The development comes in the wake of the Union Health Minister Mansukh Mandaviya reviewing the situation and asking people to follow Covid-appropriate behaviour, including wearing masks in crowded places, and getting vaccinated. "Considering the importance of monitoring the trends of existing variants, it is essential to gear up the whole genome sequencing of all positive case samples through Genome Sequencing Labs. This will enable timely detection of newer variants, if any and will facilitate undertaking of requisite public health measures for the same," Additional Chief Secretary, Health, Arun Kumar Singh told PTI.
