ECHO-7 (trade name Rigvir) is a wild type member of the echovirus group of viruses.[1] It was formerly approved as a virotherapy medication by the State Agency of Medicines of the Republic of Latvia (2004–19).[2] In March 2019, the distribution in Latvia was stopped by the State Agency of Medicines, after laboratory tests found that the amount of ECHO-7 virus was in much smaller amounts than claimed.[3] On May 31, 2019, the State Agency of Medicines suspended the registration licence of ECHO-7.[4]
