Mapping STIs by postal code

by Patrick Cain

Global Toronto ran a story Friday on the resurgence of syphilis and rise of drug-resistant gonorrhea in Toronto.

We were able to map four STIs by postal code to go with the story: syphilis, gonorrhea, HIV and chlamydia.

We’re working with a boundary set that covers the whole province, so it was easy enough to generate views of Hamilton and Ottawa as well.

Gonorrhea and chlamydia are common in the broader downtown, in a part of the city’s northwest stretching north along Jane St., Brampton, and eastern Scarborough.

Syphilis and HIV have very similar patterns to each other both tightly concentrated in the east downtown. The data itself came from a redacted version of the Ontario infectious disease database obtained under FOI.

Here’s how it looked on TV.
