The UK has recorded its highest daily coronavirus cases since late February, suggesting the Delta variant is spreading widely across the country.

Government figures Wednesday showed that the UK recorded 7,540 new infections, the biggest daily increase since Feb. 26. Cases have been rising over the past few weeks as a result of the Delta variant first identified in India.

The concern is the increase will pressure the health system once again.

Another 123 people entered the hospital with symptoms related to coronavirus, taking the total to 1,024. The number of people dying after testing positive for COVID-19 rose by six to 127,860 confirmed deaths.

Health experts hope the rapid rollout of vaccines will break the link between new cases and deaths. So far, a large proportion of the people infected are within the less vulnerable younger age groups, many of whom have yet to receive a first dose.
