The SARS-CoV-2 Omicron variant of concern (VOC) is rapidly replacing SARS-CoV-2 Delta in most European Union/European Economic Area (EU/EEA) countries, and is broadly following a west-to-east progression.
The risk to public health posed by the spread of the Omicron VOC in the context of ongoing Delta VOC transmission in the EU/EEA is assessed in this update.
The number of countries reporting SARS-CoV-2 Omicron variant of concern (VOC) cases continues to increase globally, with a total of 352 confirmed cases reported by 27 countries as of 16.00 on 1 December 2021, including 70 confirmed cases reported by 13 European Union and European Economic Area (EU/EEA) countries.
A SARS-CoV-2 variant belonging to Pango lineage B.1.1.529, with a high number of S-gene mutations compared to the original virus was detected at the beginning of November 2021. On 26 November 2021 the variant was designated a variant of concern (VOC) and assigned the label Omicron by the World Health Organization (WHO).
This Rapid Risk Assessment assesses the risk posed by the circulation of the Delta variant of SARS-CoV-2 between 1 December 2021 to 31 January 2022, based on modelling scenarios and projected levels of vaccination coverage.
Since January 2019, 121 cases of Salmonella enterica infections with six different serotypes linked to sesame-based products have been reported in five EU/EEA countries.
The risk assessed in this update is as follows: based on current levels of vaccination coverage and the dominance of the Delta variant in the EU/EEA, what risk does SARS-CoV-2 pose to the general population and the vulnerable population in the coming months?
Extreme rainfall on 14 and 15 July 2021 and subsequent flooding in Western Europe has taken a high number of human lives and caused substantial damage to community infrastructure and the environment. This rapid risk assessment focuses on the most common infectious diseases and health risks associated with flood-affected areas, taking into account evidence from previous similar events in Europe.
Coronavirus disease (COVID-19) outbreaks in long-term care facilities (LTCFs) in European Union and European Economic Area (EU/EEA) countries have caused significant morbidity and mortality since the beginning of the COVID-19 pandemic.
