One of the most dimensionally comprehensive in state and profound in effect of all pathogens, the physical symptoms of Love were, though extreme, in fact largely unremarkable: a brief initial period of insanity rarely lasting beyond six to twelve months and manifested as increased sexual desire, excessive or decreased appetite, emotional instability and obsessive behaviour; a secondary state of several years when the initial symptoms decreased to a naturally occurring rate as the brain’s capacity for logic and reason recovered sufficiently to fight the infection, before the final exhaustion of the virus’s life-span and cessation of its physical effects. However, it is the transmission of this particular virus that betrays its quantum nature.

Often Love infects not one, but two hosts simultaneously, activating both individuals’ latent telepathic abilities in order to sustain itself symbiotically. The same virus is thus able to be in two places at one point in time. Each infected party would then become, by result of infection and to an unimpaired third party: capable of finishing each other’s sentences; reading each other’s thoughts and providing for the otherwise unanticipated actions of one another. Where it infects only one person, the behavioural effects are similar to a toxoplasmosis infection, where the host will actively seek out that which will consume them.

Once infected, Love never entirely leaves the body. It instead (after the aforementioned primary and secondary stages) recodes itself as a memory engram and lies dormant in the host’s brain. Reinfection can occur in a state of quantum resonance with the same spatial plane, such as visiting a location whilst previously infected or if the virus is transferred to another person.
