Epidemiological Significance of Hantavirus Infection in Crimea
Objective of this work was to determine epidemiological significance of Hantaviruses, circulating in Crimea, on the basis of retrospective data and taking into account the results obtained over the monitoring period of 2015–2018.Materials and methods. The study of small mammals and blood sera of don...
