Interesting new data from NYC - 215 pregnant women were tested for COVID-19 upon admission. 33 tested positive at arrival (15%), and of those who tested positive, 26/34 had no symptoms during stay (76%). Via @petrakle https://www.nejm.org/doi/full/10.1056/NEJMc2009316

Of course, risk in pregnant women might not be representative of wider population, and some may have developed symptoms after stay. But pattern consistent with @_nickdavies @rozeggo et al estimate of lower symptomatic proportion in younger groups https://www.medrxiv.org/content/10.1101/2020.03.24.20043018v1
