When the coronavirus first flared up across Maine last spring, many of the state’s frontline health care workers were scared by how little they knew about it. Would they have enough face masks and gowns? Would they bring the virus home to their loved ones? Would they die from it? And how quickly would the strange new infection storm across a rural state whose large elderly population was particularly threatened by it? The answers to all of those questions have become clearer over the last eight months, as the virus initially surged from March through June before petering out in early July, causing slightly more than 100 deaths.
