There were more than 8,400 deaths linked to coronavirus in the third week of January - the second highest weekly number recorded during the pandemic, according to the Office for National Statistics (ONS).
It shows that a total of 117,378 deaths had occurred in the United Kingdom by January 22, where coronavirus was mentioned on the death certificate.
Deaths from COVID-19 in the Czech Republic reached 16,683 as of Tuesday, doubling since the end of November.
The ONS also estimated that one in nine people in private households in Wales is likely to have tested positive for Covid-19 antibodies by mid-January, up from one in 14 in December.
Last November, an Alcohol Change survey had showed nearly one in three drinkers had been drinking at increasing or high risk levels over the previous six months, with anxiety or stress cited as the main reason.
The ONS found substantial variation in the proportion of people estimated to have tested positive for Covid-19 antibodies across the regions of England.
In Wales, the total number of registered deaths in the week up to 22 January was 265 higher than the five-year average, although total deaths in Wales decreased by 93 from the previous week.
New cases, hospitalisations and deaths have been showing signs of declining in recent days, but at a far slower pace than during the first lockdown during spring past year.
This is the highest number of deaths to occur in a four-week period since April 10 to May 7 2020.
At the time, Wales had already been under a "level 4" lockdown, with schools conducting online learning rather than face-to-face teaching.
