The British government has said it is reducing the Covid-19 self-isolation period to seven days from 10 days for people in England who get a negative result on a lateral flow test two days in a row.

With the Omicron variant spreading rapidly in Britain and record levels of cases over the past week many industries are struggling with staff shortages, including hospitals who have warned of the risk of an impact on patient safety.

The UK Health Security Agency (UKHSA) said its analysis suggested a seven-day isolation period alongside two negative lateral flow test results had nearly the same protective effect as a 10-day isolation period without testing.

“We want to reduce the disruption from Covid-19 to people's everyday lives,” health secretary Sajid Javid said in a statement.
