A computer virus infected the networks and systems of three major hospitals including Barts, Royal London Hospital in Whitechapel and The London Chest Hospital in Bethnal Green Monday. The virus that infected the networks was the Mytob bug.
The virus is a type of backdoor that could have allowed hackers in the patient database of the three hospitals. The infection caused hospital personnel to use much slower manual data entry methods.
Attempts to fix the networks had failed. Officials say the three hospitals were open to walk-in patients only during the infection and that while treatment of patients wasn't affected new critically ill patients were diverted to other hospitals so slower manual systems wouldn’t affect their treatment.
