ECHO-7

ECHO-7 (trade name Rigvir) is a wild type member of the echovirus group of viruses. It was formerly approved as a virotherapy medication by the State Agency of Medicines of the Republic of Latvia (2004–19). 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. On May 31, 2019, the State Agency of Medicines suspended the registration licence of ECHO-7.
