About surveillance in Georgia
Georgia (the Caucasus country) sits outside the EU/EEA system that ECDC reports on, and its national public-health authority — the National Center for Disease Control and Public Health (NCDC, ncdc.ge) — runs only sparse arbovirus surveillance. West Nile virus is a recognised concern: in 2026 the NCDC began its first targeted WNV study in birds and mosquitoes, but no national human case count has been published. The Asian tiger mosquito (Aedes albopictus) and Aedes aegypti are established on the Black Sea coast.
Frequently asked questions
What mosquito-borne diseases is Georgia monitoring in 2026?
Mosticare tracks Georgia surveillance for West Nile virus, each sourced to the responsible national authority or ECDC.
How many West Nile virus cases are reported in Georgia?
No recent national count of locally-acquired (autochthonous) human West Nile virus cases has been published for Georgia. The country is not part of the EU/EEA system that the European Centre for Disease Prevention and Control (ECDC) reports on, and its National Center for Disease Control and Public Health (NCDC) runs limited arbovirus surveillance. In 2026 the NCDC, through the OneHealthSecure programme, started what it describes as the first targeted investigation of WNV in Georgia — screening birds and mosquitoes to build baseline data. An earlier hospital study of febrile patients (2008-2011) found no WNV-positive cases among those tested. Because no reliable national figure exists, we report this honestly as a qualitative status rather than inventing a number.
Which mosquito species carry disease risk in Georgia?
The main West Nile virus vector across the region is the common house mosquito (Culex pipiens). Separately, two invasive day-biting species — the Asian tiger mosquito (Aedes albopictus) and Aedes aegypti — are documented as established on Georgia's Black Sea coast and inland (including around Tbilisi and Batumi) in peer-reviewed entomological surveys. These Aedes species can transmit dengue, chikungunya and Zika, which is why researchers flag the Black Sea Caucasus as an area at future risk of these diseases, even though no locally-acquired dengue, chikungunya or Zika has been reported in Georgia to date.
Has there been a dengue or chikungunya outbreak in Georgia?
No locally-acquired (autochthonous) dengue, chikungunya or Zika outbreak has been reported in Georgia. Chikungunya cases recorded in the country have been associated with international travel rather than local mosquito transmission. The presence of established Aedes albopictus and Aedes aegypti on the Black Sea coast means the potential exists, which is why surveillance is expanding — but as of 2025-2026 there is no documented local transmission of these viruses in Georgia.

About this data
Mosticare aggregates and re-publishes vector-borne disease surveillance from ECDC, EFSA, and national ministries of health. Mosticare is an aggregator, not a primary surveillance authority — every figure on this page cites the originating source and is independently verifiable. This is a partial aggregation; for the complete EU/EEA totals, ECDC is the primary source.
The data behind this page is published as free, machine-readable feeds under CC BY 4.0 — the point-in-time incidence snapshot at /threat-map/feed.json (JSON Schema) and the multi-year trends at /threat-map/feed/trends.json (JSON Schema). See the live Europe threat map and the full data room.
