Less than half per cent (0.5%) of the 345 international arrivals tested at Delhi Airport till Sunday evening tested positive for Covid. The low percentage of positive cases so far has brought relief to authorities here, as IGIA had seen a peak of 5-6% last summer at the height of Delta wave, say officials of Genestrings Diagnostic Centre’s lab which has been conducting tests at Delhi Airport during the pandemic. Everyone is keeping their fingers firmly crossed.
