EPIDEMIOLOGIC FEATURES OF NOROVIRUS INFECTION OUTBREAK IN THE REPUBLIC OF NORTH OSSETIA-ALANIA

Aim. Analysis of epidemiologic features of a norovirus outbreak in Alagir city of the Republic of North Ossetia-Alania and effectiveness of measures of its liquidation. Materials and methods. Data from maps-schemes of water supply system of Alagir city and statistical documentation of Centre of Hygiene and Epidemiology in the Republic of North Ossetia-Alania were used in the study. Indication of norovirus in clinical material and water samples was carried out by polymerase chain reaction method. Results. Etiological agent of outbreak disease was established - genotype II norovirus. Realization of fecal-oral mechanisms of water transmission pathway of the causative agent of norovirus infection was detected. Conditions facilitating emergence and development of the indicated outbreak were determined - non-satisfactory sanitary-technical condition of water supply system of the city. Conclusion. The studied water outbreak of norovirus infection was caused by GII.17 genotype virus, that currently gradually displaces GII.IV genotype, and was characterized by an intensive start, involvement of all population age groups into the epidemic process (with primary infection of adults), low family focality, predominance of average severity disease forms in the clinical presentation. The counter-epidemic measures carried out ensured rapid localization and liquidation of the norovirus infection outbreak

Photoluminecsence and Generation of Golmium (Ho) Atoms in the Glassfiber and in the Cristall Media

The purpose of the given message - interpretation of the processes providing a photoluminescence and laser generation in spectral area 2000 nm at use as the active laser environment cristall or glass material, activated by an atomicholmium. Offered in article interpretation is based on use of the law of the conservation of energy, which attraction allows to reveal in an atomic holmium the transitions responsible for a photoluminecsence in specified area of a spectrum (2000 nm).Comment: 2 pages (in Russian
