Virtual 3-day congress

Due to the unpredictability of the COVID-19 pandemic and with your safety and health in mind, the IASSIDD Programme committee has decided to move to a fully Virtual IASSIDD Congress in July 2021.

You will be able to attend the IASSIDD congress 2021 in the comfort of your home or office: the congress will be online.

This means IASSIDD 2021 gives the international and local participant the opportunity to take part online. Engagement, interaction and networking with other delegates and speakers remain possible for all participants. 

Please note that, whilst it is now planned to host the IASSIDD 2021 congress as a virtual congress, we will continue to monitor the situation in the lead up to the event with the health and wellbeing of our delegates remaining our top priority.
