Virus replication produces a large mutational landscape that permits virus to rapidly adapt to changing environments. Emerging viruses pose a major threat to both human and veterinary health. This workshop will explore virus evolution and its consequences in transmission, immune evasion, and antiviral resistance. The 2020 ISEMPH Pre-Meeting Workshop has a separate registration fee ($150) from the ISEMPH Annual Meeting. You can register for both the ISEMPH Annual Meeting and Pre-Meeting Workshop using the ISEMPH Registration Portal. This registration site is for individuals who wish to only attend the ISEMPH Pre-Meeting Workshop on July 15, 2020. Cancellations for the pre-meeting workshop are accepted until June 30, 2020 (minus approximately 3% banking fees). No cancellations will be accepted after June 30, 2020.
