Officials with an Omaha homeless shelter say more than 250 residents are in quarantine or isolation following a coronavirus outbreak there. Linda Twomey is executive director of the Siena Francis House. She tells the Omaha World-Herald that about 255 residents have been in quarantine or isolation for about two weeks. Twomey says the shelter's latest count showed 54 residents had active COVID-19 cases. She says the shelter has been testing its clients and noticed a surge in positivity rates about 10 days to two weeks ago, prompting the quarantine. She says about 100 residents left the shelter rather than quarantine. The shelter currently is closed to new admissions.
