Concerns after track and trace tells doctors to self isolate Dr Rob Galloway is pleading for those who need emergency treatment to come to A&E. Photo: BBC News THE Royal Sussex hospital is facing being left short-staffed because of double vaccinated doctors being told to self-isolate - despite testing negative. The shortage comes amid rising rates within Brighton and Hove, leading to many close contacts being "pinged" by the Track and Trace app. Those deemed "close contacts" of positive cases must self-isolate for ten days from that contact, regardless of negative test results. Rob Galloway, A&E consultant at the Royal Sussex, has called on Public Health England to explain the benefits of its Track and Trace system.
