Two samples tested positive for the UK strain of Covid-19 from Darjeeling and Kalimpong, said health department sources. Experts said that treatment of those infected by the Delta variant was the same but contamination rate was higher.
It has been declared as a Variant of Concern (VOC) by the World Health Organisation.
