Le regioni a rischio zecche sono sempre più estese in Svizzera. A tal punto che la Commissione federale per le vaccinazioni è pronta a raccomandare il vaccino a tutti i cittadini del paese, Ticino escluso. Un vaccino per contrastare il virus che veicola la meningoencefalite, infezione provocata proprio dalle punture di zecche.
Il Ticino non è incluso perché al momento non è considerato tra le regioni a rischio. Le zecche presenti a sud delle Alpi non sarebbero infatti portatrici di virus o batteri.
Il virus che veicola la meningoencefalite si rivela mortale in circa l’1% dei casi. Il vaccino costa tra i 2 e i 300 franchi. Costi che vengono assunti dagli assicuratori malattia. I benefici, procedendo alla vaccinazione, sono tangibili (per rapporto ai costi). Nei primi 7 mesi di quest’anno, in Svizzera, sono già 230 le persone che sono state infettate dal virus: il doppio rispetto all’intero 2017.
