An infection carried by cats and transmitted to humans may be responsible for one million traffic-related deaths, according to a 2010 study.
Toxoplasma gondii is a parasite which infects the central nervous system of humans, and can manipulate human behavior. A person can become infected by cleaning a cat’s litter tray, or by eating raw or undercooked meat or unwashed vegetables contaminated by cat feces. Rates of infection have been found to be as high as 30% of the population in eastern Europe, but much lower in Canada and the U.S.
The failure to foresee danger in unsafe situations can be a by-product of the Toxo infection.
