TBE in Kyrgyzstan
Wilhelm Erber
E-CDC risk status: endemic
(limited data available)
History and current situation
There is very little information and there are only a few publications on TBE in Kyrgyzstan. A survey by Atkinson1 references the following: In humans and birds low seropositivity has been demonstrated as early as 1973. In 1978 the TBEV was isolated from ticks, and twelve human cases were reported between 1976–1981.
A more recent publication confirmed virus circulation between 2007 and 2009 in local tick populations in Ala-Archa National Nature Park ≈40 km south of Bishkek, the capital of Kyrgyzstan, as well as serologic evidence of a possible human TBE case.2
The TBEV strain isolated from an Ixodes persulcatus tick pool and from liver samples from 2 Apodemus pallipes mice was shown to be of the Siberian (TBEV-Sib) subtype and most closely related to strains from Novosibirsk.2
