[The detection of antibodies to the hepatitis C virus and to HBsAg in donors with viral hepatitis and cancerous diseases in the Republic of Moldova]. / Vyiavlenie antitel k virusu gepatita C i HBsAg u donorov, bol'nykh virusnymi gepatitami i onkologicheskimi zabolevaniiami, v Respublike Moldova.

Large-scale and uneven distribution of hepatitis C and B (HC and HB) among free blood donors of different regions of the Moldova Republic was established. The rate of detection of anti-HCV (South 6.2%, North 3.6%) correlated with that of HBsAg detection (south 12.5%, north 4.5%). A great role of HCV in the etiology of acute (among them posttransfusion) hepatitis and chronic hepatitis was demonstrated. A significant frequency of detection of anti-HCV (15%) in children treated in oncohematology wards and receiving multiple hemotransfusions as well as the detected cases of acute posttransfusion HC attest to active realization of this virus transmission in the transfusions of blood and/or its components. The necessity of urgent introduction into the Blood Transfusion Service of the republic of the examination of blood donors for HBsAg, alongside with their examination for the presence of anti-HCV and vaccination prophylaxis of HB in high risk groups is substantiated.

[The results of a study of the contamination of bodies of water by rotaviruses against a background of gastroenteritis morbidity]. / Rezul'taty izucheniia kontaminatsii vodnykh ob''ektov rotavirusami na fone zabolevaemosti gastroénterita.

The results of a sanitary virological survey of the prevalence of rotaviruses in water objects in relation to gastroenteritis incidence are presented. Some regularities of the epidemic process of rotavirus infection were discovered: a high portion of infants involved, occurrence of cases of the disease predominantly in the cold periods of the year, a significant portion (23.8%) of rotavirus gastroenteritis in the total incidence of acute intestinal infections, etc. Besides, comparison of the data on the dynamics of rotavirus infection incidence and on the contamination of water objects with rotaviruses revealed a strong correlation between these data. The possibility of using this information for the evaluation of the epidemiological situation is discussed.

[The possibility for the sanitary removal of enteroviruses from water reservoirs in the case of intensive irrigation agriculture]. / Izuchenie vozmozhnosti sanatsii vodnykh ob''ektov ot kishechnykh virusov v usloviiakh intensivnogo oroshaemogo zemledeliia.

The efficacy of elimination of enteric viruses from water in the process of exploitation of a closed irrigating system is evaluated. Experimental and natural observations showed the half-life of the index virus in the water objects of the irrigating system to be 1.57 days. The potentials of using a temperature-dependent variant of poliomyelitis virus as the internal control in studies of the prevalence of enteric virules among human subjects and in the environment under conditions of intensive irrigated agriculture are considered.

[Computer model for prognosis of incidence of aseptic meningitis]. / Komp'iuternaia model' prognozirovaniia zabolevaemosti seroznym meningitom.

A possibility of construction of a mathematical model for current prognosing of aseptic meningitis incidence both for 2-4 months in advance and for the whole year has been demonstrated. The initial information consisted of the data on prevalence of enteroviruses in water objects as from May. Comparison of the actual and estimated incidence indicates that with the proposed model, up to 90.4% of the incidence of aseptic meningitis may be explained.
