In brief: "Kissing Bugs"
Chagas disease is caused by a parasite (trypanosoma cruzi) transmitted by the triatoma bug (aka: kissing bug).
The bug itself is infected and has the habit of defecating immediately after biting you. While not pretty to imagine, the bugs poop, with the parasite in it, mixes with your blood where you were bitten, and hence you're infected. The bug lives in mud & thatch huts in poor, rural, areas.

In brief: Several ways
Chagas disease can be transmitted to humans by the bite of kissing bugs, blood transfusions, from mother to fetus & by eating food contaminated with the parasites.
Trypanosoma cruzi is the protozoan that is passed by these various mechanisms.
