The Delta strain, which was behind the deadly second wave in the country, of Covid still accounts for the maximum number of infection cases in Maharashtra, a senior official has said as per news agency ANI.

India has so far reported over 6,000 cases of highly infectious strain – Omicron, which was first detected in South Africa in November and started spreading in India from the first week of December. 

Till Friday night, Maharashtra has reported 1,605 Omicron cases, while its overall infection tally has jumped to 71,24,278. 

In his letter, Vyas said since November 1 last year, the samples of 4,265 Covid patients were sent for genome sequencing. The results of 4,201 cases have been issued, which indicate that Omicron variant was detected in 1,367 cases or in 32%, while the prevalence of Delta variant was found in the remaining 68% cases. 

It also said that of the 2,40,133 active cases in the state till Wednesday (January 12), 90% patients were in home isolation or in Covid Care Centres.
