Vernon Morning Star: One of Chilliwack’s ER doctors has been tapped to explain the pros and cons of different masks. Dr. Marc Greidanus is featured in a short, upbeat video where he tries on and quickly explains each style, from cloth masks to full face shields. He also reminds viewers that the topic is serious. “COVID is real and it’s here,” he says. “We’ve been asked to wear a mask and it’s not that hard.”
