Urgent operations including surgery for cancer patients are being delayed by an outbreak of flu at a hospital. Addenbrooke’s Hospital in Cambridge said flu affecting dozens of patients has led to the closure of seven wards. The outbreak has also hit public areas and people are urged to stay away. Routine operations are being delayed and care services are being affected by the outbreak, medical director Dr Jag Ahluwalia said. He said: “The hospital is full and we’re struggling to cope. Some patients have had to be diverted to other hospitals. “We have high numbers of people with flu across the hospital. “For coughs, colds and flu-like illnesses, people are better off at home, resting and drinking plenty of fluids. “We need people to stay away from the hospital and ask themselves – do you need to be here?” Influenza is a virus so cannot be treated with antibiotics and in most cases it will run its course, the hospital said.
