Sien Lagae of Belgium has only 20 percent of lung capacity. She was already careful to avoid viruses even before the COVID 19 crisis. Lagae has depended on caregivers for years. They help her get dressed, clean her house and provide her with health care at her home. Recently, one of her caregivers told Lagae she had paid 10 euros for a mask to protect herself and others from the virus. That gave Lagae, who loves to sew, an idea. I had the idea to make some face masks for my physiotherapist so that she could protect herself and her patients better, Lagae said. What started as a one person operation about a week ago has grown into a small army of at home Belgian mask makers. Lagae opened the effort with a Facebook page called Sewing Mouth Masks. She had 3,000 members within two days. On Friday, that number rose to 5,300.
