To assess local circulation and risk for human infections with West Nile virus (WNV) and Tick-borne encephalitis virus (TBEV) in Bulgaria, a nationwide seroprevalence study was conducted. In total, 1451 residents of all 28 districts in Bulgaria were tested for WNV-specific and TBEV-specific IgG antibodies. The survey found overall seroprevalence of 1.5% and 0.6%, respectively. The highest WNV seroprevalence was found in Sofia Province and districts near the river Danube. TBEV circulation was detected among residents of six districts. The results showed that the two virus infections seem to be more wide-spread in the country as has been described.
为了评估保加利亚境内西尼罗河病毒(WNV)和蜱传脑炎病毒(TBEV)的局部循环和人类感染风险,开展了一项全国范围的血清流行率研究。共有 1451 名保加利亚所有 28 个区的居民接受了 WNV 特异性和 TBEV 特异性 IgG 抗体检测。调查发现,WNV 和 TBEV 的总体血清阳性率分别为 1.5%和 0.6%。WNV 血清阳性率最高的地区是索菲亚省和多瑙河附近的地区。TBEV 的传播发生在六个区的居民中。结果表明,这两种病毒感染在该国的传播范围似乎比之前所描述的更为广泛。
