A disease outbreak is the occurrence of cases of disease in excess of what
would normally be expected in a defined community, geographical area or season.
an Outbreak is a term used in epidemiology to describe an occurrence of disease
greater than would otherwise be expected at a particular time and place. if we
are designing a data element, then we should use the term suspected disease or
outbreak.

Dear Knut and all,
Very interesting discussion. I would like to share my thought also on how
Sahana DMS included this. We had the concept of 'situation awareness' -which I
think is a well agreed term in surveillance. When counts reach a certain level,
it becomes an outbreak.
So, I think we may not need to introduce the data element 'outbreak', but a
means to define a threshold to any data element or indicator once aggregated
(eg. low hemoglobin in age group 1-14 years).
In creating each data element or indicator in DHIS2, we can flag it whether its
under surveillance. Also, another feature could be for the facility to set
thresholds to data elements or indicators marked for surveillance. Then it can
trigger notifications apart from mapping the cases on the map. Map legend would
be able to provide additional visual clues whether the condition is under
surveillance or reached the threshold (outbreak).
'Revers' of this process we used for inventory management. User can define
re-order levels and Sahana does the estimations and sends alerts.
Roshan
