Mosquito-borne virus infections, such as West Nile and Zika, have debilitating cognitive effects that persist despite recovery from encephalitis. Garber et al. identify mechanisms by which antiviral T cell persistence after recovery from infection leads to impairments in cognition via virus-specific mediation of microglial synapse elimination.
