Back­ground. ­Tick ­borne enceph­al­itis ­(TBE) virus is dif­fused in ­some Euro­pe­an coun­tries and it is trans­mit­ted by ­tick ­bites. In Ita­ly Iso­dex ric­i­nus rep­re­sents the ­main vec­tor of the infec­tion, ­that rare­ly pro­duc­es the neu­ro­log­ic man­i­fes­ta­tions, char­ac­ter­is­ing the sec­on­dary ­phase of the ­same.
Meth­ods. In Ita­ly TBE has ­been lit­tle stud­ied and ­this ­only in the Mid­dle and North­ern ­regions of the coun­try. Ser­oe­pid­e­mi­o­log­i­cal research­es ­were ­done prev­al­ent­ly on sub­jects at ­high ­risk of ­tick ­bite, ­such as hunt­ers or for­est ­guards and espe­cial­ly in Tren­ti­no and Tus­ca­ny. No pre­cise infor­ma­tion ­about TBE ­virus dif­fu­sion was dis­pos­able in the Pied­mont ­region and par­tic­u­lar­ly in the ­Susa val­ley ­where, ­before our inves­ti­ga­tion ­failed the ­data ­about it.
­Results. We ­found ­that usu­al hunt­ers and ­wild ­boar breed­ers ­seem to be par­tic­u­lar­ly ­exposed to the ­risk of TBE ­virus infec­tion, but ­none neu­ro­log­ic involve­ment was detect­ed in the anam­ne­sis of the sig­nif­i­cant­ly ser­o­pos­i­tive sub­jects and ­also of the bor­der­line ­ones, ­that we ­have stud­ied, ­despite the lim­it­ed num­ber of ­these sub­jects.
Con­clu­sions. Nev­er­the­less we ­hope for a fol­low­ing exten­sion of our ­case ­report, ­also in con­sid­er­a­tion ­that ­rare cas­es of enceph­al­itis of ­unknown eti­ol­o­gy, are sig­nalled in Pied­mont.
