Weekly number of reported campylobacteriosis cases in Germany, 2002-2011, together with the corresponding absolute humidity (in g/m^3) that week. The absolute humidity was computed according to the procedure by Dengler (1997) using the means of representative weather station data from the German Climate service.
data.frame containing the following columns
Date instance containing the Monday of the
Number of reported cases that week.
Boolean indicating whether there is external knowledge about an outbreak that week
Mean absolute humidity (in g/m^3) of that week as measured by a single representative weather station.

Boolean indicating whether the reporting week corresponds to the first two weeks of the year (TRUE) or not (FALSE). Note: The first week of a year is here defined as the first reporting week, which has its corresponding Monday within new year.
Boolean indicating whether the reporting week
corresponds to the last two weeks of the year (TRUE) or not
(FALSE). Note: This are the first two weeks before the
Boolean indicating whether the reporting week corresponds to the W21-W30 period of increased gastroenteritis awareness during the O104:H4 STEC outbreak.
The data on campylobacteriosis cases have been queried from the Survstat@RKI database of the German Robert Koch Institute (https://survstat.rki.de/).
Data for the computation of absolute humidity were obtained from the German Climate Service (Deutscher Wetterdienst), Climate data of Germany, available at https://www.dwd.de.
