This week, we continue our disease series by looking at hepatitis B and C.
Hepatitis B (map) clusters in a stretch of downtown south of Bloor stretching east from Bathurst, and across the Don into south Riverdale. In the suburbs, there is a cluster centred more or less on Warden and Steeles, between Bayview and Markham Rd.
Hepatitis C (map) has three clusters - the east downtown through south Riverdale, the Beaches and eastern East York, with Thorncliffe Park; lake shore Etobicoke generally, with an area east of Dixie Rd. north to Burnamthorpe; and the area north and west of Pearson.
