Epsilon variant, also known as CAL.20C and referring to two PANGO lineages B.1.427 and B.1.429, is one of the variants of SARS-CoV-2, the virus that causes COVID-19. It was first detected in California , USA in July 2020.
[1] On March 12, 2021, Japan detected the variant on a traveler from the Philippines. [2] On March 13, 2021, the Department of Health confirmed the mutations constituted a new variant, which was designated as lineage P.3.
