Encefalitis virales transmitidas por garrapatas: ¿Están lejos de las Américas?

Tick-borne viral encephalitis: are they far from the Americas?

Dentro de las variadas patologías del Sistema Nervioso Central (SNC), las dos entidades clínicas más importantes por su frecuencia de aparición en el mundo son las meningitis y las encefalitis. Las infecciones del SNC constituyen un reto diagnóstico porque las manifestaciones clínicas no son normalmente patognomónicas y existen diversos agentes etiológicos implicados. Solamente se logra determinar entre el 40-70% el agente etiológico de los casos de las encefalitis y en menos del 0.1% se logra aislar un virus diferente a los enterovirus o herpesvirus (1).
