No new coronavirus cases were reported over the past 24 hours, but people should remain cautious because there were still infected people undetected in the community, the government said on Friday.
Taweesilp Visanuyothin, of the Centre for Covid-19 Situation Administration, said that in the period May 8 to 21, 45 people tested positive for the disease. Twenty of them were infected in other countries and were quarantined on return to Thailand.
The 25 local infections consisted of 11 people who were in close contact with previously confirmed cases, six found by preemptive testing in communities, five who visited crowded places, and three people in at-risk professions.
"The 25 people had been around in everyday life and this proves that infected people are still out there. So, people cannot be reckless," Dr Taweesilp said.
Of the 3,037 local Covid-19 cases, 2,910 had recovered and 71 patients remained at hospitals. The death toll remained at 56.
