There were 29 more Covid-19 fatalities and 3,370 new cases registered during the previous 24 hours, the Public Health Ministry said on Wednesday morning.
On Tuesday, 4,557 Covid-19 patients left hospitals after recovering from the coronavirus.
Since the pandemic started early last year, there have been 2,178,276 Covid-19 cases, with 2,110,701 complete recoveries so far.
The vast majority of the Covid cases and deaths have occurred since April 1, around when the third wave of Covid-19 began.
The death toll stood at 21,260 since the beginning of the pandemic.
Sumanee Wacharasin of the Department of Disease Control said the 29 latest fatalities were aged 23 to 93 years and included one foreigner, a Myanmar national. Twenty-one of them were not vaccinated.
The fatalities included a pregnant woman, 43, in Chon Buri, who had diabetes and was not vaccinated.
Bangkok logged three new deaths.
The 3,370 new cases included 3,239 local infections and 20 imported cases.
Bangkok had 583 new cases, followed by 172 in Chon Buri, 150 in Nakhon Si Thammarat, 140 in Samut Prakan, 135 in Songkhla, 117 in Pattani, 97 in Surat Thani, 89 in Chiang Mai, 76 in Prachin Buri and 71 in Trang.
“Clusters of new infections may grow during long holidays at markets and eateries, especially at grilled pork places where customers share pans and stay a long time,” Dr Sumanee said.
Dr Sumanee said Omicron infections had been confirmed in 70 countries and were spreading fast in the United Kingdom, Denmark and Norway. China confirmed its first Omicron case in an arrival, she said.
The government confirmed eight Omicron cases with others suspected.
