outbreak history layer ongoing outbreaks

[n8layman]

How should we deal with ongoing outbreaks? For example, if the outbreak_start_date is before date but end_date is after date? The current approach is:

end_date = pmin(date, end_date, na.rm = T)

and then we filter such that,

 filter(date > end_date, years_since < max_years & years_since >= 0)

but date > end_date makes the pmin bit unnecessary. Are we also assuming that for an outbreak with a long interval all the cases happen on the end date? Or should we be splitting them up along the interval somehow?

Getting more fine-grained data for specific locations such as Tanzania may also be possible. @rostal mentioned that Harold may have more information. Mindy and I discussed that for now we don't need to spread the case data out over the interval and just to use the start and end dates.

Change recent outbreaks to 'spread risk' and old outbreaks to 'population level immunity'.
