Visitors are urged to avoid the Mary Coram aged care unit at Goulburn Valley Health due to a gastro outbreak. ‘‘We would like family and visitors to avoid the ward unless absolutely necessary,’’ a hospital spokeswoman said. ‘‘If they want to visit they are asked to call the hospital beforehand to see whether they can come in, to help avoid the spread of gastro.’’ It is believed the outbreak started yesterday. ‘‘We apologise for any inconvenience that this may cause,’’ the spokeswoman said.
