The government recorded 1,630 new coronavirus cases on Monday, and 22 deaths.

The infection figure was sharply lower than Sunday's tally of 2,101, taking the total since the beginning of the pandemic to 85,005.

The death toll passed 400, however, rising by 22 to 421.

The Centre for Covid-19 Situation Administration (CCSA) said on Monday the fatalities were 13 victims in Bangkok, two in Chiang Mai and one each in Chachoengsao, Khon Kaen, Maha Sarakham, Pathum Thani, Rayong, Samut Prakan and Suphan Buri.

Two died the same day they received their test  results, while seven others passed away within a week of their diagnoses.

The number of new cases in Bangkok dropped by almost by half from the 980 recorded on Sunday to 565 on Monday, but the capital still logged more cases than any other province. Nonthaburi came second with 158 cases, followed by Samut Prakan (116) and Samut Sakhon (85).

Clusters under surveillance in Bangkok were Soi Phetchaburi 5 and 6 in Ratchathewi district and an office building in Yannawa district.

There were also eight imported cases.
