NHS cyber attack update
12 May 2017, 6:54 p.m.
Great Ormond Street Hospital’s IT systems have not been affected by the virus that has hit some NHS services. There has been no impact on the treatment and care of patients.
We have, however, taken the precaution of isolating our computer systems and have closed down all external email services.
If you need to contact the Hospital urgently over the weekend, please call the main switchboard on: +44 (0)20 7405 9200.
