(It took some time to gather data on this 2015 event but here we go.)
Toxic haze deaths from July to October 2015 were concentrated in Indonesia, with deaths from cardiovascular disease, and some by respiratory disease. (I wouldn't call it "respiratory disease", disease takes longer than that to appear. I'd call it "severe/fatal respiratory distress".) Fires were set by farmers all over the region to clear land for agriculture.
