Although most people who have COVID-19 recover within a few weeks, some struggle with heart symptoms and problems such as brain fog, fatigue, headaches, dizziness, and difficulty breathing, even months after the initial infection goes away.

Doctors and scientists are working to understand these mysterious symptoms, sometimes called “long COVID”. Who has them? Why? How long do they usually last? To help answer these and other questions, NIH is funding research on the long-term effects of COVID-19, including long COVID and other conditions after COVID.
