Mapping tuberculosis

A TV/online interactive package aired Monday on the growing number of tuberculosis cases in the GTA, and the strong neighbourhood patterns shown by the patients’ postal codes.

In general, this kind of map is straightforward to do from a  province’s reportable disease database – the disease and the first three characters of the postal code of the patient are generally releasable (at least in Ontario – Alberta refused to release similar data). You have to keep an eye on the proportion of patients whose postal codes are reported, but in this case we have FSAs for all but 21 of 632 Ontario 2010 TB cases, which seems more than acceptable.
