This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 17-23 December 2023 and includes updates on cholera, SARS-CoV-2 variant classification, avian influenza in fur farms, hepatitis A, pertussis, a cluster of extensively drug-resistant Shigella Sonnei among men who have sex with men, and an overview of respiratory virus epidemiology in the EU/EE.
This document is an update of the joint guidance that was published in 2011 by the European Centre for Disease Prevention and Control (ECDC) and the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA).
Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis C. Case-based surveillance has limitations as most diagnosed cases are chronic in nature and detection of cases depends largely on testing practices. Prevalence data can therefore contribute towards a fuller understanding of the epidemiology of hepatitis C.
Since April 2023, over 300 shigellosis cases, many with multidrug-resistant Shigella sonnei -infections, have been reported to the European Centre for Disease Prevention and Control (ECDC).
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 19-25 March 2023 and includes updates on Marburg virus disease, iatrogenic botulism, COVID-19, Influenza, Group A streptococcal infection, cholera, poliomyelitis, measles, and extensively drug-resistant Pseudomonas aeruginosa.
