Background Info
There are 35 diseases currently classified as 'Notifiable'. When a general practitioner or other doctor in attendance suspects that a patient is suffering from a Notifiable Disease, he or she is legally required to inform the Director of Public Health. The prime purpose of the Notifications system is to detect possible outbreaks, to initiate contact tracing eg tuberculosis and meningococcal disease, and to trigger investigation eg food poisoning rapidly. Accuracy of diagnosis is secondary and clinical suspicion of a notifiable infection is all that is required. If a diagnosis later proves incorrect, the notification can be amended. It also enables legal measures to be taken when necessary to control infection, for example, the exclusion from work of a foodhandler suffering from salmonella infection.
