Canterbury DHB makes changes to visiting as cases of respiratory illness rise in community Following an increase in viral respiratory illness being seen in the community, Canterbury DHB has made changes to visiting for Christchurch and Burwood Hospitals today – effective immediately. Canterbury DHB Chief Medical Officer Dr Helen Skinner says there is currently increased demand for the DHB’s hospital-based services due to a rise in patients presenting with respiratory illness and we need to do whatever we can to prevent the spread of illness in our facilities. “For that reason, we are requesting that people only visit Christchurch and Burwood Hospitals for essential purposes only and stay home if they are unwell.
