    Long time Lyme disease patient advocate warns Nova Scotians about ticks and medical practices

    ByCanLyme May 18, 2019July 27, 2020

    [CanLyme Note: Here we are in 2019 and doctors are still telling patients not to worry about a tick attachment. Ticks are nature’s dirty little needle and they carry much more than just Lyme disease.  Some of these other diseases can be transmitted shortly after attachment. Watching and waiting only allows disease to spread making treatment…

    Where Lyme Disease Came From and Why It Eludes Treatment

    ByCanLyme May 17, 2019July 27, 2020

    [CanLyme Note: The title is a bit misleading.  The bacteria that causes Lyme disease is millions of years old according to research.  Why it spread so quickly in the past 60 years is the question, and climate change (warming) only accounts for some of that spread because countries with colder climates than Canada have had Lyme…
