Once inside an animal or human host, the parasite then needs to get back into the cat, the only place where it can sexually reproduce—and this is when, Flegr believed, behavioral manipulation might come into play. The findings were so bizarre that Flegr initially assumed his data must be flawed. The approach brought to light a striking talent of the parasite: it has two genes that allow it to crank up production of the neurotransmitter dopamine in the host brain. Infection did not affect how subjects rated these other samples. The rat may live two or three years, while humans can be infected for many decades, which is why we may be seeing these severe side effects in people. Much more important for preventing exposure, he says, is to scrub vegetables thoroughly and avoid drinking water that has not been properly purified, especially in the developing world, where infection rates can reach 95 percent in some places. Their findings, reported last summer, created immediate buzz. For example, she and Chris Reiber, a biomedical anthropologist at Binghamton University, in New York, strongly suspected that the flu virus might boost our desire to socialize. It might just make you a little less introverted.
