The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has ripped through the world, causing millions of new acute infections. Many of these develop coronavirus disease 2019 (COVID-19), and some are left with post-acute sequelae.
This is sometimes called long covid. A new study from Germany presents data on long covid in adults and children, which is becoming a major issue in public health planning.
