Antibody Response Affects COVID-19 Outcomes in Kids and Adults

Doctors can’t reliably predict whether an adult newly diagnosed with COVID-19 will recover quickly or battle life-threatening complications. The same is true for children. Fortunately, the vast majority of kids with COVID-19 don’t get sick or show only mild flu-like symptoms. But a small percentage develop a delayed but extremely troubling syndrome called multisystem inflammatory syndrome in children (MIS-C). This can cause severe inflammation of the heart, lungs, kidneys, brain, and other parts of the body, coming on weeks after recovering from COVID-19. Thankfully, most kids respond to treatment and make rapid recoveries.
