Pathogens that cross from animals to people and then attack the nervous system — and why the decisive signal almost never appears first in a neurology ward.
A pathogen that reaches the human brain has usually travelled a long way to get there. It has circulated in a wildlife reservoir, found an interface created by land use or food production, sometimes passed through livestock, and only then presented as encephalitis in a hospital. By the time a clinician is treating altered consciousness and seizures, the decisive opportunities for prevention are already some distance upstream.
This pathway follows that journey in the direction the pathogen actually travels. It examines the ecological interfaces where spillover becomes possible, the agricultural and food practices that open them, the point at which infection becomes neurological disease, and the surveillance and reporting arrangements that determine whether anyone connects the animal signal to the human one in time to matter.
