[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.

Investigations on the efficacy of two schemes of standard gammaglobulin administration in the prevention of viral hepatitis.

Prophylactic administration of standard gammaglobulin (G) to over 5,000 children led to a more than 6-fold decrease in the incidence of icteric viral hepatitis (V.H.) as compared with the control group and to the disappearance of the autumn--winter epidemic peak. A 3-fold decrease in the incidence of subclinical forms was also achieved. In another group of 5,000 children G was only given to contacts in epidemic foci; the incidence of icteric V. H. was similar to that recorded in controls, while subclinical forms were 2 times more frequent in children having received G after the infectant contact.
