It's all in here: "Zombie Animals and the Parasites that Control Them." The virus jumps from rat to cat. Cat feces enters the human food chain by tainting under-cooked meats in the home.
Estimates are 1 in 5 carry the virus in the brain. Those infected may be developing dangerous fantasies and acting out. Recall the 2007 sequel "I Am Legend" starring Will Smith?
As early as 2003 the CDC linked Toxoplasma to changes in human behavior, including neuroticism, increased aggression and schizophrenia.
For now the CDC is downplaying the problem. But why not test the cannibals and crazies shooting kids in school for the virus? Oh that might produce a result - nevermind.
