This was also the first time in the UT that over 1,000 samples were tested within a span of 24 hours, the officials said.
"Finally, J&K breaks the 1,000-test barrier - 1,071 samples tested in the last 24 hours. But that also means more positives. So 40 new cases today," government spokesperson Rohit Kansal said.
All the fresh cases are from Kashmir, he said.
Of the total 494 cases, 437 are in the Valley and 57 in Jammu region, Kansal said, adding that 109 patients have recovered so far.
