COVID-19, which means Coronavirus disease 2019, is a virus that can affect people of all ages in many ways. SARS-CoV-2 coronavirus that causes COVID-19 is challenging because it can have short- and long-term effects on multiple organ systems throughout the body, including the lungs (which appears to be its main target), kidneys, heart, and brain. NINDS is investing in research that will study the neurological complications of COVID-19.
