India, Sept. 24 -- The Institute of Genomics and Integrative Biology (IGIB) in Delhi has been working with four states to set up "megalabs" that can sequence up to 3,000 viral genomes of the Sars-CoV-2 that causes the coronavirus disease (Covid-19). The states, which are expected to make separate announcements to the effect, weren't named.

Not only will genome sequencing be more accurate than the reverse transcriptase-polymerase chain reaction (RT-PCR) test at detecting infection in clinical samples, but the data will also be used for routine surveillance of the virus and where it originates to help the government in devising more effective strategies to control its spread. RT-PCR is now considered the gold standard for diagnosis of the ...
