Although COVID-19 in major of the area are under control due to the great efforts of all people, especially health care workers, we are still facing the challenges across the world. The Organizing Committee of ASSM 2021 recognizes and respects the uncertainty that currently exists regarding the prospect of international travel and large-scale gatherings. This has been a difficult and unprecedented decision for a difficult and unprecedented moment. However, the health, comfort and safety of all of our attendees are paramount. Postponing the ASSM 2021 Congress will allow us to regroup and deliver the safe environment and a top-notch event our delegates deserve. The rescheduled ASSM 2021 will be considered to provide an online, virtual event as well as a live, in-person meeting due to health and safety concerns, which will be more accessible than ever before.

The registration and paper submission accesses are now still open, you are welcomed to join us to present a premier sleep event.

The ASSM is thankful for your patience, your loyal and enduring supports. We are grateful for you, and we remain committed to delivering a sleep event that exceeds your expectations.

We look forward to meeting you in Beijing, China in 2021.
