Investigations on the presence of antibodies to several alphaviruses in humans and domestic animals of a region with elevated epidemiological potential.

The paper reports on serological results obtained by HAI tests against several alphaviruses - eastern equine encephalitis (EEE), western equine encephalitis (WEE), Chikungunya, Midlebourg, Semliki Forest, Sindbis, and Ilheus viruses - carried out in humans and some domestic animals in a region with an intensive circulation of migratory birds. It was possible to detect in human antibodies to EEE, WEE, and Sindbis viruses, but in very low proportions (1.8%, 0.

Investigations on the presence of antibodies to several flaviviruses in humans and some domestic animals in a biotope with a high frequency of migratory birds.

Data are reported on the presence of HAI antibodies to several flaviviruses (tick-borne encephalitis, West Nile, and Ntaya viruses) in humans and some domestic animals in a biotope with a high frequency of migratory birds. The results obtained prove the presence in humans of specific antibodies in a proportion of 11.8% to tick-borne encephalitis and of 25.
