In Israel, Prime Minister Benjamin Netanyahu said late Sunday that his country was largely unaffected by the ransomware attack after it began preparing for such events several years ago through its new National Cyberdefence Authority.
Dr Andrew Cowie, GP at Hawkhill Medical Centre and a member of the NHS Tayside Board, said all the information stored by the practice on Friday had been lost, but staff were still prepared to see patients who had an appointment.
At Broomfield Hospital, part of Mid Essex Hospital Services NHS Trust (Midlands & East), trauma patients are being diverted to Southend University Hospital.
But a spokesperson said these were not linked to the malware attack.
The NHS has warned the appointments at hospitals and GP may be slower than normal while the disruption caused by the ransomware attack subsides.
The statement said: "All outpatient clinics at York Hospital, Malton Hospital, Bridlington Hospital are going ahead".
Former National Intelligence Chief: U.S. Government "Under Assault" by Trump
So my statement was premised on, first, the context of our intelligence community assessment ... "I did not have any evidence". President Donald Trump fired FBI Director James Comey on Tuesday because Comey was a "showboat", according to the president.
It said: 'There were no infected computers in North East GP practices and the priority through this global malware incident was to protect the NHS computer network, clinical systems and patient data - and this was done very successfully. "Patients should continue to attend and contact their GP Practice in the usual way".
Cyber security experts say the brunt of the attacks were felt in Russian, including the country's largest mobile phone company.
Services are returning to normal, but some places are still having problems.
They should immediately update their Windows operating system and back up their data.
An insider at the Royal Lancaster Infirmary has said doctors and nurses were 'back to the 1980s using paper ' after a massive cyberattack affecting the NHS across the UK.

Comey also says it made him feel "mildly nauseous" to think his actions in October might have influenced the election outcome. He says he wants to determine whether the president attempted to influence or impede the FBI's investigation into Flynn.
"As a result of the swift action taken on Friday and over the weekend, the impact the attack had on local systems has been minimal and today all GP practices across Castle Point, Rochford and Southend are operational with only a few minor issues reported from some practices.
It was clear warnings were given to hospital trusts but this is not something that focused on attacking the NHS here in the United Kingdom".
It said in a statement: "NHS Digital issued a targeted update on a secure portal accessible to NHS staff on April 25, and then via a bulletin to more than 10,000 security and IT professionals on April 27 to alert them to this specific issue. This guidance was also reissued on Friday following the emergence of this issue".
Other Windows systems had also been affected and just 4.7% of NHS systems were still running XP, he said.
He said it was "too early to say" what the overall cost of the attack to public coffers would be. Britain's national health care system is still feeling the effects as gaining access to patient records is still a problem.
There is no evidence that patient data has been compromised in the hack which affected around 1% of computers in the NHS in Scotland, the Scottish Government said.
