Underlying Health Conditions, Turner Syndrome, and the COVID-19 Virus
Are people with Turner syndrome (TS) at a higher risk of contracting the COVID-19 virus? This is a question we're receiving from many members of our community. We're providing this information to help people with TS determine if they have an underlying TS-related health condition that makes them more vulnerable to serious complications of COVID-19.
