The early roots of Institute of Tropical Disease Universitas Airlangga (ITD UA) can be traced back from a research collaboration with Kobe University, Japan, under the scheme Large Scale Collaborative Study. It was named Tropical Disease Research Center (TDRC), but since then it also established its function as diagnostic unit named with TDDC (Tropical Disease Diagnostic Center), TDRC was changed into Tropical Disease Center (TDC). Since 2008, this unit became institute, directly under the supervision of Rector of Universitas Airlangga, named ITD UA. With these roots and also several international research collaborations thereafter, it is no surprise that ITD become a prominent institution in tropical and infectious disease researches and specific related diagnostics – hosting inbound (national and international) postgraduate student researches.
