More than 8,000 computer viruses have infected NHS computers over the last year, causing problems with patient records and appointments, according to official hospital documents.

The viruses caused appointments to be rescheduled without any prior notice given to patients, the loss of test results and NHS staff to be locked out of their computers for several days.

There is also the concern that personal information could have been at risk of theft, because the viruses that infected the computers are also used by hackers to steal personal information.
