The National Institute of Public Health in Norway (FHI) released their Annual Report of Outbreaks of Infectious Diseases in Norway in 2020 today which states that in 2020, 561 outbreaks (that were detected) were reported with a total of 7,430 reported cases of the disease last year.
This corresponds to a large increase in the number of announced outbreaks compared with 2019 (223 outbreaks).
However, the increase is due to reports of outbreaks of SARS-CoV-2 (453 of a total of 561 reported outbreaks). This means that the number of alerts about outbreaks for other agents was halved in 2020.
Alerts about outbreaks of SARS-CoV-2 dominated among alerts from health institutions (141 outbreaks) followed by norovirus (43 outbreaks). For health institutions, there were far fewer warnings of outbreaks of norovirus in 2020 compared with the two previous years (43 against 82 and 98 in 2018 and 2019, respectively). The number of notified foodborne outbreaks was halved in 2020 (23 outbreaks) compared with 2019 (46 outbreaks).
Of all reported outbreaks, 40% (222 outbreaks) were reported by health institutions, while for only 4% of the notifications in 2020 (23 outbreaks) there was a suspicion of infection from food. The remaining 56% (316 outbreaks) were warnings of other outbreaks, the majority of which were warnings of outbreaks of SARS-CoV-2 (312 of 316 outbreaks). The number of patients registered in each outbreak varied from 2 to 203 people (median 8 people).
