In June–November 2020, SARS-CoV-2-infected mink were detected in 290 of 1,147 Danish mink farms. In North Denmark Region, 30% (324/1,092) of people found connected to mink farms tested SARS-CoV-2-PCR-positive and approximately 27% (95% confidence interval (CI): 25–30) of SARS-CoV-2-strains from humans in the community were mink-associated. Measures proved insufficient to mitigate spread. On 4 November, the government ordered culling of all Danish mink. Farmed mink constitute a potential virus reservoir challenging pandemic control.

Tobacco smoking was found to be associated with an increased risk of dental caries. However, the overall poor quality of studies produced no validation for such an association. Further, more extensive research on this topic and prospective studies are needed.

The Cariogram risk profile showed strong correlations to the caries experience of Sardinian schoolchildren and that efforts to reduce caries risk are necessary.
