In industrialized populations, Hodgkin's disease (HD) has an initial peak in young adulthood, whereas in economically developing populations the initial peak occurs in childhood. This pattern resembles that of infection with poliovirus and suggests an infectious cofactor in the etiology. Serologic studies have linked Epstein-Barr virus (EBV) to young adult(More)
BACKGROUND Despite the disease burden imposed by respiratory diseases on children in Central America, there is a paucity of data describing the etiologic agents of the disease. AIMS To analyze viral etiologic agents associated with influenza-like illness (ILI) in participants reporting to one outpatient health center, one pediatric hospital, and three(More)
The etiology of acute respiratory tract infection and its association with diarrhea was analyzed in 135 hospitalized children less than three years of age with mainly respiratory symptoms in two pediatric hospitals in Honduras and El Salvador. Etiologic diagnoses were performed on nasopharyngeal samples by tissue culture and immunofluorescence, including a(More)
Although the recent Zika virus (ZIKV) epidemic in the Americas and its link to birth defects have attracted a great deal of attention, much remains unknown about ZIKV disease epidemiology and ZIKV evolution, in part owing to a lack of genomic data. Here we address this gap in knowledge by using multiple sequencing approaches to generate 110 ZIKV genomes(More)
BACKGROUND Monitoring infectivity markers in multi-transfused patients is an important indicator of the efficiency and quality of testing in blood centers. This study is part of a regional initiative to bring both national and regional attention to the problem of hepatitis C, compare the threat of HCV to that of HBV and HIV; assess the risks for viral(More)
The seroprevalence of human immunodeficiency virus (HIV) infection and syphilis was investigated in 181 female prostitutes in Tegucigalpa, Honduras. One particle agglutination test and two enzyme immunoassays, as well as one immunofluorescence test were used for the screening of HIV antibodies. Confirmation of positive results by the screening tests was(More)
INTRODUCTION We assessed HIV drug resistance (DR) in individuals failing ART (acquired DR, ADR) and in ART-naïve individuals (pre-ART DR, PDR) in Honduras, after 10 years of widespread availability of ART. METHODS 365 HIV-infected, ART-naïve, and 381 ART-experienced Honduran individuals were enrolled in 5 reference centres in Tegucigalpa, San Pedro Sula,(More)
BACKGROUND Migration and travel are major drivers of the spread of infectious diseases. Geographic proximity and a common language facilitate travel and migration in Mesoamerica, which in turn could affect the spread of HIV in the region. METHODS 6092 HIV-1 subtype B partial pol sequences sampled from unique antiretroviral treatment-naïve individuals from(More)
