The situation with visas to visit Senegal is fluid and the conference organiser is not able to offer definitive advice.
The following resources may be helpful:

All delegates should contact the Senegalese embassy or consulate in their own country. At a minimum, entrance into Senegal is likely to require a valid passport, proof of accommodation, proof of conference participation, and proof of a return air ticket.
If you need any administrative support from within Senegal, you can contact CTA Travel & Incentive, the destination management company appointed for AORTIC 2023. Please note that any service fee that they propose will be for your own account.
