Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 24/09/2026Is COVID surging in Ontario? I think it is. Wastewater surveillance lags about 2 weeks (which yes, mostly defeats its purpose). It reads as low/moderate. But in other jurisdictions around us it's surging. Anecdotally, I see a big bump in infections among people I know, just in the last week. 1/4 611749
Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 21/06/2026Feeling a bit vexed today, reading of a large outbreak of viral pink eye at St. Joseph's in Hamilton. By vexed, I really mean livid. Why? To begin with, the reporting was not well done, taking a "these things happen" tone in a case of serious negligence. 1/4 www.thestar.com/news/gta/out...thestar.comSome patients impacted by Stoney Creek pink eye outbreak were notified seven weeks after infectionSt. Joe’s apologizes for the delay as the number of cases rises to 92; the outbreak has been declared over. 56027
Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 09/06/2026I should have pointed out this particular product when I talked about HEPA filters. Small local Toronto business. Entirely quiet devices. Like crazy quiet. Uses standard furnace filters. I have three of them in my house, in the larger common rooms. (Plus a small Levoit unit in every bedroom). 33412
Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 09/06/2026Public health risks during the World Cup haven't received much media attention. But there is a capacity building opportunity here - some basic things to keep in mind to elevate safety. So how can one assess and mitigate risk? A thread ... 1/15 47027
Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 04/06/2026My Toronto Star Op-Ed last week pointed the finger at physician thinking & physician culture to explain why they just won't let go of certain beliefs even when drowning in evidence to the contrary. Today the Globe and Mail provided a tragically shining example, quoting Dr. Srinivan Murthy ... 1/10 517585
Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 28/05/2026Thanks for locating a non-paywall version of my Op-Ed! Just between us, I'm livid at having had many of my words changed over my repeated objections. It does read well, but key changes muted my voice. That's never been done to me before, but better that it get published this way than not at all. 4339

Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 10/05/2026A second hanta-rant in as many days. I'm concerned. That we can't apply what we have learned in dealing with this stricken ship. First objection: ignoring rodents, when rodents are the usual disease vector. Person-person transmission has been assumed AND that rodents aren't involved. Naive. 1/8 59527
Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 08/05/2026Sigh. After a few years of post-COVID peace & quiet, I did two hantavirus interviews today. So here I am. First, to be clear, human-human transmission of hantavirus has been reported several times, but NOT actually proven - in every case those people also had some other exposure in common. 1/7 14711

Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 26/01/2024On Monday I provided a deputation to the Toronto District School Board Planning & Priorities meeting. My 5-minute bit starts at 24:50 (below). Then some Q&A. I felt a readiness to listen at the TDSB. Glad I was given the opportunity. www.tdsb.on.ca/Leadership/B... 3356
Colin Furness MISt PhD MPH @furnesscolin.bsky.social · 26/01/2024I'm not a morning person, but I had perhaps my best-yet radio conversation before 7am this morning with Jonna Brewer (CBC New Brunswick) about public awareness of Long COVID. www.cbc.ca/listen/live-... 2185
