| Description | A total of 497 residents in the area affected by the flood were screened for antibodies against mosquito-borne viruses Tahyna (TAHV), West Nile (WNV), Sindbis (SINV) and Batai (BATV; syn. Calovo) using the haemagglutination-inhibition (HIT) and plaque-reduction neutralization (PRNT) tests. Antibodies were detected against TAHV (16.5% persons in PRNT, 14.9% in HIT), SINV (1.4% in HIT) and BATV (1.4% in HIT, 0.2% in PRNT). Although 6.8% and 1.2% of the subjects tested reactive with WNV in HIT and PRNT, respectively, the results were interpreted as cross-reactivity with tick-borne encephalitis virus. The seroprevalence to TAHV increased with age and correlated with the peri-residential challenge with mosquitoes. The highest TAHV seropositivity rate (> 25%) was found amongst the inhabitants along the river Labe nearby Neratovice (a natural focus of Valtice fever, i.e. TAHV infection). |
