The death rate in England and Wales is around a third higher than normal for this time of year, official figures show.

Some 28,800 deaths were registered in the fortnight ending January 23, according to the Office for National Statistics (ONS).

This is 32% higher than the average for that period over the previous five years (21,859).

The ONS suggested that the flu virus and the cold snap could be to blame for the increased death rate.

The latest analysis by Public Health England (PHE) found that deaths among people aged over 65 have been higher than expected for six weeks, even taking the time of year into account.

Dr Richard Pebody, head of seasonal flu surveillance at PHE, said: "In recent weeks we have seen evidence of significant excess mortality, particularly in the elderly, with more deaths than expected at this time of the year.

"Two important causes of excess deaths during the winter are influenza and cold snaps, although estimating exactly how much can be attributed to each takes more time.

"The main type of flu that has been circulating this winter so far is well recognised to particularly impact groups such as the elderly and those with underlying chronic health problems, resulting in increases in hospitalisations and deaths. That is why we recommend these groups receive flu vaccine each year ideally before the flu season starts.

"Throughout the winter season PHE also encourages the early prescribing of antivirals for the treatment of flu and prophylaxis of vulnerable populations to reduce their risk of serious illness. We also offer advice throughout winter to health professionals and the public about staying safe and healthy in cold weather - which includes looking out for older people who may be more at risk from the effects of very cold weather."
