Every month ECDC provides detailed epidemiological overview of the worldwide transmission of chikungunya in its weekly threat report (Communicable Diseases Threat Report).
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.
The mosquito species Aedes albopictus, a known vector of chikungunya and dengue viruses, is establishing itself further northwards and westwards in Europe, according to the latest data.
At the start of European Immunization Week, the ECDC report “Poliomyelitis situation update” reveals that between 2012 and 2021, approximately 2.4 million children in the EU/EEA may have not received three doses of polio-containing vaccines on time. Additionally, the newly published ECDC “Measles Annual Epidemiological Report 2022” highlights the risks when having pockets of an under-vaccinated population or groups not immunised at all.
Immediate health needs following earthquakes in Türkiye and Syria are mostly related to trauma and the disruption of healthcare, however, infectious disease threats may be concerning in the following two to four weeks.
Globally, as of 9 August, 19 cases of polio due to wild poliovirus type 1 (WPV1) and 223 cases due to circulating vaccine derived poliovirus (cVDPV) have been reported this year. In 2022, the cVDPV cases have been reported in 15 countries, with 93% of the cases attributed to cVDPV type 2 (cVDPV2).
According to the World Health Organization (WHO), one EU/EEA country (Romania) and two neighbouring countries (Bosnia and Herzegovina, and Ukraine) remain at high risk of a sustained polio outbreak partly due to insufficient vaccination coverage.
