Lisbon, May 18, 2020

Dear colleagues 

The ISA2020, which was due to run this week, has been postponed due to the COVID-19 (novel coronavirus) outbreak. 

The effort to slow the spread of COVID-19 has temporarily halted the scientific meetings as countries and states have banned gatherings of all sizes and organizations have put travel on hold. But as disruptive as these measures have been, resulting in countless conventions and meetings having to be cancelled, postponed or moved to online-only, standing committee have decided to hold our event and move it to a later date when the public-health crisis (hopefully) eases. 
The decision to postpone the conference has been taken to minimize costs and risks for all involved, in the wake of decision by the World Health Organization to declare COVID-19 a global pandemic, as well as, our country government rules.  

The planning of the conference was well underway, with more than 543 registered participants and 72 confirmed oral communications and 490 poster communications scheduled to take place over the course of five days.  
The ISA2020 conference scheduled to be held in Lisbon on May 18-22 was set to be one of the biggest events of ISA. Everyone involved - the Lisbon local organizing committee and ISA’s Standing Committee, have worked tirelessly to ensure that ISA2020 would be a truly outstanding symposium. It was particularly important for the local organizing committee that the event was to be held in Lisbon, Portugal, for the first time of ISA events.  
In addition to all the work of the organizers, planners and designers, there was also the work of all the participants: the panel organizers, the paper contributors, the convenors, and special events organizers. It has been an enormous undertaking. Yet as the tragedy of the Covid-19 emergency unfolded, the likelihood of being able to hold this conference as planned became smaller with every passing day. 

As a result, the Conference was postponed to Spring 2021 and we are now pleased to announce the new dates as 10 to 14 May 2021 in Lisbon Portugal!

We sincerely apologize for any inconvenience this will cause for you. We trust that you understand that we made this decision in the best interests of all of you. We wish to assure you that your agreements, registration and participation are unchanged and valid for the new dates. We look very much forward to welcoming you at ISA 2020 in May 2021. 
The conference organizers invite all participants to continue their engagement with this event and will work towards ensuring the programme with an even greater level of participation in May 2021.  
All abstracts previously submitted will continue to be valid for the symposium, unless participants wish to make any changes. New submissions will be possible and will be considered according to the slots available. The registrations and payments already made will be maintained.  
By the end of this year a new date for early registration will be announced. 
Looking forward to welcoming you all in good health in Lisbon May 2021 for ISA2020
