Health NZ steps up precautations after two superbug outbreaks

Health New Zealand has stepped up precautions after two confirmed separate outbreaks of antibiotic-resistant super bugs at Christchurch Hospital. It says there are fewer than 10 patients with the infection known as VRE but many are asymptomatic carriers. The bacteria is difficult to treat due to its resistance and in some case can be potentially life threatening. Associate Professor Mark Thomas, an infectious diseases researcher at the University of Auckland, spoke to Lisa Owen.
