​Public health laboratories across the US were consumed by COVID-19 diagnostic testing in the pandemic’s early months. But after clinical laboratories began to do most of the testing, and as more people tested themselves at home with rapid antigen tests, public health laboratories shifted back to surveillance testing. Now, public health laboratories are developing new surveillance systems, taking advantage of new equipment and staff, and improving programs based on lessons learned from the pandemic.
