There are several measles cases in Waterloo Region. As of last week there were currently over 60 cases in nearby Wellington/Guelph, and over 1,300 in Ontario since October.
Measles is like Covid in that there's an incubation period in which people have no symptoms but are contagious. Viruses are stealthy! For measles, it's 7-12 days from exposure to symptoms like fever or cough, so it's really important to track cases and isolate if potentially exposed. For Covid, it can be 5-7 days before it's picked up by a rapid test, and you can have it and spread it without any symptoms at all. Both cause serious complications, including brain infection, and leads to death in about 1 or 2 in 1,000 people.
Both can be prevented with an N95.
The biggest difference between these viruses is that getting vaccinated is extremely good protection for measles, but not for Covid. If you got your measles shots, you're very likely completely protected. Unfortunately, vaccination rates are plummeting. We need to have at least 94% of the population vaccinated to create herd immunity and keep measles at bay, and Ontario has been hovering in the 70s since Covid started and anti-vaxx nonsense got a platform. Vaccination against Covid does a lot to keep people out of the hospital, but it doesn't prevent getting and spreading the disease because, like the flu, Covid mutates all the flippin' time. Measles is just measles, but Covid could be delta, or alpha, or one of many omicron variants, or whatever's going on now. It changes so much I stopped keeping track. The more it spreads, the more it mutates, and we're doing nothing to stop the spread.
