Alexis Misko’s health has improved enough that, once a month, she can leave her house for a few hours. First, she needs to build up her energy by lying in a dark room for the better part of two days, doing little more than listening to audiobooks. Then she needs a driver, a quiet destination where she can lie down, and days of rest to recover afterward. The brief outdoor joy “never quite feels like enough,” she told me, but it’s so much more than what she managed in her first year of long COVID, when she couldn’t sit upright for more than an hour or stand for more than 10 minutes. Now, at least, she can watch TV on the same day she takes a shower.
