NHS staff and terror attack victims and their families have been warned about the risks of using social media in new guidelines issued by NHS England.
The guide cautions that internet trolls may subject victims to «vile and upsetting abuse», as was seen after the Manchester and London terror attacks.
It also warns people to be wary of journalists seeking accounts of events.
The process of retelling a story can make people «relive the worst parts» of horrific events, it warns.
People may say more than they intend to when «vulnerable, upset or angry», it adds.
