Question: In what part of the human body does the parasite live?

Divya Venkatesh answered on 10 Mar 2014:

Different sorts of parasites can live in different places in the body – eye, intestine, brain, blood, liver etc. The trypanosomes I study stay in the blood to begin with. And then, days, months, sometimes years later, they manage to enter the nervous system and live and multiply there. At this point, it’s really hard to get rid of them (the drugs we have are not good enough yet) and the infected person dies if she or he is not treated.
