Dear colleagues and friends I am proud to invite you to the 5th international and 7th national congress of wound and tissue repair. In the interest of the health, safety and well-being of all registered attendees, our patients and families, as well as the general public, my colleages in the scientific and executive comittees have decided to organize 5th international and 7th national congress of wound and tissue repair as virtual congress for December 2-4, 2020. This decision has been taken due to the COVID-19 pandemic and in full support of public authorities in Islamic Republic of Iran and the World in their effort to slow the spread of the disease. It is hoped that, with the participation of scientists and clinicians, due to ideas sharing, new insights into wound management during COVID-19 pandemic will be achieved. Best wishes for good health to you, your families and your community.
