South Korea confirmed two cases of the highly transmissible Delta plus COVID variant as the country battles its fourth wave.
“The first case (in South Korea) was identified in a man in his 40s who has no recent travel records,” said the Korea Disease Control and Prevention Agency (KDCA).
The KDCA said the second patient came from the US while there are no results from contract tracing yet.
Lee Sang-won, the head of the KDCA epidemiological investigations team said that both cases were breakthrough cases and that the patients had been fully vaccinated with AstraZeneca’s COVID-19 vaccine.
The Delta Plus variant is a sub-lineage of the Delta variant which has the spike protein mutation called K417N.
South Korea has so far confirmed 6,016 cases of four major COVID variants including 2,983 cases of Delta.
