This review describes the current situation on highly pathogenic avian influenza virus in 2019 and predicts the possible further spread of avian influenza in Russia. In 2019 outbreaks were reported among wild birds and poultry, as well as human infections with influenza viruses of the subtypes H5Nx, H7N9 and H9N2 in several countries. In 2019, only two outbreaks of highly pathogenic avian influenza H5N8 in Russia occurred. Both outbreaks were recorded in January at poultry farm in the Rostov Region. In addition, in May 2019 avian influenza virus of H14N7 subtype was isolated from a wild bird during the avian influenza virus surveillance in Tomsk Region. In June 2019, a strain of H13N2 subtype was isolated in the territory of Kamchatka Region, then, in August 2019, an influenza virus of H13N6 subtype was isolated in the Saratov Region. It was revealed that some strains of avian influenza virus isolated in Russia have a high degree of identity with strains circulating in South-East Asia. This was shown by the phylogenetic analysis of A/ H5Nx influenza viruses previously isolated in the Saratov Region and the Socialist Republic of Vietnam during the avian influenza virus surveillance. Thus, it was demonstrated again that the territory of Russia plays a key geographical role in the global spread of avian influenza virus.
Проблемы особо опасных инфекций. 2019; 1 ОБЗОРЫ 42 вирусы гриппа относятся к семейству Orthomyxoviridae, которое включает четыре вида вирусов гриппа -A, B, C и D [1]. при этом, только вирусы гриппа а способны инфицировать широкий круг восприимчивых хозяев и представляют серьезную угрозу сельскому хозяйству и общественному здравоохранению. вирусы гриппа а подразделяются на субтипы на основании антигенных различий в поверхностных гликопротеинах. на сегодняшний день известно 18 субтипов гемагглютинина и 11 субтипов нейраминидазы. большинство известных комбинаций сохраняется в популяциях диких птиц, которые, как известно, считаются основным природным резервуаром вируса гриппа а [2, 3]. основную роль в

In the study blood collected from 260 residents in X commune (Gio Linh, Quang Tri) is examined for HBsAg by ELISA method and HBV-DNA by real - time PCR. It is found that HBsAg carrying rate is 11.15% (29/260), 13.04% for males and 10.12% for females (p > 0.05); 11.15% of the residents (29/260) are HBV-DNA positive, in which 15.22% for males and 8.93% for females. The rate of HBV-DNA positive in subjects with HBsAg (+) is 79.31% (23/29) and in subjects with HBsAg (-) is 2.60% (6/231).
Two automatic program-apparatus complexes including Ritm-MET and Egoscop were used to assess the psychophysiological and cognitive characteristics of different worker groups of in various professional activities, including a group of soldiers working under extra-hard and dangerous conditions. The results of the study indicated that these complexes provide opportunities for safely, quickly, simply, effectively, objectively evaluating psychophysiological characteristics. The obtained data have a high level of information and predictability. The two devices can be supported to traditional health assessment methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
