The genome sequencing of samples of two Covid-19 patients who have since recovered has revealed that they were infected with the Delta variant of the virus, a senior official from Indore in Madhya Pradesh said on Friday.

The samples were sent in July and a report from the Delhi-based National Centre for Disease Control (NCDC) had arrived now, said Dr Amit Malakar, nodal officer for prevention of Covid-19 here, adding that both had recovered since.
