The perinatal transmission of hepatitis C virus (HCV) is the major route of infection in infants. The understanding of the risk factors of perinatal infection and the continuation of studies in this area allow one to propose immunological algorithms of prediction and to work outa follow-up strategy of infected children. The authors have made virological and(More)
BACKGROUND The Global Influenza Hospital Surveillance Network was established in 2012 to obtain valid epidemiologic data on hospital admissions with influenza-like illness. Here we describe the epidemiology of admissions with influenza within the Northern Hemisphere sites during the 2013/2014 influenza season, identify risk factors for severe outcomes and(More)
The Global Influenza Hospital Surveillance Network (GIHSN) has established a prospective, active surveillance, hospital-based epidemiological study to collect epidemiological and virological data for the Northern and Southern Hemispheres over several consecutive seasons. It focuses exclusively on severe cases of influenza requiring hospitalization. A(More)
In the 2015-2016 epidemic season, there were dominant influenza A(H1N1)pdm09 strains (over 90%) among the circulating influenza viruses in most countries of the Northern Hemisphere and in Russia. A study of the antigenic properties of influenza A(H1N1)pdm09 strains revealed no differences in those of vaccine virus. Sequencing showed that there were amino(More)
Changes of the immune status are decisive in the pathogenesis of cytomegalovirus infection, which is a cause for the intrauterine infection. Therefore, complex immunological and virological examinations are advisable to make in pregnant women with compromised obstetrics history, pathological pregnancy course and with indirect signs of intrauterine fetus(More)
The results of analysis of the peculiarities of the epidemic 2011-2012 development in the areas of 10 cities of Russia obtained by basic laboratories of IEES on the base of D.I. Ivanovsky Research Institute of Virology, Ministry of Public Health and Social Development of Russia, are presented. The increasing ARD morbidity caused by the influenza viruses was(More)
The paper gives the results of monitoring the circulation of influenza viruses in the 2010-2011 season, that covers the second year of circulation of pandemic A(H1N1)v virus strains, and their interaction with seasonal A (H3N2) and B strains. Unlike the previous season, the beginning of an increase in morbidity was recorded in January 2011; its peak in the(More)
The therapeutic effect of aerosol virasol was studied in young infants suffering from RS virus infection with concomitant broncho-obstructive syndrome. The study involved 60 children between 1 month and 4 years of age of whom 30 were treated with virasol and another 30 made a control group. Virasol was shown to reduce the severity of the clinical picture to(More)
AIM To characterize the 2013-2014 epidemic season from the results of detection of influenza infection in patients; to provide the molecular genetic characteristics of the strains isolated from deceased patients. SUBJECTS AND METHODS The investigators examined 1203 patients (387 children, 509 people older than 16 years of age, 307 pregnant women) admitted(More)
The goal of this work was to present the data of the study of the peculiarities of the generation factors of humoral immunity in the response to the infection with the pandemic influenza A (HIN1) pdmO9 in patients with different epidemiological anamnesis. High ability of the influenza viruses to spread over closed communities and the transfer of the(More)
