Research conducted in 2010 showed flu viruses hijack the nervous systems of people when they're still asymptomatic and prompt them to go out and be sociable, just when they are most contagious. And thus infecting others. Professor, Glenn Geher from New York State University is an evolutionary behavioural scientist – a Covid-19 survivor himself, wants more research done to figure out if this happens with this virus – and why. He tells Karyn why this is important and what mice infected with the parasite, Toxiplasma Ghandii, have in common with flu patients.
