A cyber attack that crashed a key cancer service at Waikato DHB, means up to 70 patients a day could be sent to Auckland for treatment, Stuff reports. The attack hit five hospitals and could cancel 350 treatments. Waikato DHB boss Kevin Snee noted that radiation therapy relies heavily on targeted and complex treatments driven by computer software. An Auckland DHB spokeswoman said the hospital is liaising with Waikato DHB regarding the possible transfer of a relatively small number of patients.
