A noticeable increase in signals of Covid transmission in the EU/EEA has been reported by the European Centre for Disease Prevention and Control (ECDC), deviating from previously very low levels.

 

Several factors have contributed to this increase, including large gatherings and increased travel. Additionally, there have been reports of waning levels of immunological protection against infection, although severe disease remains well protected against in the general population.

 

SARS-CoV-2 continues to acquire mutations that enable its circulation at unpredictable times throughout the year. Recent transmission increases have coincided with the emergence of Omicron sub-lineages, particularly the XBB.1.5-like variants.

 

As vaccination campaigns begin, countries should address factors that have previously hindered vaccine uptake. Effective communication campaigns involving healthcare professionals and the public are vital in emphasising the importance of Covid vaccination for high-risk groups.
