UPDATE: @BorisJohnson is *receiving oxygen* in hospital, as he was "more seriously ill than either he or his officials were prepared to admit." Boris reportedly "was being seen by doctors who were concerned about his breathing."

Boris Johnson's condition is serious. Patients with severe #COVID19 illness often are hospitalized in the 2nd week of illness (Boris tested positive 11 days ago). The next few days will be crucial to see whether makes a turn for the better or worse.https://t.co/io9JfgdMFk
