London (CNN) The true death toll from coronavirus in England and Wales up to April 10 was about 41% higher than the UK government's daily update, according to data released by the country's Office of National Statistics (ONS).

The daily updates on the government's website only include deaths in hospitals -- not other locations, including hospices, care homes and private residences. They also don't account for the lag in reporting some deaths.

The weekly data released by the ONS records deaths where coronavirus is mentioned on the death certificate -- even if only suspected. The latest ONS data for deaths up to April 10 (but recorded by April 18) is 13,121
