Public Health Ontario is reporting 101 confirmed monkeypox cases across the province, up from 33 cases two weeks ago.
A summary report on the disease up to July 4 says there are also eight probable cases in Ontario.
The report says 85 cases are in Toronto, with more than one case each in health units covering Ottawa, Halton Region and Middlesex-London.
Health units in Hamilton, Durham Region, Eastern Ontario, Haldimand-Norfolk, Peel Region, Peterborough, Simcoe-Muskoka and Guelph also confirmed single cases.
All reported cases are in men between the ages of 20 and 65 and commonly reported symptoms include rash, oral and genital lesions, swollen lymph nodes, headache, fever, chills, myalgia and fatigue.
Public health says most cases are among men who report intimate contact with men but says anyone can get monkeypox.
