Veracruz, Mexico.

Syphilis and HIV infections continue to threaten the safety of blood banks in countries where altruistic donations are rare. The aim of this study of blood donors to the Centro Estatal de la Transfusion Sanguínea de Veracruz (Mexico) was to determine changes in the prevalence of syphilis and HIV, and to identify factors associated with these infections. A total of 109,054 blood donors were retrospectively analyzed from 2007 to 2014.
