She said the contacts of the seven Delta cases will be traced, and it will be checked if the patients had travelled abroad.

Given that the Delta variant is much more transmissible, many more cases are expected within a couple of week, Hristova said.

She added that the vaccines used in Bulgaria are effective against the Beta and Delta variants, and warned about a new spike in infections in the summer.
