And nearly all of the viral-disease pairings involved “neurotropic” viruses—those that can invade the central nervous system, such as herpes simplex and herpes zoster and some strains of influenza.

Our research team has overcome this challenge by using neurotropic viruses, which specifically target neurons, as transneuronal tracers.

Changes in vital signs and in neuroendocrine, neurotropic and inflammatory biomarkers could yield insights that are unavailable to clinicians today.

Officials say the strain confirmed in the horse was the neurotropic form of EHV-1, which can cause severe neurological problems in horses.

Chan said the WHO can now conclude that the virus is neurotropic, meaning it attacks the nervous system, "preferentially affecting tissues in the brain and brain stem of the developing fetus."
