Here is an opportunity to participate in a long-term research study about COVID-19 infection and return to diving. The study is being entirely sponsored by DAN.
DAN aims to collect information from up to 1,000 adult divers with confirmed or suspected COVID-19 infection, document recovery time and severity of the acute phase of their infection, and document diving practices and medical issues/health problems possibly encountered while diving after recovery from the disease.
The initial survey will take 15-20 minutes to complete. You will be contacted periodically by DAN over the next 5 years to follow- up on your diving career and possible medical issues.
You qualify for this study, if have/had a confirmed or suspected COVID-19 infection. If you decide to participate, you will receive a series of up to nine online surveys over the course of the next 5 years at various times with regards to dates, symptoms, and practices during your infection, recovery, and return to diving.
