Objective
The objective of this study was to analyze the epizootic potential of four areas of
Tavush Marz.

Introduction
Tavush Marz, in northeastern Armenia, occupies 9,1% of its territory. In recent years
in this area either no surveys were conducted or they were incomplete. Tavush Marz
is a tourism center as well as a border Marz with strategic importance. The presence
of tularemia was first confirmed in 1949 in Noyemberyan. Natural foci of tularemia
are located in forest zones where Sylvemus uralensis and its flea
vectors are the source of infection.

Methods
Tests were conducted in four areas of Tavush Marz. Materials for laboratory analyses
were collected via sampling from animal populations and their nests; insect traps,
nets, aspirators were used as well. Collected rodents, fleas and mosquitoes were
tested on the presence of natural foci especially dangerous infections. The acquired
data with coordinates of collection sites were included in the geographic
database.

Results
The first detection of the Aedes albopictus species of Culicoidea
subfamily in Armenia was on the border between Noyemberyan and Georgia in 2016; this
is a vector of especially dangerous infections and arboviruses. The presence of the
mosquito was confirmed in 2017 and it makes up 13.5% of the mosquitoes collected in
the northeast. It is capable of transmitting the chikungunya, Dengue, and West Nile
viruses. Since the end of 2015, we have recorded a significant increase in carriers
and vectors, mainly S. uralensis, Microtus
socialis, and ectoparasites specific to them. In October 2016 six cases
of infection with tularemia were recorded in the village of Tsakhkavan in Tavush
region and in Bagratashen Village of Noyemberyan region in 2017.

Conclusions
Analysis of the density of rodents and vectors, as well as their typical
ectoparasites leads us to conclude that there are favorable conditions for the
spread of not only tularemia but also other natural foci infections and that a
comprehensive and regular epizootological survey is required to control this
situation.
