Background: Two cases of deadly diphtheria detected in Lothian areapublished at 14:18 Greenwich Mean Time 12 November 2019
Two people are being treated in Scotland for the potentially deadly diphtheria infection.
NHS Lothian has confirmed the two cases are related and both patients are thought to be in hospital in Edinburgh.
The health board said those involved had recently returned from overseas.
Public health experts said the likelihood of any additional cases was very small, as most people were protected by immunisation given in childhood.
