Have to assume that's due in no small part to B.1.

Seven in 10 patients hospitalised with Covid-19 have still not fully recovered after five months, and they appear to cluster into four distinct categories based on their symptoms, research suggests.

The study, one of the world’s largest into long Covid in hospital patients, includes a group with persistent brain fog, which bears little relation to the severity of their other symptoms.

More than 300,000 Britons are estimated to have received hospital care for Covid-19 during the pandemic, and the UK-wide Phosp-Covid study has been following the health of 1,077 of those discharged between March and November 2020 – ranging from intensive care patients to some who only visited hospital for a few hours.

Five months later, the patients had nine persistent symptoms on average, with one in five meeting the threshold for a new disability. Among those who had previously been employed, 18% had been unable to work since developing Covid-19.
