Phthisiatry is the study of tuberculosis. The term is used primarily in Eastern European and Russian science.
It dates back to The Canon of Medicine written by Ibn Sina (Avicenna) in the 1020s. He was the first physician to identify pulmonary tuberculosis as a contagious disease, the first to recognise the association with diabetes, and the first to suggest that it could spread through contact with soil and water.[1][2] He developed the method of quarantine in order to limit the spread of tuberculosis.[3]
