Circulation of influenza virus A(H1N1) in Moldavia (Romania) during 1978-1982.

The influenza virus A(H1N1) subtype that reappeared after an absence of 20 years was incriminated as an etiological agent of acute respiratory disease outbreaks in Moldavia (Romania). There were three epidemics in the winter--spring of 1978, 1979, and 1982, that affected mostly school communities and young adults. In 1980-1981 the circulation of A(H1N1) virus was limited. In all the epidemics mentioned the A(H1N1) subtype caused mild influenza cases, with minimal complications and insignificant mortality.

[Epidemiological observations on the evolution of influenza in the city of Iaşi in the epidemic season of 1993-1994].

The epidemiological, clinical and laboratory data of influenza and other respiratory diseases recorded during the epidemic season 1993-1994, as they resulted from the comparative analysis of the cases reported weekly and those recorded through the "sentinel" collectivities method, are presented. The findings at admissions to the Infectious Diseases Hospital, Military Hospital, Diagnosis and Treatment Centre for Pupils and Students and the solicitation for medical care at the Emergency Ambulance Service were also interpreted. The involvement of A/Beijing/32/92/(H3N2) influenza virus was confirmed by evidencing the seroconversion on two serum samples tested through RIH, while for others antigens anamnestic reactions were recorded. The influenza epidemic had affected all age groups, with horizontal extension, a first rise in December 1993 followed by the decline determined by winter vacation being notice. A second epidemic rise, much stronger, started beginning with the last month of January and reached a peak at mid February, followed by a marked decline.

Efficacy of multidisciplinary epidemiological screening in the primary prevention of essential arterial hypertension.

An epidemiological screening of 8011 industrial workers and 7090 pupils made possible the active detection of some risk factors carriers and of those individuals with borderline essential arterial hypertension (BEAHT) and essential arterial hypertension disease (EAHTD). It was noticed that the association of 2-4 risk factors is more common in the subjects with BEAHT or EAHTD, fact indicating their increased aggressivity in the various types of associations present in the same carrier. In the worker series a prevalence of 16.2%-18.0% for BEAHT and 6.3%-7.1% for EAHTD as compared to 4.3%-6.0% and 4.9%-5.3%, respectively, in the pupil series were recorded. The epidemiological screening had a strong educational effect, reflected in an increased cooperation of the screened population, and revealed the fact that the risk factor carrier state and the increased arterial pressure levels were ignored, at long term, by 50-90% of the investigated subjects.

[Seroepidemiological considerations of the incidence of viral hepatitis C in some population groups].

In the interval 1985-1994, in the Iaşi district, the reported cases of viral hepatitis (VH) have recorded annual morbidity rates ranging between 67/100,000 inhabitants in 1993 and 373/100,000 in 1990. VH attributed to HAV and HBV has represented, with yearly differences, 62% to 94% of all cases. Posttransfusion viral hepatitis (PTVH) has determined a morbidity of 0.51/100,000 inhabitants in 1986 and 8.34/100,000 in 1994. PTVH without AgHBs ranged from 16.3% in 1993 to 94.0% in 1987, as compared to 6.0% in 1987 and 1988 and 75.0% in 1985 for PTVH with AgHBs. In the interval under study 70.9% of the PTVH cases were most likely determined by HCV and 28.9% by HBV (AgHBs+). From all PTVH cases, 64.0% were from urban areas, 59.3% were females, 92.5% belonged to over 20 years age groups, and 31.3% were industrial workers, the remainder belonging to other 5 occupational groups. In 241 patients (18.2%) admitted for liver disorders, posttransfusion hepatitis included, AcHCV was present in 39.4%, of which 45.2% belonged to the age groups 20-60 years. The results of some investigations carried out on 4471 blood donors (72.4% males, 85.4% aged between 21 ad 50 years, 86.4% from urban areas, 62.1% workers in industry and building) are presented. Out of these, 217 (4.9%) presented to hepatitis C virus (AcHCV). Occupational distribution of AcHCV possessors shows that 44.2% are workers in the heavy industry, 14.8% in the light industry and 12.9% unemployed. Sera were tested by Monolisa New Antigens, and those with AcHCV were reassessed with Monolisa, Murex anti HCV, ORTO-HCV 3.0 and confirmed by Immunoblot DECISCAN, with 5 antigens.
