A total of 39,870 people who had close contact with Covid-19 patients or arrived from pandemic-hit areas are being quarantined nationwide.
As many as 2,549 patients have been given the all-clear, and the death toll remains at 35.
Among the patients under treatment, 19 have tested negative for the coronavirus once, 19 twice and 34 thrice.
After locally-infected cases were detected in late April, localities around the country are tightening epidemic prevention measures.
The Health Ministry urges all people to strictly follow the 5K motto: Khau trang (wearing facemask) – Khu khuan (disinfecting) – Khoang cach (keeping distance) – Khong tap trung (no gathering) – Khai bao y te (making health declaration), so as to contain the pandemic.
