Every month ECDC provides detailed epidemiological overview of the worldwide transmission of chikungunya in its weekly threat report (Communicable Diseases Threat Report).
ECDC regularly assesses new evidence on variants detected through epidemic intelligence, rules-based genomic variant screening or other scientific sources.
European Immunization Week (EIW) is marked across Europe every year in the final week of April. It aims to raise awareness of the importance of immunisation for the general health and well-being of the European and wider population.
In connection with the European Immunization Week, ECDC releases data indicating an increase in cases of vaccine-preventable diseases such as measles and pertussis, after decreased levels during the COVID-19 pandemic.
