Case counts have a long way down to go, meaning many more infections are expected in the coming weeks.

Two years since Covid was first confirmed in U.S., the pandemic is worse than anyone imagined

A 35-year-old man returned to the U.S. from Wuhan, China on Jan. 15, 2020 and fell ill with a cough and fever. He had read an alert from the Centers for Disease Control and Prevention about an outbreak of a novel coronavirus in Wuhan and sought treatment at an urgent care clinic in Snohomish County, Washington four days later.

When will Omicron peak? A Penn State professor shares national COVID-19 modeling team's projections

Katriona Shea, an Alumni Professor in the biological sciences at Penn State, is co-leader of the COVID-19 Scenario Modeling Hub Coordination Team. It brings together researchers from institutions across the United States to offer projections on the pandemic and advise the Centers for Disease Control and Prevention. WPSU’s Anne Danahy spoke with Shea about what we might expect from Omicron and the pandemic.
